CHEMICAL TESTING OF YOUR POOL

 Chemical tests and adjustments alone will not promote proper water chemistry. Rather, adequate circulation and filtration, as well as the pursuit of a routine maintenance schedule are also required. In order to perform routine maintenance, you have to become familiar with your maintenance equipment:


TESTING DEVICE

TELEPOLE

NETS

BRUSH

MANUAL VACUUM ASSEMBLY

AUTOMATIC VACUUM CLEANERS

DERLIN SPRING

CONNECTOR PIN

GARDEN HOSE OPERATED VACCUM

BACKWASH HOSE

AUTOMATIC WATER LEVELER 

TEST DEVICE:
 You must constantly test for chlorine (or its alternative), pH, and Alkalinity at the poolside. Approximately once per month, or if unusual pool readings occur, take a water sample to your local pool professionals and have them test every chemical reading on the computer. Test chlorine (or its alternative), as well as pH and Alkalinity, 2 - 3 times per week during normal weather conditions and under normal use. Test chlorine (or its alternative) daily during periods of scorching temperatures, unbearable humidity, and intense sunlight, as these are the times when bather load is at its highest. Test chlorine (or its alternative), as well as pH and Alkalinity, after heavy rainfall, before and after a pool party, and, of course, if water appears to be cloudy, murky, or beginning to form algae. The only way that you can accurately depict the condition of your water is by administering the actual tests. Either with test strips or test kits, the tests only take minutes to perform. Test strips and reagents (or tablets) for test kits are also inexpensive.
TELEPOLE:
  A long aluminum pole that can extend to various lengths in order to complete its intended maintenance procedure at any area and at any depth of the pool. The telepole attaches to your nets, brush, vacuum assembly, and other maintenance equipment in order to perform a maintenance task. The telepole also attaches to the "Shepherd's Crook," which is a life-hook (a life-saving device).
NETS:
There are two styles of standard pool nets: Deep Net and Skimmer Net.

  • The deep net, which is often called a leaf rake, has a wide opening and a deep net. This style of net is primarily used to reach leaves or other large debris that have settled to the pool floor. The deep net can also be used to skim leaves and debris off the surface of the water, but the skimmer net is best at performing this task.
  • The skimmer net, which has a shallow net, is primarily used to remove leaves, grass clippings, debris, or insects that float on the surface of the water.
BRUSH:
 Typically, a brush is 18" in length and has either nylon bristles or stainless steel bristles. The brush is used to brush away dirt and debris, as well as algae, from the pool walls and floor. There are also specialized brushes, such as an algae brush (only used to brush away algae) and a corner brush (to brush away dirt or debris, as well as algae, from the corners, where the walls meet the floor, and at the faceplates of the skimmers and return jets, where stubborn dirt, debris and algae is capable of escaping the standard 18" brush).
The nylon bristle brush can be used with any type of pool to brush away dirt, debris, or Green and Mustard Algae. The stainless steel bristle brush can only be used on a concrete, gunite, shotcrete, or fiberglass pool to remove stubborn Black Algae, stubborn dirt, any stains or scale. A stainless steel bristle brush can never be used with a vinyl-liner pool (it is too abrasive and may tear the liner).
MANUAL VACUUM ASSEMBLY:
  Consists of the vac head, the vacuum hose, the telepole, and perhaps a vacuum seal plate. There are two styles of vac heads: the brush-style vac head and the wheel-style vac head. A brush-style vac head is used for vinyl liner pools. A wheel-style vac head is used for concrete, gunite, shotcrete, and fiberglass pools. One end of the vacuum hose will connect to the vac head and the other end of the vacuum hose will connect to your skimmer. If so, a vacuum seal plate should be placed over the skimmer in order to trap optimal suction to complete the vacuum. Some pools have a designated vacuum line. If this is the case with your pool, connect the vacuum hose to this designated vacuum line instead of the skimmer. Use the telepole to maneuver the vacuum assembly across the pool floor and walls.
AUTOMATIC VACUUM CLEANERS:
 A vacuum cleaner that will vacuum your pool for you. Regardless of the brand and type of automatic vacuum cleaner, if you can afford one, buy one. They are a worthwhile investment. But, even if you own an automatic vacuum cleaner, you will still need to use your manual vacuum assembly in these situations:

  • The pool has just been opened (after previously being winterized). After opening, a large amount of dirt and debris is typically present on the walls and floor.
  • Any time that a large amount of dirt and debris are present on the walls or floor.
  • Algae is present.
DELRIN SPRING:
 The spring that allows certain maintenance equipment (like nets, the brush, and the vac head) to attach to the telepole. Delrin Springs will break. But, they are extremely inexpensive. Purchase a half dozen at a time, store them with the rest of your maintenance equipment, and replenish your stock when you are down to your last Delrin Spring.
CONNECTOR PIN: Some maintenance equipment use Connector Pins to attach to the telepole. Connector Pins will break or get lost. But, they are extremely inexpensive. Purchase a half dozen at a time, store them with the rest of your maintenance equipment, and replenish your stock when you are down to your last Connector Pin.
GARDEN HOSE OPERATED VACUUM:
 Some pools do not have suction lines in order to vacuum the pool with a manual vacuum assembly. In order to vacuum these pools, a garden hose operated vacuum is used. There are two types of vacuum units: the brush-style vacuum unit and the wheel-style vacuum unit. The brush-style vacuum unit is used for vinyl-liner pools. The wheel-style vacuum unit is used for concrete, gunite, shotcrete, and fiberglass pools. Your standard garden hose will attach to the vacuum unit. The running water from your garden hose will create suction, drawing the leaves, dirt, and other debris into the silt bag of the vacuum unit. Once full, empty the silt bag, reattach it to the vacuum unit, and start again until the silt bag is full.
Many pool owners with the capability to use a manual vacuum assembly will also have a hose operated vacuum unit in their possession. If there is an enormous amount of leaves and other large debris on the pool floor-to much to net out and such a large amount that would clog your vacuum hose-the hose operated vacuum unit works great. The only drawback is that the silt bag can only hold so many leaves and other debris until the unit must be taken out of the pool, emptied, reattached, and sent back into the pool.
BACKWASH HOSE:
 Some pools do not have a plumbed in waste-line. Either local code or restrictions in your area did not allow for the waste-line. If your pool does not have a waste-line, simply purchase backwash hose from your local pool professionals. Backwash hose will allow you to manually create a waste-line any time you need one.
AUTOMATIC WATER LEVELER:
 Not at all considered maintenance equipment, but it is a very valuable accessory for your pool. Due to evaporation and splash-out, you will lose water, which will have to be replaced. The Water Leveler will sit on your pool deck and hang over the pool. Your garden hose will thread into the hose adapter on the part of the Water Leveler that sits on your pool deck. A float is installed on the part of the Water Leveler that hangs over the wall and into the pool. You will have to adjust the float to turn "off" the Water Leveler when the fill water reaches the desired water level (half way up the skimmer). The float on the Water Leveler is very easy to adjust. This accessory is very worthwhile.

DUTIES AND WORK OF A LANDSCAPE ARCHITECT

Landscape architects create the landscape around us. They plan, design and manage open spaces including both natural and built environments.
They work to provide innovative and aesthetically pleasing environments for people to enjoy, whilst ensuring that changes to the natural environment are appropriate, sensitive and sustainable.
The work covers diverse projects - both urban and rural - that range from designing the layout of parks, gardens and housing estates to city-centre design, sporting sites and improving land affected by mining or motorway construction.
A landscape architect collaborates closely with landscape contractors, as well as other professionals, especially architects, town planners, environmentalists and people working in surveying and engineering functions.

