The BioSmart 5000 Gravity Filter is 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.
BioSmart 5000 features a built-in cleaning mechanism that does not require removal of the filter foams during maintenance.
When used in conjunction with the Oase Bitron C 110 UV clarifier or other specifically marked CWG products, they are guaranteed to have clear water and minimal maintenance. We guarantee that when a tape measure is placed vertically into the pond to a depth of 3 feet, the water will be clear enough to read the 1 inch mark at the tip of the tape measure.
