Sponge filters provide both mechanical and biological filtration. Simply install an airline into the unit and supply both aeration and filtration to your fish. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. As well as, the sponge traps larger waste particles robotically cleaning the water without trapping baby fish. They’re useful for as breeding clear out or as secondary clear out. Or they may be able to be used as pre-filtration unit by fitting to an external or a best clear out.