Typical work activities

The role of a landscape architect commonly includes some or all of the following:
  • overseeing the design of a variety of projects, including urban regeneration schemes, pedestrian schemes, road or retail schemes, and maintaining the character of sites of natural beauty;
  • establishing general landscape requirements with clients;
  • conducting preliminary studies of the site (including contours, soil, ecology, buildings, roads);
  • assessing a site's potential to meet the client's specifications;
  • carrying out environmental impact assessments;
  • seeking and taking into account the views of local residents, potential users, and parties with a vested interest in the project;
  • accurately preparing and presenting detailed plans and working drawings, including applications, construction details and specifications for the project using computer-aided design (CAD) packages or similar design software;
  • presenting proposals to clients, dealing with enquiries and negotiating any amendments to the final design;
  • matching the client's wishes with your knowledge of what will work best;
  • contacting and coordinating manufacturers and suppliers;
  • putting work out to tender, selecting a contractor and manager (mainly for larger projects), and leading cross-functional teams;
  • making site visits;
  • ensuring deadlines are met;
  • liaising with other professionals on the project;
  • monitoring and checking work on-site (on large projects, landscape managers may do this type of supervisory work);
  • authorising payment once work has been satisfactorily completed;
  • attending public inquiries to give evidence if necessary;
  • generating new business opportunities.

THE REQUIREMENTS FOR KEEPING CICHLIDS

The Requirements for Keeping Cichlids

If you want to keep African Cichlids, have them spawn, and have them live a long life, exhibiting the optimum of their beautiful colouration and their most endearing traits, you must learn how to simulate the conditions of the African Rift Lakes.

THE WATER

All African Cichlids should be kept in water with a pH of 7.5-9.0, a water hardness from 10-20 dH, and a temperature between 25-28°C.
The actual ranges of theAfricanRiftLakesare:

Lake Tanganyika — 7.8-9.0
Lake Malawi —  7.4-8.4
Lake Victoria — 7.2-8.6 

Naturally, these values are always approximations, because ranges in nature often fluctuate and may thus be more or less, but the values stated above have been found to be best tolerated by Cichlids in aquaria.
The native waters of the African Cichlids is also very hard, containing many dissolved minerals and salts.
Since all African Cichlids appreciate this higher pH, these are one of the few fish species whose aquariums may be decorated (or supplemented)  with coral and shells, which normally push the pH of a freshwater aquarium above most fishes’ natural ranges. In some instances, it may, however, still be necessary to buffer water to reach these higher pH levels. There are many suitable commercial “Cichlid Buffers” on the market which can be used. Many of these manufacturers also offer “Cichlid Salts” and “Trace Elements”. We recommend using both the salts and trace elements, as fish which are kept in water containing them often exhibit superior coloration — simply because they are in water which more exactly recreates their natural conditions.

THE AQUARIUM

The next thing to consider is the aquarium itself. Because of their nature, Cichlids ideally should be housed in large tanks! How large? As large as you can possibly afford! When choosing the size and shape of a Cichlid aquarium, it is important to remember:  the larger the capacity and the more surface area (length x width), the greater becomes the selection  of Cichlids you could choose from. Larger tanks are also more easily stabilised and kept stable that smaller tanks. In addition, larger tanks provide more space for individual territories, which means fewer losses due to aggression. Tank width always takes precedence over depth, simply because a greater width allows for more — and strategically better placed — rock structures. 
The cichlid aquarium also needs to be over-filtered, not only because Cichlids are greedy feeders and heavy excreters, especially of urine, but also because, unlike the slow, but constant fresh food supply in nature, feeding in aquaria takes place in short bursts, creating conditions which require higher filtration. Take care to choose a filter that helps create flow, but NOT any heavy current in your tank. Aeration is equally important in a Cichlid aquarium, because Cichlids require well oxygenated water.

THE DECOR

As far as tank décor is concerned, a cichlid tank must have rock structures suited to the nature of the specific species kept. I cannot emphasise enough how important a properly structured habitat is to Cichlids. However large the tanks we choose may be, they remain minuscule in comparison to the natural habitat available to Cichlids in the wild! If you really stopped to let this point sink in, it must be obvious why most Cichlid keepers have such a struggle with in-tank aggression!
I was appalled, recently,  at the solution of a cichlid keeper who had no qualms about publishing his solution to aggression on a well-known Cichlid forum: Removing all structures in the tank that could encourage his Cichlids to claim territories! Perhaps even more appalling was the fact that not a single forum member criticised this solution! In catering to his own selfish needs, this Cichlid-keeper completely disregards the needs of the species he keeps. Yet there is no doubt in my mind that this person is in fact the origin of the aggression in his tank.  
The very nature of Cichlids is to be aggressive about territory,  food and  mates. It is an evolutionary trait without which they could not survive in the wild! When we house Cichlids in aquaria, we also have to accommodate their nature. The truth is that there is a remedy to in-tank aggression, and a very natural remedy at that!
Studies have found that the influence of habitat type is one of the greatest aggression triggers for Cichlid males –  and irrespective of the species, that aggression is directed equally at con- and heterospecifics. In fact, these recent findings tell us that habitat complexity plays a much larger role in shaping aggressive behaviour than most other suggested factors, such as competition for food resources, or even spawning and breeding.
The primary requirement for relative peace in a Cichlid tank is sufficient rock-work, arranged aesthetically for your own sake, but strategically for the fish’s sake, to provide as many as possible niches, caves, hides and retreats — the ideal being at least one suitable retreat per fish, but preferably more. If the rock-work is well-placed and also arranged in layout patterns that further help delineate a range of separate territories, as well as opportunities for making, or claiming territories, habitat induced aggression should soon be adequately dealt with.
Most Cichlid tanks are not aquascaped to the optimum. The rock-work often reaches no higher than halfway up towards the water surface, wasting the entire upper half of the tank space that could be used to create caves and niches that help alleviate territorial disputes. 
At this point I would also like to bring to your attention just how crucial habitat is to breeding your Cichlids.
Many aquarists fail to breed Cichlids successfully, despite setting up dedicated breeding tanks, selecting pairs carefully and keeping water conditions correct and stable, despite water changes and a special feeding regimen. Yet, just as many aquarists do almost none of the above and have no problems breeding their cichlids at all. They simply keep their Cichlids in their normal display tanks, make sure the water conditions are perfect and then let nature take it course. And strangely,  these latter aquarists  sometimes have to try to devise ways with which to stop their Cichlids breeding so much!
So, what is the difference between these two groups?
There is indeed a secret. It is so simple, I am sure it will almost floor you, but if you think it through, it does make complete sense. The answer, in short, is this: Habitat! Create a natural habitat for your fish! Mimic their natural habitat! Do so even in your dedicated breeding tank!
Bad grammar though it may be, I use all those exclamation marks to emphasise my belief: If everything in the tank is as natural as possible for a captive habitat, the fish will in turn do exactly what is natural for them. They will pair off naturally and when ready, they will breed. They will do so, because in a nature-mimicking tank the fish are able to relax, as they feel safe and calm in an environment that is literally imprinted in their genes.
This of course means that I am right in the face of another group of fish-keepers!
To all you bare-base tank enthusiasts out there, I understand where you are coming from, but I will never agree with you, except for making one single concession: A bare-base tank is necessary for medicating sick fish, or for a medicated quarantine process. But, as an aquarium? Never! Because if this is the set-up of your choice, you are running your bare-base tanks for your own convenience, but certainly not for the well-being of your fish!
Believe me, it is no more difficult to clean and siphon a properly set-up, well-kept, nature-mimicking aquarium than a bare-base tank! It all boils down just to a little discipline and regular maintenance.
We all already know (or should by now know) that African Rift Lake cichlids require a lot of caves, retreats and hiding spots, that the best substrate for their tanks is plain, well-washed sand, and that the ratio of males to females is of paramount importance.
But there is one further secret to creating a proper habitat that will induce healthy and frequent spawning:  The provision of caves that are never, ever moved, or re-arranged by you, and can never be toppled or under-dug by the tank inhabitants. Trivial though this ‘little detail’ may seem to us, the sense of permanence and security is of paramount importance to a Cichlid seeking to claim a personal territory in which to live, breed  and thrive. 
Yet, consider how you have chosen a home to attain a semblance of permanence, have made sure your ‘back is covered’, and have put security measures into place to protect yourself and your family. Seeking safe shelter is a basic instinct for all living beings. Why should it be difficult to understand that your fish need the same?
Permanent caves are easily made from stones ‘glued’ together with aquarium silicone, taking care to leave only one entry point. Alternately, small clay pots, (extremely ugly in a tank on their own), can be similarly camouflaged with stones and built or ‘glued’ into your rock structure, ensuring that they also offer a ‘view’, so that the fish, while inside or in front of their caves,  do not have to strain to find out what is going on in their habitat.  Make sure that you never move, open or disturb these ‘caves’. They need to imbue a sense of security and permanence in the eyes of the fish.
If you intend to keep Mbunas, your rock-work needs to almost break the surface of the water in your aquarium, while leaving swimming space in front of the rock structures. If you intend to keep  Haplochromis with other Cichlids, you need to plan, in addition to your rock structures, for a lot more swimming space  — as much as you can get. In a Haplochromis only tank, less rock-work will suffice. This does not mean that the rock-work should be any less complex. Because even this species needs retreats and places they can call their own. So even if you aesthetically arrange just a few large and medium boulders on the bottom of the tank, think strategically too : create plenty of caves and retreats, and delineate different territories by arranging your rocks in groups, islands and slopes in different areas of the tank.

