Pond Filters Help Keep Water Clean And Fish Safe
In most cases, an outdoor pond, if fed by a natural water source such as a spring or slow running creek, the need for pond filters may be irrelevant. However, in ponds where the water is slow to be exchanged by a natural means, the use of pond filters may be required to keep the water clear and the aroma down to a pleasing level. Especially ponds that house fish will need to have the water filtered to protect the wildlife from harm and to insure that water is inhabitable for all of it residents.
Some ponds that rely on a moving stream to maintain their water level, may be gleaning water from the stream into the pond and pond filters placed in the entry port to the pond can help filter the water before any of the debris makes it into the pond. Leaves and other outdoor particles that flow into the pond should be cleaned out to prevent them from accumulating on the bottom, decreasing the pond's depth over time and to prevent the decaying odor from emanating upwards from the pond.
For ponds that have no natural water source, pond filters are almost a necessity to remove debris as well as the product of any fish in the pond that are going to do what comes naturally. Similar to an indoor aquarium, if the water is left without going through pond filters it will turn murky and begin to smell like the water's inhabitants.
Using Filter Size To Meet Water Demands
The size of the pond and the amount of water it holds will determine the size of pond filters that is needed. Many small pre-formed ponds, available it kit form include a filter with the kit. They are generally designed to work with the size of the pond with which they are included and if the homeowner adds to the size of the pond will need to add to the size of the filter.
In many cases, it is better to have larger pond filters than the water volume requires to insure proper filtration but also to lessen the load on the filter's pumps. If the filter is too small, or is operated without be cleaned when needed, it can damage the pump as well as leave the water dirty. In larger areas two or more pond filters may be required to provide adequately cleaned water to provide a health environment.
