I have a 180 with a wet/dry bioball system run by a Quiet One 2200 it also has a HOT Magnum at the other end of the tank.The sponge in the overflow strainer constantly clogs to the point that I have to pull it out and rinse it every few days or the tank itself will almost fill up and run over.My question is should I purchase a new sponge(had it for years) due to maybe the fibers breaking down or what else should I do?