Pro-tip: If your Cichlids tend to dig up and re-arrange your carefully constructed aquascape, stop and OBSERVE what they have done. Their need to rearrange your scape means that you have nor perfectly met their needs. Learn to interpret what they have done and why. As soon as your arrangement meets their requirements, they will stop digging and re-scaping!
A Cichlid tank can be as spectacular as a planted aquarium!

THE SUBSTRATE

All Cichlid tanks should have a sand substrate, foremost because this most closely mimics their natural habitat and makes them feel secure. In my opinion, bare-bottom tanks accommodate people, but never the wellbeing of the fish! However, there are many other reasons why a sand substrate is ideal. Many Cichlids naturally feed by grazing through the sand – for example Fossorochromis rostratus, and Placidochromis electra.  Many Cichlids take sand into their mouths and seem to spit it out; however science postulates that some sand is indeed ingested as a dietary aid, as sand is often found in the digestive tract of scientifically examined Cichlids. Also, some Cichlids cleanse their gills by taking in sand and expelling it through their gills, while others dive into, or build their nests in sand. Thirdly, sand is an egg-safe substrate when female mouth-brooders need to pick up and tumble their eggs.
Placidochromis electra, one of the stunning sand-feeding Cichlids
Finally, and contrary to usually uninformed opinion, with sand substrates all detritus is kept at the top of the sand surface. With sufficient tank flow, such detritus tends to keep on moving until the filters can ‘grab’ and remove it. Without sufficient flow, detritus collects in small piles that are easily siphoned off. In a properly administrated tank, chances are that this is very seldom needed. The only other chore is that sand substrates should also be stirred around every two weeks or so, to release any trapped gases. Since Cichlids are notorious diggers that often re-arrange their sand, this becomes almost an automatic task. Any previously dark patches so disturbed will soon return to the natural sand colour. The more regularly this is done, the less the possibility of foul odour emanating from the stirred up sand. 
Ordinary, properly cleaned river-sand is perfectly fine, although no-one is going to stop you if you opt for fancier, more expensive sands! While many aquarists like to use crushed coral to help harden the water and increase its pH, its coarseness traps a lot of debris, just like gravel and is less suited to the sand-feeding habits of this species. In fact, to influence pH at all, crushed coral should be placed in such a way that it is constantly in contact with a continuous water flow — logically making this material a rather silly choice as substrate. Coral sand, while more suitable than crushed coral, is expensive, especially when it comes to larger tanks – in which case a mix of ordinary and coral sand may be a more economic solution. As for influencing the pH, well, you read what I had to say about crushed coral. 

THE LIGHTING

The last important requirement for a Cichlid tank is adequate lighting. There are two routes available here — to inhibit the growth of algae, or to promote it. In my opinion, you should promote algae growth. Not only is it essential for species like the ‘Mbunas’, but most African Cichlids enjoy scraping the algae off the rocks, or picking around in the algae, as algae growth is one of their natural sources of nutrition in their native Lakes. Over time infusoria will become established in the algae, providing further tiny tit-bits to feast on. The rocks in both Lake Malawi and Lake Tanganyika are covered with thick mats of algae called ‘Aufwuchs’ and most cichlids within these Lakes pick and scrape at this mat for the sake of ingesting the algae, as well organisms like paramecium, copepods, rotifers and crustaceans living within. The only way to promote algal growth is via bright lighting!
I you get the essentials right, Cichlid keeping is one of the easiest and most pleasurable aquarium hobbies you can think of! Cichlids are hardy and have amazing personalities which really come to the fore in tanks that mimic nature. That is why we keep them. Should it not also be the reason why you would want to keep them?

Building services engineers design, install and maintain the services that are needed to allow the building to do what it's designed to. These services include heating, lighting, power and supply, lifts and escalators, health and safety, acoustics and security.  
There is a growing emphasis on sustainability and building services engineers are at the cutting-edge of designing, developing and managing new technologies that help to reduce the carbon emissions of a building.
While the role increasingly demands a multidisciplinary approach, some building services engineers choose to specialise in a certain area, such as:
  • electrical engineering;
  • facade engineering;
  • mechanical engineering;
  • public health;
  • sustainable and renewable energy.   

Typical work activities

The role of a building services engineer can vary depending on the specialist area of work and employer. In general though, tasks can include:
  • negotiating and developing project contracts and agreeing these with clients if working in consultancy, and putting out tenders;
  • commissioning, organising and assessing the work of contractors;  
  • working with detailed diagrams, plans and drawings;
  • using specialist computer-aided design (CAD) software and other resources to design the systems required for the project;

AQUASCAPING A PLANTED AQUARIUM

Aquascaping a Planted Aquarium

The simple gathering of plants, beautiful stones and driftwood is no longer the only goal of the modern aquarist. We ‘aquascape’ these days, and not only that — the very practice of aquascaping has become a valued art. It has been made so by the big man from Japan, Takashi Amano, who first introduced the world to natural underwater gardens that looked like dreamscapes.

Whether we create Nature Aquaria in the style of Amano, or not, there is much we can learn from this artistic man’s approach.  Amano’s Nature Aquarium is often misunderstood. It is not the aim of the Nature Aquarium to reproduce nature biotopes of special regions. The goal is to create an underwater landscape that bewitches the viewer and is derived from landscapes seen in real nature. Most of us, when attempting to copy this style for the first time, realised immediately that you cannot really copy anything that has to do with living things, simply because you cannot ever fully copy the infinite feedback loops that nature possesses. Nature is open to everything. In contrast our aquariums are closed systems.
Nevertheless if you set up an aquascape by thinking of a landscape you saw and really liked — whether this may be just an accumulation of stones in the mountains, a little clearing  in a forest, or a romantic river bank on which you once kissed somebody special — once your mind is set on fire, it is as if magic happens: You automatically know which plants to use, or which rocks to collect. You instinctively  ‘feel’ where to place your rocks or driftwood, and you somehow just seem to know how to create some free space which in turn creates a depth of field in your tank.

