• Just connect the unit with an air pump thru airline tubing and provide both aeration and filtration for your fish tank.
• These sponge filters do not trap fish fry and are safe for small size fish like dwarf cichlid, guppy, killifish, etc. 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.
