Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need isAquarium Co-Op Air Pump with Battery Back Up – Single Outlet, and Airline Tubing and you’ve got a filter that is fully contained within your aquarium. Sponge filters are completely reusable, don’t need any replacement cartridges, and last for several years. Plus, they are gentle enough for betta fish, baby fry, shrimp, and other slow-moving species. Trusted by fish farms and wholesalers, they are an excellent choice for aquarium filtration that you can set and forget.
To optimize the sponge filters performance, weve included an air collar that replaces the need for an air stone and minimizes bubbles coming out of the side of the sponge. The air collar produces smaller bubbles that lessen noise and create more continuous current. If you need greater water circulation, use the included Easy Flow accessory that curves the uplift tube so that water flows out of the sponge filter horizontally across the water surface and around the aquarium.
The Aquarium Co-Op sponge filter is designed using coarse foam so that it can go many weeks between cleanings. The weighted base will immediately sink to the bottom of your aquarium, so no more floating up after a water change or initial installation. Also, the green plastic helps hide algae and blend in with your live aquarium plants.
