Anjon Manufacturing - Pond-Filters
Anjon Manufacturing's Frog Filter is a biological waterfall filter designed for mid-size koi ponds. It sits at the top of the pond waterfall, receives water pumped from the bottom drain or pump, and returns filtered water as a waterfall. The design uses biological filtration media bags that are easy to remove and rinse. The low-profile housing integrates naturally into rockwork-style waterfall designs.