The Question is: How difficult is it to create an aquarium that looks like those award-winning tanks you see in books or on the internet?

The answer is: It is no more difficult to have a beautiful planted aquarium, or even a Nature Aquarium, than it is to have a normal tank. It is just the careful selection of plants and accessories that makes the difference — and the discipline to effect and maintain it.
At this point, however, I must add a disclaimer:
While I can help you with aquascaping a planted tank, I cannot go into the technical aspects of keeping and maintaining a planted tank here. You must research that separately. You need to know all about the perfect lighting for plants, as they will not grow if you do not have adequate lighting. You also need to know more about the correct soil to, as well as fertilising, as fish poop alone does not deliver enough trace elements and minerals for plants to thrive. And lastly you need to know about CO2 dosing, as this is a main element in maintaining a thriving planted tank. I have recently heard that there is a new bottled product on the market that lets you add CO2 without having to use a doser, but have not had any feedback on its success. That having been said, let’s continue.

If you do not have the confidence to begin, or doubt your inherent artistic abilities, this article is for you. It is meant to be your guide. Follow the guidelines and you will not only achieve your goal — you will soon become an experienced aquascaping artist!

Before we begin, you need to understand that plants AND fishes are equally important in your aquarium, and that by providing the best conditions for your plants to grow, you actually are doing the same for your fishes. When your plants have everything they need to grow well, they simultaneously provide the best conditions for your fishes, as plants use up wastes and excessive nutrients in the water that may cause Nitrate levels to spike, and in return produce oxygen which is indispensable to the life of fishes.
You also need to know that whenever you start a new set-up, your tank needs to cycle before you put in any fish. Granted, there are some wonderfully magic potions these days, that will allow you to almost instantly create an aquarium — and you can use them even when using my method — but some cycling is really better, because it saves you all those problems you are likely to encounter while your tank still struggles to balance itself, potion or not. So ask yourself: Is instant really the best thing for you?
Consider this: Amano, the master of planted tanks, works in exactly the way I encourage you to work, and in the rare instance when he works with an already filled tank, he will not even touch a single plant or rock before the tank he is going to work in is fully cycled!
If you follow my way, you will embrace cycling. With my method, planting is the last task of your aquascaping process, because you will have completed the main part of designing and creating the aquascape well before – and outside of your tank! What is more, instead of experiencing the frustration of waiting aimlessly through the cycling process, you will actually be able to look at a tank full of beautiful plants beginning to settle and grow in — well on its way to becoming a stunning aquarium, and in the meantime will be able to ensure that everything runs perfectly, well before you introduce fish.
However, there are those of you who may like the ‘gardening’ aspect of aquascaping better than the fish-keeping and therefore choose to have a planted tank with no fish at all. With the advent of small tanks,  called nano-tanks, many aquarists have chosen to create several mini aquascapes, instead of just one aquarium, perfecting their technique to almost cult status. Some keep shrimp in them, others simply leave livestock out, and some use this method specifically to display the beauty of the rocks they found. This style is particularly popular in the Orient, as it suits both the Oriental mindset and their acute constraint of living spaces.These tanks are lovingly called ‘The Art of Nature’, and they are truly beautiful. More about them later.
 So let us begin.

Imagination

Imagination is the key to aquascaping. What will your underwater landscape look like? What is the mood you want to create — peaceful and tranquil, or vivacious and bursting with life?  Have you been captured by landscapes in nature? Have you taken a photograph, or stored a picture in your mind? Have you looked at pictures of prize-winning aquariums and found something inspiring to emulate? Or have you found one element in one tank attractive and another element in a second, and would like to combine the two to create a new and unique aquarium?
The question now is: How big does you aquarium need to be to accommodate both the fish you will keep, as well as the scenery in which you will house them?  You need to pay attention to this, long before you venture out to look at plants and accessories. The adult size of the fish you want to keep, as well as the number of species, if you are creating a community tank, will determine how much space you will need. The knock-on effect is that tank-ware like filters and lights are determined by the size of the tank, as well as the fish and plants you will put in. The pro tip here is always to go for a bigger tank if you want to keep many species, or large fish, unless you have space constraints. It is much, much easier to create and maintain water stability in a bigger tank. On the other hand, if you intend to keep tiny species, or just one specific small species of fish, you may well want to consider a nano-tank — or several nano tanks for variety! They can be stunning, and although they need more frequent water changes and top-ups, they require much less maintenance. Once that decision has been made, we can begin our planning phase.

The spine of everything

Although you would perhaps not think so at first, hardscaping, which can be a style in itself,  is also the very spine of most planted tanks. We are talking about rocks and driftwood here – the bones that give your aquascape structure and impact. Hardscape elements lend visual stability and a feeling of permanence, they define fish territories, and provide cover. Rocks and wood can also help you effect changes of level. In addition, they help mask the line where the substrate meets the rear glass, which should never show.
Hardscaping is not just a matter of finding some pretty rocks or driftwood pieces — you need to understand what to look for, and how to make them into the focal point in your tank. So, I urge you to read the article on hardscaping, which actually involves aquascaping without any plant material whatsoever. It is titled “Between a rock and a hard place — Hardscaping your aquarium” and you will find it here . The point of reading this article is that it gives you an in-depth understanding of how we find our materials and then go about composing our aquascape. It would be silly of me to repeat this information when it is already available right here, at a single click of your mouse. I will however repeat the most important tenet of successful design.

The rule of thirds  

We have all heard of the rule of thirds. While slightly different from the Golden Ratio, which was first discovered and realised by the ancient Greeks and has been used in all art forms for thousands of years,  it is a derivative of the Golden Ratio. Not only is it held that this ratio permeates all of organic life, and occurs over and over in nature — but it is a foolproof method we can use to design and arrange elements into an order that is aesthetically pleasing, be it knick-knacks on a coffee table, books in a shelf, or rocks and plants in an aquarium.
The rule of thirds gives us the guidelines on how to place elements with in a design as a way to control where a viewers eyes will travel and what they will see. The rule states that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections.
The idea is that by placing and arranging elements with the rule of thirds in mind will create a more interesting design and that a user’s eyes will flow through the intersections of the grid, thus creating a design that has more energy and tension.
When you’re planning out an aquascape, one of the most important aspects is how and where you want to draw the viewer’s gaze. In fact, the viewer’s gaze is what the aquascape is all about. The primary goal of an aquascape is to be pleasing, relaxing, and interesting to look at for the viewer. To do so, you need to set a sort of “anchor” for the mind. That anchor is called ‘the focal point’. It is the point that draws the gaze of the viewer first, and from where they can then explore the rest of the tank. We use the rule of thirds to establish where to place the focal point and all secondary points of interest.
As we said, the function of the focal point is to draw attention. You have to make it stand out in some way. There are a few simple things to remember about a focal point. The most important is that you should always have some sort of focal point in every aquascape. Not having any does the same as having too many: the viewer’s eyes are left wandering back and forth, stressed and uncomfortable.
Remember, in a small aquarium there should be only one main focal point. Having more than one focal point in a small tank leaves the viewer’s  mind uncomfortable and stressed, looking back and forth from focal point to focal point. In  larger tanks, however, you need to create more than one focal point, and even then one of those should still be the main attraction, while the other points of interest should all be subordinate to it. We use the rule of thirds to do this.

