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.
Aquarium Co-Op Coarse Sponge Filter
I cleaned mine for the first time yesterday after three weeks of use. Didn’t look dirty at all but I was doing a water change so why not. Unbelievable how much was in it! My first time with a sponge filter and I’m loving it.
My shrimp love it.
I love my sponge filter so much I have converted all 7 tanks to them!
