Hydro-Sponge V filters provide both mechanical and biological filtration. 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. 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 V is rated for aquariums up to 125 gallons.
- Experience crystal clear water, radiantly healthy freshwater or saltwater fish, and whisper-quiet, high flow filtration without constant cartridge replacements or a hazardous impeller
- Quiet and easy to clean - simply rinse and squeeze in used tank water (not tap water!) to maintain nitrogen-fixing bacteria. Inner canister of filter can be filled with activated charcoal, carbon, or other media.
- Hooks up directly to a powerhead or pump, and the diffuser can replace air stones. To set up, simply assemble, bury the base, and connect an air hose.
- Soft foam filters across a wide surface area, creating bubbles to reduce protein buildup and increase oxygen. Ideal for low-current breeding, betta, discus, and turtle tanks.
- Fast-cycle a new tank by transferring a filter sponge from old to new. For even more pristine water and longer filter life, combine with ATI Filter Max pre-filtration or try our Hydro-Sponge Pro line.