Here’s how it works:

Imagine that there are four lines — two horizontal and two vertical — running through a square of white paper, splitting it into nine equal sections. Wherever the lines cross, is considered a a golden focus point, or ‘sweet spot’ for whatever you want to arrange on it. Let’s use a portrait to demonstrate this.
The rule of thirds is widely encountered among the best works of famous artists and photographers. In fact, several books and articles have been written on this technique. But how do we translate this for the purpose of decorating our aquariums?

This is how:

Imagine again that there are four lines — two horizontal and two vertical — running through the front of your tank, splitting it into nine equal sections. Wherever the lines cross we find the ‘sweet spots’ providing us with a possibility we can consider for placing prominent features like main stones or wood shapes in our aquascape. 
When we use the same method across the top of our tank, we immediately have a layout diagram for the tank floor, telling us exactly where to place our focal point structure/s — on the ‘sweet spots’, of course! 
Once the diagram makes sense to you, it becomes easier to understand that just as we used the same front-of-the-tank rule of thirds diagram both across the top and the front of the tank, we can now also translate the idea further.
We can use the rule of thirds on the front of our tank to plan the height of our ‘main feature’ or ‘focal point’ and then determine how much lower our secondary and possibly a third accent complimentary feature/s or focal point/s  should be.  
We can also take this even further into our over-all plan and choose, for example, to fill about 1/3 of our tank space with our two or three main features together with plants, while leaving 2/3 of our space as ‘negative’ or swimming space – or vice versa. There are almost an infinite number of combinations to play with, and all can help you achieve stunning results.
And once we understand the concept of the rule of thirds, it becomes much easier to see how the backbone of hardscaped rocks are transformed with planting, and how the rule of thirds has been used several times over in the same tank, when we look at the following images.

Planted-tank-rule-of-thirds-main-and-secondary-focal-point
If you thought you were done, think again! The correct placement of our main elements is halfway there, but not enough to give us a successful aquascape!

We also need to create perspective

Creating perspective, or a ‘feeling of depth’, can be one of the greatest challenges in an aquarium, as tanks usually do not have enough depth from front to back to give a true sense of perspective. However, we can achieve the illusion of depth, or perspective,  by how we position the elements of our scape — again using the Rule of Thirds, looking down onto our layout from the top of the tank, as we have demonstrated in the diagram above.
The problem: The most common mistake aquarists make when positioning hardscape elements, is to place their stones or wood in a very unnatural, straight line from left to right. This results in a flat, two-dimensional image. The second most common mistake  is to place only one hardscape element in the tank, if it is a larger, rectangular tank.
The solution: To avoid this, look at the diagram again, as if looking down into your tank. You can see where the suggested ‘sweet spots’ are. But now also imagine your layout as a whole consisting of several images, or slices, layered one after the other from the front to the back of the tank, each with a small gap in between, so that each image is slightly further away from the  front of the tank. (Imagine building a sandwich, layer by layer, from the front to the back of your tank) This means that wherever you place hardscape elements, and later your plants, as long as they are in different layers or slices, they will span a variety of points across the depth of your tank.
While some pieces of hardscape and plants can share the same ‘slice’, or point of depth, the key is to create more slices that just the one required for your focal  point. For example, begin at the front of the tank, where the slice and what it contains should be lowest, in the next layer growing higher, in the next even higher, until you reach the back of the tank, where they will finally be the highest. But this is just one example. You may not want to have the highest point at the back of the tank, but rather on one of the sweet spots, leaving swimming space for your fish towards the back of the tank. Thinking in layers is just like the rule of thirds — simply a guide to creating a good sense of perspective within the aquarium. The images below demonstrate this principle, and the impact it has, perfectly. It is also quite interesting to know that these aquascapes have been done in small tanks — the lower one in just a 25 litre tank!
Planted-tank-Perspective-created-with-layers
This is a brilliant example of layering from front to back to achieve perspective. See how the low front introduces us, but then leads the eye to the highest focal point at the back left, resting only briefly on the the medium height planting, which so artfully helps adding to the overall illusion of scene depth.

aquascaping-layering-for-perspective
Another brilliant aquascape depth illusion! The arrangement draws us in – almost urging us to climb to the very back back to see what lies beyond.
When it comes to creating the illusion of depth, one of the most spectacular aquascapes is the one below – all illusion, but very, very skillfully done! It has been created by Cliff Hui of China, an aquascaper that has become famous for the detail he pays to his creations. Note the tremendous amount of attention that has been given to making this illusion seem true, by leading the eye towards the seemingly un-ending horizon and note how a certain amount of unordered ‘wildness’ helps add to the ‘feeling’ of the depth.

In this case the focal point is close to the front, while a patch leads us toward the infinite horizon.


Also note how the rule of thirds comes into play: one third of this scape is filled with attention grabbing elements, two thirds contains very little, creating that wonderful illusion of depth and airiness!
There are a few more tricks you can consider to help you create depth. Consider creating different levels. You could plan, for example, to slope your substrate, so that the foreground is much lower than the background. Or, slope from left and right, creating a valley in the middle. Artfully done, slopes are a great tool for adding depth.
More controversial, and therefore seldom chosen, you could consider simulating depth by placing larger items toward the front, and smaller items toward the back. If this is skilfully done, the scape gives the effect of depth because as everything gets smaller it, it seems to recede into the far back distance.  In this case you must also consider the leave sizes of your plants! Various sizes of Anubias can be great for achieving this effect. In the image below, driftwood was used to create a forest feel. The ‘tree trunks’ in the front were heavily planted at the base and appear larger than those seen further back. This gives the viewer the illusion of being drawn in to wander through the ‘forest’. Can you see how the rule of thirds was used for the placement of the ‘trees’?
It helps to keep your foreground layer fairly shallow – not in substrate depth, but in terms of front to back depth. Having a huge foreground compresses the mid-ground and background, and takes away space from transitioning between them. Finally, when you get a chance to position your hardscape elements, you will have to make sure that once planted, there will be clear lines for the eye to follow from front to back. For this you need to pay special attention to ensure that the foreground naturally transitions to the mid-ground, and then from there to the background.
And then again, if you are a rebel, you may want to break all the rules!  Can your tank be a success without following rules slavishly? Of course, if you have an innate sense of design, as the tank below demonstrates.
Once you have established where the ‘bones’ of your future aquascape are going to be positioned, and how high they should be, it becomes much easier to judge what rocks, or wood you will need for your hardscaping and you can begin hunting in earnest for the perfect pieces. Forget about the plants you will need. That comes a little later — after we have done a ‘dry run’ outside of your tank.

HUNTING FOR ROCKS AND WOOD

Instead, as you hunt for your rock or wood, ponder upon this: It is much more important to use different sizes of the same type of rock or wood, than to take just one very beautiful piece. One single stone in a tank always looks artificial. So does a single piece of wood. Nature will quickly tell you to place at least two, and preferably more. In fact, for some bizarre reason arrangements always look better if they are made up of uneven numbers, irrespective of whether they are rock, or flowers, or fruit in a bowl.
The biggest piece of rock (if really big enough) will be the main focal point. If you cannot find a piece that is big or important enough, you may have to look for two or three pieces with matching strata or grain that you can glue together to give you more ‘bulk’.
The second piece should be smaller, but still of the same kind, because it becomes the harmonious complimentary counterpoint for the big focal piece. Also look for a third piece or a grouping of pieces even smaller, and perhaps a little flatter that the secondary focal point, which would look good when placed closer to the front of the tank, almost like a little accent to echo the other pieces. Not only will this allow you to arrange three distinct points into a rough triangle, it will become a major part of the trick we call leading the eye.

