Aquanova Sponge Filter

Aqua Nova Sponge Filter NSF40L.

The Aquanova air operated internal aquarium fish tank sponge filters are designed to provide biochemical filtration in your aquarium. And have an excellent effect on dissolving oxygen in water and work silently.

How they Work:

Attach an airline and an air pump to the nozzle on the sponge filter. As the pump pushes air into the filter, the air will escape up through the filter tube pulling water with it through the sponges thus filtering the water. Simple but effective! The filtered water comes out of the directional outlet at the top of the uplift tube which can be turned to face any direction.

Come complete with suckers for attaching to the tank, and easy to remove sponges which simply slide off, and should be replaced when they no longer bounce back into shape when cleaned.
