Water first flows by a UV, and is pushed through specially-developed bio balls inside a biological filter for ammonia and nitrite reduction.
Bio filtration is a chamber containing living bacteria to capture and biologically degrade nitrogens in ponds. Bio filtration is required to break down ammonia into nitrite and nitrite into nitrate.
