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.

sponge filters

I have been usin sponge filters for over a year and I love them. Much easier than filters hooked up to the back of tank. Easy to clean and my water is clear and testing kit says A+ I have thrown away all my old filters and very happy.
