Biochemical Corner Sponge Filter Air Driven22/04/2021
With two-layer sponge filters, this corner filter combines physical and biochemical filtration for your fish and increases oxygen solubility. The top layer of the white filter pad serves as a mechanical filtration, and the black bio-sponge and ceramic rings work as biochemical filtration and support the colonization of beneficial bacteria.
This filter is excellent for small size fish such as dwarf cichlid, guppy, killifish, shrimp, etc., or for hatcheries, maternity, nano tanks, and fry tanks, as the filter produces minimal current and has almost no way to suck the fish through the filter. Also, the air infusion chamber produces minute bubbles which increase the oxygen solubility.
Simply install an airline into the unit and provide both aeration and physical filtration combining with biochemical filtration for your fish. They are especially useful for breeding small fishes.
