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.
The item is new and unused, not in the original packaging - reboxed. Full manufacturer’s warranty.
