Product Description

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

BioSmart filters are packed with many features, including high filtration capacity. Features like a built-in cleaning mechanism and a water temperature gauge make these gravity filters an excellent choice for small to medium size ponds with a moderate fish load. The filter pads have a high surface area, providing exceptional biological and mechanical filtration.
