Air Driven Internal Corner Sponge Filter 5 Stage Biological Aquarium Fish Tank (Upto 120L Tank)

The internal corner filter is excellent for smaller aquariums with size fish like 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.

Please Note: A suitable air pump is required to run this filter (not included). If required, an air pump can be purchased separately from our eBay store.

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.

Multi-layers easy to clean and operate

How Does It Work?

This filter uses bubbles of air from an external air pump, or an integral water pump to draw water through the filter. As water is drawn out through the lift tube or pump, it is replaced by water entering the filter.

The top layer of white filter pad provides a mechanical filtration.  The black bio-sponge in the 2nd layer and ceramic rings with gravel provides biochemical filtration. They support the colonization of bacteria. The bacteria help to break down harmful waste (ammonia and nitrite).

What Maintenance Does It Require?

The sponge will need to be rinsed every time it becomes dirty, about once every 2 to 4 weeks. It’s helpful to reserve the beneficial bacteria by washing the sponge gently with water from the fish tank instead of tap water.