COMPOSITION

Many aquascaping articles on the internet at this stage throw composition possibilities at you, talking of U-shaped, triangular and convex arrangements. I will not do that, because it is like painting with numbers and I do not want you to create yet another same-old-same-old aquarium! There are too many of them around. Where is the fun and personal creativity in that? Consider my method instead — because my goal is to pull the hidden creativity you have to the foreground and let you scape a perfectly individual aquarium. Have confidence, because if you follow the basic rules, it is really impossible to aquascape a mediocre or ugly tank.

 

BUILDING YOUR AQUASCAPE

So, at this stage, when you have all you hardscaping elements collected, you should be ready to begin constructing your structural layout OUTSIDE of the aquarium. Mimic your tank floor and back wall with cardboard, or Styrofoam, cut to the correct dimensions of your actual tank. Use a table on which to do this, as it gives you a better visual point of view. Mark out your rule of thirds grid on the floor and decide on your sweet spots.
Now is the time to begin constructing the bones of your aquascape and experimenting with various possibilities. But before you do, heed this warning: Balanced is Unbalanced. While we in the aquarium hobby always strive for balance in our systems, this pertains to our water parameters. In aquascaping ‘balance’ or symmetry is not natural. Nature makes it abundantly clear that non-symmetry rules, and that it is beautiful. Don’t space the elements in your aquatic environment evenly. Use your rule of thirds grid! And when you group elements, use uneven numbers — 1, 3, 5, or 7.
To demonstrate, I have a story. I once wanted to create a woodland effect in my garden, with bulb plants popping up and creeping out of the lawn in spring. Instead of ‘calculating’ where I would plant the bulbs – it never looked natural to me, whatever I tried – I simply decided to  ’pour’ the bulbs out of the bag on to the lawn, letting them fall where they wanted. That is where I planted them! The effect, once my bulbs burst into bloom was not only stunning, but very, very natural. You may want to try that with your individual rocks, to see how they naturally fall; at the very least the fall will disclose the ‘balance’ of the individual rocks!
Instead of symmetry, rather pursue ‘harmony’ — or if this makes it easier to understand, tell a story. This is really a worthy quality to strive for. Whether your goal is a bio-typical slice of real habitat, or some other-worldly vision, the arrangement you create can and should be an attempt at telling a complete story, or making a discernible statement.
So, let us commence! Begin by placing your main element. Is it high enough or do you need to elevate it with a base? Remember, this is the main focal point. It is supposed to draw your attention, and it should in 90% of cases actually dwarf your future inhabitants. Besides, that base could be hidden by your substrate. In fact, rocks effectively look more natural if they are bedded in the substrate. So when you use a base, keep the height of your substrate levels in mind. When you are done, place your second focal point, more-or-less around the second complimentary sweet spot you chose. Check for height. You want something around 1/3rd lower that your main focal point. Again adjust the height with a base if necessary. Now see if you want to place a third, even lower element towards the front of the tank, forming roughly a ‘skewed’ triangle with the other two? Do so now. Check height and keep future levels in mind. Then stop! Don’t go any further before you have not looked the arrangement in its totality. You should already get a feeling of harmony. Pay particular attention to how much of the upwards space of your aquarium you used: I am referring here to the space between the floor and the future water surface of your aquarium! Many tanks miss the mark because that space has not been used to its full potential! Don’t create an aquascape that leaves your tank only half filled! It will look and feel unbalanced and stingy. 
I want to make another particular point here, and it is this: If you have placed your stones properly in your aquascape arrangement, the rest of the scape, as if by magic, will lay itself out for you.  You will know it the second this happens for you. It is as if the moment you attain a harmony and balance in your placement, everything else is drawn towards and wants to become part of that balanced harmony.

The two images below demonstrate what happens when you set your stones correctly! The Rockwork in this nano-tank is absolutely brilliant! And just as an aside, while the  second image shows the aquascape planted, it is also clear that some growing – and pruning –  must still occur. But all-in-all, the plants nestle between and against the rocks in a very natural way.
So stand back and ask yourself: Do I want to tilt my rocks? (If you do, you need to stick to this same tilt throughout!) Do I want different levels? Would terraces make my scape more interesting, or more dynamic? Will I have to shore up substrate when I get to that stage? What colour substrate will look best with my arrangement? (After all a black substrate would seem discordant with pale rocks) What do I need to do with the back wall of my aquarium? Paint it? What colour? Which plants will work best? Where will my highest plants go? After all, It would be silly to plant a tall sword plant next to my main focal point if its stone  is supposed to simulate a mountain! What will show off my plants best? Do my eyes get led from front to back in a natural way? If not, how will I change my arrangement? Will my foreground hardscape element/s be tall enough once my carpeting plants take off?  What else do I need to add to make this arrangement better? Or, do I actually need to take something away to make it better?
You must by now be able to see the sense in my method of building the scape structure outside of the tank. What if you need to make a drastic change, or find a new or additional piece? How can you choose a substrate, or the size of your substrate, or for that matter, a background, before you know for certain what you are going to do?
If you were working inside an already established, or filled aquarium you would not only be dripping water all over the place, you would be cursing, or crying with frustration! And the more you stress, the more mistakes will you make! You can avoid all of this agony by being a little patient and doing things the right way! If you already have an aquarium and wish to re-scape, do yourself a favour and temporarily re-home your fish in a spare tank, together with your heaters and filters with their filter medium, so that you keep your good bacteria alive.  Empty and clean your tank, and then begin to work as you really should!
So back to the design. Simply back off, observe, and do what needs to be done to rectify things if they were not right. Get what you need. Glue, or putty pieces together if needs be. Think about how you will hide, or disguise your tank-ware once you actually start to build inside your aquarium.
Do not be discouraged. We have help at the tips of our fingers. I am not asking you to act upon these principles — at least not yet. All I want is for you to read and absorb the ideas because some of them will stand out, or inspire you, and some will inevitably lead you towards decisions you may not even have considered before.

 This is what our professionals says about Principles:

1. Plant all groups in odd numbers.
2. Fine leaved plants look best in the mid to back centre of a tank, with heavier leaved plants toward the edges.
3. Don’t use red in the middle as they have a heavy, dark, feel.
4. Dark leaves (red or dark green) look best toward back edges, with light coloured leaves toward the centre.
5. Arrange plants and hardscape (rocks and wood) to provide good contrast of light and dark areas.
6. Light coloured sand provides good contrast to plants.
7. When rocks are used, use multiple sizes, mixing large and small rocks, as in nature.
8. Rock edges should generally be rounded.
10. Hide your intentions with rocks. Allow plants to obscure them to some extent, sometimes maybe even completely.
11. Aquascapes with unplanted sand in front is a good alternative to the traditional “Nature Aquarium” style of all foreground covered with foreground plants.
12. An attractive layout alternative is a slope up from near the middle up to the two back corners.

