Chemical filtration is the simplest way to remove potentially dangerous pollutants from koi ponds. There is a variety of chemical filter media available. Most chemical media remove specific pollutants from the water column while others are combined to create multi-functional chemical filter media that simplify removal of multiple pollutants.
This form of chemical filter media is highly porous and super absorbent. It effectively binds large concentrations of phosphate, dissolved organic compounds, heavy metals, and other pollutants. High phosphate levels reduce water clarity and feed undesirable organisms, such as nuisance algae. If your pond is experiencing high phosphate levels, a partial water change is one of the most simple and effective way to reduce phosphate levels. After a water change, take an active role in keeping phosphate levels low simply by adding more live pond plants or utilizing phosphate removing filter media.
