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.

Easy Filtration, Happy Fish

I got one of these for a smaller tank and it keeps the water well filtered without the harsh water current you might get from some hang-on filters. My fish seem to like the bubbles from it too. The filter is easy to set up and take apart which makes cleaning pretty stress free. When water levels get a little low from evaporation, my hanging filter can start to produce a harsh waterfall noise, this just produces surface bubbles which is nice. Plus, sponge filters save you a great amount of money from having to buy packs of specific filter cartridges all the time. Since I was pleased with my experience, I bought my boyfriends one too. We both recommend you try it out for yourself.

Aquarium co-op sponge filter

I had a sponge filter in my tank already but it never seemed to work. so I ordered the aquarium co-op medium, with the air stone they suggested and it works perfectly. Also the price was about the same.
