The Pond Boss Filter Kit was designed for smaller ponds that can accommodate about 500 gallons of water. This small pond filter comes with its own pump that sits inside a filter box. The water is then pulled into the filer box by a suction effect that’s triggered by the pump. Once the water is inside, it is filtered through two fine layers of foam pads.

The first layer is bigger and of a coarse constriction, and its main work is to catch debris. The second layer catches dead algae and other smaller particles that may cloud the pond water. For added protection, it has bio balls on the inside that deal with unwanted microorganisms through biol filtration.
