Building Your First Koi Pond
A well built garden pond is relaxing and creates a feeling of coolness and mystery. You can design and create the perfect garden environment with water by building your own garden pond. You can allow your imagination complete freedom to build a koi pond that looks attractive while still being functional. Koi ponds should be at least 4 feet deep. This insures the koi’s habitat will remain frost-free even in the depths of winter.
One option is a preformed pond made of plastic which are very simple and fast to install and they’re available in a range of sizes and shapes. But are of fixed designs. Another option is using a rubber pond liner allowing you free scope. When designing a pond with liners you can put your own ideas for a pond into practice.
Here is outlined plans for a lined pond 10 square metres in size. Once you have drawn out the plan for the shape of the pond you are ready to start. First of all, mark out the basic outline shape by sprinkling sand on the ground in the shape desired. You could also use a rubber hose or string. Use a spirit level to check height differences in the ground. If there are differences in height in the ground, lower levels have to be built, while higher levels will have to be lowered by removing soil. Once the outside boundary of the pond is level we can start digging.
The pond must be dug from the outside inwards. Remove protruding stones and roots that you will find as you dig. Dig out the whole pond area to the depth of the shallows. You then have to mark the bog zone, the shallow water zone and the deepwater zone. Use some of the Earth dug out to create the slope for a stream. the size of the liner required is calculated using lengths of string. Lay these out along the length and width and after adding on an extra 50 centimetres on each side you can work out the exact measurements for the liner.
The edges of the pond can be created in a number of different ways. The simplest method is to make a trench all round. Fleece and liner are laid over the mound so created and then tucked in. The gap produced is filled up with gravel. However edge fixings systems built on a firm base ensure that the edges of the pond do not sink even under load. Whether you use stone, wood or plastic tubing there is a whole range of options open to you. This design is with plastic tubes. If there are too many protruding stones in the earth the bottom of the pond you can cover it with a layer of sand to protect the liner. However, normally a. fleece is sufficient for lining the pond. Press the fleece firmly into place and cut off any surplus material. The next step is the pond liner. The decisive Factor is its texture as well as a high resistance to tearing. A rough texture of you liner makes it easier for microorganisms to attach themselves. This soon gives the liner a natural appearance
For the edges you can use a liner with a decorative stone pattern. Pump hoses and cables are tucked away out of sight in a fold in the liner. Otherwise there should not be any folds or creases in the liner if possible. The liner for the stream is bonded to the pond liner with glue. Lastly you can form the protruding liner into a fold 10 centimetres deep. This so-called capillary barrier prevents the surrounding earth becoming saturated with pond water. The plants are placed in planting baskets which we fill with substrate. First of all we plant the deepwater zone where the pump is also located. This entire area is decorated with stones. However the stones should not be within the suction zone as the pumps performance will be reduced by a smaller suction area. High quality pumps are available whatever the application or requirements. If the pump becomes blocked up with leaves or Grass just blast a jet of water from a hose and pick off any remaining debris. There is a wide selection of special pumps for water features of all kinds. You can also attach a skimmer to your pump to clean the surface. The skimmer removes dirt and leaves directly from the surface of the water and passes them to the filter. Place gravel at the bottom of the pond and use large stones to set your pump and filter in position. Then fill the pond using tap water. Then plant the shallow water zone with potted plants.
Embankment pockets are a perfect solution for the steep bank they are fixed with large stones at the edge of the bank and covered with gravel. To plant the bog zone cut out embankment mats from coconut fibre and arrange them in the shallow water. The mats are a lastly weighted down. Finally the bog zone is filled with gravel. Let your imagination run free when creating the transition from Pond to garden. This design is for natural stone paving. At this area on the bank any animals that fall in the pond can climb out again. At this point, the pond already looks really good. Your aim is to create a clean and healthy pond. A good option for filtering a pond is based on biological filtration which filter dirt and surplus nutrients from the pond water according to a mechanical biological principle. How does a biological flow filter work? Pond water and dirt are fed to the filter by the pump. In the filter there are filter material where bacteria grows. This bacteria breaks down the fish waste matter into harmless nitrates. Also available are ultraviolet light filter attachments that kill off algae and excess bacteria.
Filters will clog up regularly so buy a filtration system that is easy to clean.
To add a small stream to the pond you need a pump with pressure filter that can power the filter and still have power to raise water to the stream.
Now you are ready to start adding the fish. But you first have to wait a couple of weeks for the water to mature. It’s the fish that really make the pond come alive. You caould mature your pond and filter with some cheap goldfish before you buy your prized koi.
The basic stocking rule applies; you should never stock more than one kilogram of fish per cubic metre of water in your pond. Your pond will hold 6000 litres that’s a maximum of 6 kilos of fish. But don’t forget that fish will grow so if you are buying young fish then the limit your pond to a total weight of 3 kilos per cubic meter. Then wait four weeks before stocking your pond with koi. that is the time it takes for the bacteria in the filter to mature. And then only add 1 or 2 fish at a time over many weeks.
It is a very good idea to buy a water test kit that tests the water for ammonia and nitrites. Test the water and only when these readings are near zero can you add the next couple of fish.
Clean water, thriving plants and happy Fish is your goal. You should by now have a fascinating piece of nature in your own garden. Making your own pond is really simple. Building a pond is not difficult with using your ideas and the right equipment.
Water features also give your pond something special. A range of different effects can be achieved really easily in next to no time. A waterfall can be built using a build up of soil covered in pond liner and edged with rocks and plants. You will have to use a pump to take water from your pond to the top of the waterfall. Hiding the end of the pipe between stones or plants will create a more natural effect.
To make sure your fish are happy in their environment buy quality koi specific foods. The result is something to be proud of. A healthy easily digestible diet will keep your fish active. Tame fish even eat out of your hand. The ideal koi food will contain ingredients like spirulina and carotene. These are color enhancing foods that work very well to bring out vibrant colors in your koi. However, overuse of these products may result in the white areas of the fish developing an orange or yellow cast. To maintain brilliant white areas reduce the amount of color enhancing foods used.
Plants produce oxygen and reduce the level of nutrients so curb the growth of algae. Every plant in your pond has its preferred location. Waterlilies love deep calm Water. Reeds and Rushes on the other hand, prefer shallow water. Once your pond is build it needs occasional care along with its inhabitants.
And with the right tools it is simple to look after your pond both in and at the edge of the water. Whatever decorative idea for your pond interests you, if the technology keeps a low profile a truly natural atmosphere will be the result. Ponds can also look really attractive in the dark. Lighting systems can conjure up fascinating moods.
