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 was watching Corey on YouTube. And he was doing a pitch on Sponge filters that he sold. So I bought a large one and really liked it. It did a real good job. So then I ordered seven more. I believe they do a good job keeping my tanks clean. I don't have any filters sticking out the top so I can put covers on them. Really like them. Since then I bought a lot of other things which I'm happy with and I will buy more.

Thank you, Larry

Great Filter

I have this hooked up to a Marineland Maxi Jet 1200 powerhead. Works good and fits perfect. My only complaint is it's made in China.
