  • Can Install Air Stone

Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is an air supply 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. Trusted by fish farms and wholesalers, sponge filters are a great choice for reliability and to set and forget.

The Aquarium Co-Op sponge filter is designed using coarse foam so that it can go many weeks between cleanings. The coarse foam with the weighted base means it'll stack on the bottom of your aquarium. No more floating up after a water change or initial installation. Green Plastic helps hide algae and blend in with your live aquarium plants.

Stands up to all the hype

I love this sponge filter, it does more work in shorter time than the supposedly powerful HOB filter I have. Won't go back.

Go coarse or go home.

I have been hobbyist since 1976, and I can’t believe I didn’t come up with this on my own. Simple. No maintenance. User friendly. Incredible bio media. Buy it and try it. It will not let you down. I hate cleaning filters.

Pleased

I did some research on this sponge filter as I have always used a hang on back...I like the fact that I could place it behind plants and it or the tubing can't really be seen. I then bought another one for my husband's larger tank and again am pleased. Truly recommend.
