Bio Sponge filter is good for aquarium and provides both mechanical and biological filtration. The aerobic bacteria colonize the sponge and help break down harmful waste such as ammonia and nitrite.
Simply connect the unit with an air pump thru airline tubing and provide both aeration and filtration for your fish.
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.
Good for up to 10 gal tank each. Product dimensions: 3.0"D X 6.5"H