And this is what they says about Technique: 

1.Use cotton thread to attach Java moss to wood, or lava rocks.
2. Moss on rocks is great for edge work, blending an open sandy area into a planted area.
3. Use driftwood with moss, or large moss rocks, as something for background to grow over and cast shadows for good dark/light contrast areas.
4. Wrap Anubias onto moss covered rocks using a plastic ties, and trim off almost all roots, for “rocked Anubias”.
5. A rocked Anubias can be set right on sand, or moved around as desired. But initially face it slightly forward to hide its roots. Later it will grow upward toward the light.
6. Plan on putting crypts (underwater heating) only in places with deep substrate.
7. Use stem plants in even lengths with graduated height sets, descending from high to low, as the sets move toward the front or middle of the tank.
8. Plant stems 2 or 3 at a time, in the same hole.
9. A new tank should not be trimmed for 3 months.
10. On first trimming, let stem plants grow to the top, and then trim to halfway point.
11. Anubias and moss make great foreground plants as they take no trimming.
12. Putting tubing and/or wires that come into, or out of, the tank on the side makes it less visible to straight on viewing due to a “mirror” effect from side reflections.
13. Creating a substrate with separate sand vs. soil areas can be accommodated by placing cardboard in the tanks where you want the boundaries between the two, and slowly filling in both sides until full. After adjusting any slope you might want in the sand or soil, and making sure that both sides are at the same height where they touch either side of the cardboard, the cardboard can be gently removed.
14. Sloping substrate from front to back works better if something like drift wood is placed in the middle of the slope to keep substrate from moving forward. Moss rocks also make a nice barrier if placed to serve the same purpose.
15. If a substrate of separated soil and sand is used, driftwood and/or rocks can be placed on the line between the two to cover or hide the separation point.
16. Light shining up from the back bottom looks great! And it will light any ripples on the surface from an angle beneath, highlighting them.
17. For a really simple landscape, use mossed pebbles around big central rocks.
18. A fully mossed group of interwoven driftwood branches looks wonderful when it fills in. It will look almost solid, and if done correctly can give a sloping look from lower front to upper back, possibly also sloping low and toward the middle, and up toward back corners.
Wow, the mind literally reels. In just this short read I have found several points that are literally making me drool to start a new aquascape! I hope it has given you ideas too!

Pro tip:

There are different ways to treat your tank background.  In “Nature Aquariums” you seldom see tank backgrounds. This only works if you can afford the very modern, streamlined tanks. For most of us, a background is a necessity. Some people use cork, others wood, some paint the background and some use self adhesive foliage scenes (not my first choice!). Yet there is a very neat trick that actually makes a tank look very deep. It is attained by using an adhesive film with a frosted effect (that looks like sandblasting) to the outside of the aquarium back wall. This is a decorative material (registered brand DC Fix) and can be found at places that sell materials for home improvement.
 In every other case it is unnatural to see the wall with all the hoses and cables shining through the glass. If you paint, blue and black are the best colours, as this gives your tank a wonderful contrast and yet, somehow also causes it to disappear, making it easy for any viewer to concentrate on the aquascape and its inhabitants. 
When you have made all the adjustments and completed your hardscape on your table, and you have chosen and bought the substrate you need (both decorative and soil) and all glues, putties and silicone stick-togethers have had 48 hours to properly cure, you are ready to work in your actual aquarium. It is time to get your plants too, and that should now be an easy task, because the visual input from your out-of-tank scape would have given you a very good idea of what you will need.
We now come to the only difference between scaping a hardscape and creating a planted tank. For a planted tank you usually need to put your substrate into the aquarium first. The only time you must deviate from this course is if you are using large rocks and you want them to be partially embedded into the substrate — or if you need to place your rocks as barrier,  to keep different levels of substrate from collapsing forward!
As you are planning to have plants grow in this medium, it needs to be a substrate specifically designed for planted tanks. At this stage you will begin creating some levels, by shoring up. If you have not done so before, you now need to begin to transfer your pre-built hardscape into your aquarium, focal point by focal point, placing them in the tank exactly as they had been arranged on the table. It could not be easier!

Pro tip:

Please note that if you have a large aquarium and wish to transfer any heavy rocks into your tank, you should rather opt for the bare-base placement method. The  bottom of your tank should be clean and you should have cut pieces of Styrofoam sheeting, or egg-crate to go beneath the heavy rocks, to cushion them from the glass. It is not the weight of the stones that crack aquarium floors, but the weight of the rocks concentrated on a few sand grains. This does not pertain to drift wood, unless you have a very large and heavy piece of wood.
In this case your substrate filling and shoring follows after the rock placement. One useful method is by placing hidden plastic pieces in such a way that they keep the soil from sliding forward, as in the riverbank aquascape demonstration below.
Hardscaping-shoring-up
Once that is done, it is time to plant. Note that we still have no water in the tank! Instead you will have an ordinary garden spray bottle ready, and with this mist the plants and the substrate from time to time.


As for planting order, it is best to begin at or around your main focal point. Always look to nature to see how grass grows around stones and how moss grows around roots. Nature is the perfect teacher. Emulate that! Decide whether you want to emphasise the rock, or partially hide it. Then do the low growers, then the mid-growers and right at the end the high plants.
Always plant very densely. It is more expensive at first, but oh, so gratifying in the long run!
Stem plants are an especially good way to add form to your aquascape. Many small leaved species, such as micranthemum micranthemoides, m. umbrosum, mayaca sellowiana, or rotala indica to just name a few, can easily be trimmed to a desired shape. That is the reason you have to plant these species quite densely. Take two to three stems and use tweezers to place them in one hole. Repeat about 2 cm beside this, and so on. The more densely you plant in the beginning, the faster the tank will grow in. This is especially important considering that in the initial stage, when it becomes to cut the tops, you will be able to replant the cuttings between the parent stems while you leave the rooted parts of the parent plants in the substrate. Propagation is where you begin saving money, and the rooted parts will bud new shoots within short time!
It is wise to use plants with different leave sizes and/or colours. This helps you create more depth and texture and adds to the natural feel. The smaller your tank is, the smaller must the leaves of your plants be, as that helps to create the illusion that your tank is larger than it actually is.
Red plants do really stand our and can help you with contrast — but do be aware they can inadvertently become yet another focal point, and distract the eye from that special focal point you so carefully chose. As i points out, their darker, heavier feel makes them more suited to the back or edges of your scape.
Once you have planted, it is time to fill your tank. There is a special way to do this: Scrunch up several sheets of newspaper and place them over the finished planting until it is completely covered. Wet the newspaper down with the garden spray. Next place a large sheet of thin plastic (the kind dry-cleaners place over coats and dresses) over the newspaper and ensure all of the surface area is covered. Then slowly fill the tank with a hose ensuring that the flow falls very gently onto the central part of the plastic sheet. When the tank is full, very  gently remove the plastic sheeting, and then the newspaper. You will be surprised at just how effective this can be, leaving your plants, substrate and aqua scape just as you intended. What is more, you will have almost perfectly clear water!
Once filled, cycled your tank. Do not add fishes yet. You need some time for your plants to adjust, take root and settle into their new lighting conditions. You also need to let your water gradually move into its own balance. Over-hasty dosing with chemicals and buffering potions often lead to wildly fluctuating water parameters when you add fish too soon.
Give the nature you brought into your tank via you plants a chance to work. Watch your tank carefully over this time, in case there is a sudden algal bloom. This is usually caused by too much light (or if you added fish anyway, a sudden nitrate spike). The easiest, and in my experience the most natural way to stop algae in its tracks is to temporarily add floating plants to the tank — lots of them. Floating plants shade your tank and deprives the algae of the bright light they need to flourish,  and they will also sop up the nitrates, if you added fish. You will remove them again once your tank has stabilised. But for the time being, do it in such a way that you do not filter too much light from the plants below, as you still want enough light for your plants to photosynthesise.
Finally, when the time comes to add fish, do so slowly. To keep the beauty of your aquascape intact, you must choose your fish inhabitants very carefully. Nature Aquarium adherents usually choose schools of small fishes like tetras or rasboras, because these make their tanks appear much bigger. Think of your tank size and of proportion. Do not choose species that dig, or species that will outgrow the scale of your aquascape. Do a lot of research about this!

What happens if you do not want hardscaping in your plated tank?

