Waterfall Filters

Waterfall Filters or, Bio-filters, are generally installed at the top of a waterfall, these are some of the most cost effective and low maintenance systems available. Water from the pond is pumped into the filter via a pump. The water then flows through the filter overflowing from a spillway and eventually returning to the pond via gravity. Waterfall filters can accept substantial flowrates, house a variety of filtration media, and can be buried.
