Jeff Posted June 17 Share Posted June 17 My sponge filters stopped producing bubbles. They were working fine. When I take the Ziss air stone out of the sponge, and hold it sideways with the tubing connected, it produces bubbles. But, the second I put it back in the sponge filter, straight up and down - nothing. Sponges have been recently serviced, cleaned out - nothing in any parts of the sponge chambers (snails) Any thoughts? Link to comment Share on other sites More sharing options...
Guppysnail Posted June 17 Share Posted June 17 Dismantle the Ziss stone. Soak the pads in vinegar or replace them. Sometimes just that little extra resistance if a few inches depth and the sponge when the pads are clogged is enough to stop the bubbles. 1 Link to comment Share on other sites More sharing options...
Jeff Posted June 17 Author Share Posted June 17 Pads are brand new. It's a 55g tank. Too high of a tank, apparently. Turns out, the air pump needed to be above the tank, and the sponge needed to be closer to the pump....sigh. Link to comment Share on other sites More sharing options...

mynameisnobody Posted June 17 Share Posted June 17 @Jeff I’ve had the same issue on all the aco pumps on larger tanks. Seems like they are great for a backup if you loose power, but I’ve stopped using them as my main air pump, they just have very little flow, very quickly after cleaning.

Jeff Posted June 18 Author Share Posted June 18 That's what happened to me too. The air supply drastically changed after I cleaned them. Link to comment Share on other sites More sharing options...
