Sponge filter is good for aquarium and provides both mechanical and biological filtration. The air infusion chamber produces numerous minute bubbles which promote gas exchange and increase dissolved oxygen level in tank water.
Just connect the unit with an air pump thru airline tubing and provide both aeration and filtration for your tank.
The sponge traps waste particles mechanically and cleans water without trapping baby fish. They are useful for as breeding filter or as secondary filter. Or they can be used as pre-filtration unit by fitting to an external or a top filter.
