The sight and sound of water has a very soothing and calming effect and adds to the beauty of a garden. Building a pond is a complex and time-consuming operation. The first step towards building a pond is to decide what kind of pond you want. Do you want a koi fish pond or a goldfish pond with aquatic plants? Do you want a want to use pond liners or a pre-formed pond? How big a pond do you want?
The next step in building a pond is to analyze the topography of the space to decide the location of the pond. Are there rocks, trees or any soil conditions to consider? Can these be removed or worked into the garden landscape? Once that is decided, you need to lay down the shape and dimension of the pond. For example, a garden pond for water lilies or goldfish needs to be only about two feet deep while a koi fish pond will need to be three feet or deeper because koi fish are larger fish and need enough space. The pond will then be dug to the desired shape and a shelf around one foot deep and wide dug around the perimeter of the pond. The pond could have more than one levels or just slope gently.
There are two kinds of pond liners – hard pond liners and flexible pond liners. Pond liners are usually made of butyl or PVC. After excavation, any lumps or stones are removed from the hole. Then a one inch layer of soft sand is spread over the area. This helps protect the pond liner from being torn or punctured. The liner is then spread over the pond hole and spread evenly so that wrinkles and folds are minimized. The liner edges are secured and held down on the edges of the pond with bricks or stones. Water is then poured into the pond slowly until it fills up. Pond pumps and filters are then fixed in place. Pond pumps and filters are important to ensure proper circulation of clean water in the pond. Pond filters remove organic debris from the water and clean it before it returns to the pond. Good pond filters prevent the water from going green with algae formation and ensure the healthy survival of marine life like fish. There are different varieties of pond filters and pond filtration system to suit different sizes of ponds. Garden pond pumps come in many sizes and ratings according to the rate of flow required. Garden pond pumps will ensure that the right volume of water is being pumped through the pond filters or filtration system.
The last step towards building a pond is to add aquatic plants in and around the pond. Aquatic plants do not just add to the beauty and feel of the garden pond but are also vital to the health of the whole pond ecosystem. There are four kinds of aquatic plants. - water lilies or lotuses, marginals or bog plants, floating plants like water hyacinths and oxygenator plants. Fish may be introduced into the pond after six to eight weeks after the plants are established.
