Pond Filters – There is more to building a Koi pond than just digging a hole in your backyard and filling it with water. And while the idea of spending hours enjoying a private paradise at home is very interesting, attention must be given to helping prevent this dream from becoming a nightmare. Unlike the swimming pool, which can be easily maintained by adding chlorine, the backyard fish pond is its own ecosystem. Without persistent freshwater sources, this environment must be maintained to ensure healthy water for Koi and other fish ponds.
There are several important areas to consider when designing backyard water features. Arguably, the most important factor of this is pool screening. The appropriate collection filters function for important roles. The first role, mechanical filtration, involves removing waste from fish, leaves and other debris from pond water. Without filters, these debris will quickly begin to deteriorate in the pond and produce poor water quality. This poor water quality will then cause parasites, fish diseases, and in extreme cases, Koi fish die.
The second role played by pond filters is known as biological filtration. This explains why many pool filters are often referred to as bio filters. This type of filtration involves creating a sufficient environment to facilitate the nitrification process. In short, this process involves the transformation of ammonia, which is toxic to fish, to nitrite, and finally to nitrate. To achieve this process, many bio filters use a type of media designed to provide a high surface area. This surface area provides an ideal environment for the growth of beneficial bacteria.
