How It Works
Pond water is pumped into the filter, travels upward through K+Media—trapping debris and cultivating beneficial bacteria— before exiting via top laterals. The filter is easily backwashed by turning the valve and engaging the blower to flush waste.
Gardeners and hobbyists appreciate the high surface area and fast bio-film establishment:
