The BioSmart Gravity Filters are a multi-stage mechanical and biological filtration system in a compact package, designed for medium ponds or for ponds with moderate biological load (some fish).
During biological filtration, the water is channeled through a series of filter foams that create a special environment by allowing the settling of beneficial bacteria. During this stage, harmful ammonia and nitrites are converted to nitrates, which support plant life in the pond.