Having said all of the above, I am left with explaining to those of you who do not wish to have any hardscape in your tanks, that plants can be used to execute the same design principles. In your case, you would create your focal points with groupings of suitable plants, so that the height levels and placement planes change, just as they do with hardscape elements. You need to be very careful though, because it is very easy to lose your way and end up with an incorrectly planted  ’Dutch’ style tank. On the other hand, if you do want to do a Dutch planted tank, you need to research the rules of ‘Dutch’ style aquascaping, as they differ significantly from other planted aquariums. See if you can see the difference between a panted tank and a Dutch planted tank below.

I thank you for your patience in reading through all of this article. We are almost done. I know I have given you a lot of material to absorb, but at least it is all in one place and you do not have to scrabble around on the internet. 


Maintenance!

Setting up an aquascape is one thing, but maintaining and enhancing its beauty is completely different. Only regular pruning and water changing, as well as getting the right balance of nutrients, lights and CO2 will allow you to achieve your goal. A word of caution though: To begin with, do not light your tank to its brightest capacity. You would be courting algae if you did! Let your plants settle and gain a foothold. Then slowly heighten the brightness until you reach optimum.
Frequent water changes are extremely important with a freshly  planted aquarium set-up. Start on day 3 after set-up with a 20% water change. Repeat this every 3-4 days for the  next 3-4 weeks. Do not use water that is too warm or too cold. A temperature around 20-22 C is  best for changes in planted aquariums.
Sometimes, once your plants grow in, you may even have to change a group of plants, because they do not look like you imagined they would. But maintenance is an integral part of the aquarium hobby, and it will be infinitely more pleasurable if you just accept this as spending time with your pride and joy, rather than a chore.

SITE ENGINEERS DUTIES AND RESPONSIBILITIES

Site engineers perform a technical, organisational and supervisory role on construction projects, setting out and determining the location for above and underground infrastructural installations involved in construction operations.
Site engineers apply designs and plans to mark out the site and can be involved in projects ranging from small scale to multi-million pound ventures. This may include civil, road, rail and other infrastructure projects.
A site engineer works as part of the site management team liaising with and working alongside architects, engineers, construction managers, supervisors, planners, surveyors and subcontractors. They share responsibility for site security, health and safety, and the organisation and supervision of material and human resources.

Typical work activities

Work activities vary depending on the type of employers and nature of the project but typically involve:
  • acting as the main technical adviser on a construction site for subcontractors, crafts people and operatives;
  • setting out, levelling and surveying the site;

KOI

KOI

Commonly called Koi in the western world, and originating from the common carp, Cyprinus carpio,  the name “Koi” comes from Japanese and simply means “carp”. In reality the name Koi thus includes both the dull grey food fish as well as the brightly colored ornamental varieties.
The correct name for the beautiful ornamental carp is Nishikigoi – a name that literally and very descriptively means “brocaded carp”. If you wish to become an afficionado of this fish, it would be wise to learn and use the correct term, as Nishikigoi were developed in Japan and the language of the koi world, or more correctly the Nishikigoi world, is and will remain Japanese. Japanese is used not only to name the varieties, but also for many of the terms used to describe the colours and traits of these beautiful fish.
As an aside, in Japanese koi is a homophone for another word that means “affection” or “love”; koi are, therefore, symbols of love and friendship in Japan. The koi is also an often recurring symbol in Irezumi, the Japanese art of traditional tattooing.
Nishikigoi (or Koi) varieties are distinguished by coloration, patterning, and scalation. Some of the major colors are white, black, red, yellow, blue, and cream. The most popular category of koi is the Gosanke, which is made up of the Kohaku, Taisho Sanshoku, and Showa Sanshoku varieties.
The earliest types of Koi produced were bred from the fish kept as food by rice farmers, to supplement their winter diet. From time to time coloured mutations would appear amongst these carp and some were kept as pets. It seems most likely that the first types to appear were the red and white varieties now referred to as Kohaku. From these early beginnings breeders were able to breed other colour varieties. The next types to appear were Sanke and Showa, both with three colour patterns of red, white and black, but with different proportions of the three colours.
In 1904,during the Japanese-Russo war, the Munich Research institute for Fisheries in Germany gave 40 western carp to the breeders in Japan. Sadly only 1 Mirror Carp and 6 Leather Carp survived the trip. Nevertheless, these German Carp were immediately introduced into the Japanese breeding programs and cross-bred with their indigenous carp. These seven Doitsu carp turned out to be the genetic backbone of Doitsu carp and later the Doitsu koi as we know them today.
Initially the Doitsu carp were only used to enhance the production of edible fish and not to create ornamental koi. The newly introduced German carp did not have scales and was easy to clean and prepared for food.  But unlike what many people believe,  the main reason for the introduction of the German carp into the food market was the bulkier body shape and thus more meat to eat. The hybrid vigor caused by the cross breeding of Doitsu and Japanese carp was a major contributing factor in producing more fish meat. In addition, the Doitsu carp grew remarkably well and outperformed the local carp.
It was only at a later stage that the German carp was actively used to enhance the ornamental koi carp – and what a large contribution they made to the selective breeding of Nishikigoi. In 1906,  a new strain called Doitsu-Asagi came into being.  Kagami Uroko, or mirror scales is a characteristic feature of German carp. Kagami Uroko not only dominated the scales of Nishikigoi, the German carp were also much easier to take care of than their Japanese counterparts. It is thus that ease of care became a trait carried forward to today’s modern ornamental carp.
The most obvious difference was the scalation on the newly produced koi. Less obvious but as important were the body shape changes that took place. The long and much thinner body conformation of the Japanese koi changed to the beautiful bodies of modern koi. Almost all koi varieties today do have Doitsugoi blood in their genetic makeup. In fact, the superb body shapes off modern show winners would not be possible without the genetics inherited from the Doitsu carp.
Japanese recognize thirteen basic classes of Nishikigoi, or Koi and these classes are now accepted throughout the world. Within each of these classes there are a number of sub categories. We cover these in the images below.

IN THE AQUARIUM

Koi are not suited to aquariums, except when they are very small. Even then it is recommended that they be kept in a proper Koi pond.

BREEDING

Nishikigoi , or Koi do not breed true! So, having a pair of expensive show champions means that out of 20,000 eggs only 10 will grow in to that coveted perfect fish.  But that does not stop the breeders trying to perfect the species. New koi varieties are still being actively developed. Ghost koi developed in the 1980s are a hybrid of wild carp and Ogon koi, have become very popular, and are distinguished by their metallic scales. Butterfly koi, also known as long-fin koi, or dragon carp, were also developed in the 1980s, and are notable for their long and flowing fins. They are hybrids of koi with Asian carp. However, there are those who do not consider Butterfly and Ghost koi to be true Nishikigoi.
With so many Koi being bred today, quite often a totally new combination is found – and those combinations may not fit in any of the thirteen categories. As they become more popular, some of these unique Koi will eventually become consistent enough for their features to form a new category. So, keep your eye on the breeders.
The beauty of Nishikigoi truly deserves the accolade “Living Jewels”. We hope that you discover much more by studying the images and information below, and we wish you joy with your Nishikigoi!
Finally, we have this advice for novice koi hobbyists: Do not get daunted by the flurry of Japanese terms corresponding to the various breeds of this fish. Get accustomed to the terms slowly, and enjoy the learning process. The best starting point of this learning process is more often than not with the three most established and most popular breeds of koi, namely the ‘Kohaku’, the ‘Sanke’, and the ‘Showa’. ’Gosanke’ is the term used to refer to these three breeds taken together. Talk often to other Koi enthusiasts – and if you can, ask breeders to point you in the right direction. They recognise the potential of baby Koi very early on! The more you hear these terms, and the more you watch what other hobbyists do, the sooner those bewildering koi terms will become part of your everyday vocabulary!
