  • Coarse Foam
  • Weighted Base
  • 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.

Only filter I’ll buy from now on

Best sponge filter you can buy. Have one in my shrimp tank and will be buying them for the rest of my tanks.

These foam filters work much better than the fine foam others use. The fine foam clogs too fast.

It works great!

This is my first time using a sponge filter. I am very happy with how well it works in my 10 gallon tank. I will be buying another one for my 75 gallon tank.

Medium sponge filter

I've purchased at least 8 of these sponges in various sizes for different aquariums..I like these best! They seem much more corse than others I've purchased. I don't need to clean as often. I support this company because I believe that they sell quality products, tested and tried by them and I can message them with any questions. I've learned a lot from their videos as well. Thanks aquarium co-op !
