    Hydro-Sponge IV Pro filters provide both mechanical and biological filtration. The Pro line is constructed of reticulated foam which doubles its efficiency. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. In addition, the Hydro-Sponge traps larger waste particles mechanically cleaning the water without trapping baby fish. Other sponge filters can't compare to the amount of water the Hydro Sponge can move with the one inch diameter lift tube. The sponge is held on a heavy base to keep the unit stable and the raised sponge design prevents dead space beneath. Ideal for use in hatcheries and breeding facilities. Hydro-Sponge filters can be operated with either and air pump and stone, or a suitable powerhead. The Hydro IV is rated for aquariums up to 80 gallons.

    Sponge Filter 6/13/2013

    Reviewer: KLE

    Originally wanted the larger size, but out of stock. This one is ok. I put an air stone inside and cut the tube to fit. Balances ok on floor and it is still an efficient size for what I am using it for.

    Super easy to set up & use. Very effective! For the money, sponge filters are the way to go!
