The Tetra Bio-Active Advantage Unique open-profile bio-media design gets water to the entire internal surface area. While foam and other closed bio-media designs clog up with dead bio-film, the Tetra Bio-Active Pressure Filter exfoliates old bio-film and leaves a young, thin, highly active bio-film layer for nitrification.
Filter Operation Steps
Water is pumped from the pond.
Water under pressure is forced into the bio-activators which trap dirt and debris.
Beneficial bacteria convert ammonia, which is harmful to fish, into nitrates, which are consumed by aquatic plants. This is known as the Nitrogen Cycle.
