Key features

• •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.
