bryterside Posted December 9, 2020 Share Posted December 9, 2020 We have a 3 gallon cube shrimp tank. At the moment I am running a coop nano sponge filter broke in half. Modifying the sponge filter makes it too small to fit a never clog air stone. I think the tank would do better with more oxygen from the air stone than the minimum filtration a half a nano sponge filter gives. I was curious about other opinions, should I trust my gut and go without a sponge? Link to comment Share on other sites More sharing options...
