I have a 90G DAS,and im having problems with bubbles! They come from the return pump.i have messed with them to no end and i have only managed to get it to spray bubbles every once in a while.Im also not to thrilled about the sponges in 2 of the overflow compartments,can i replace them with somthing else? Any help will be great thanks...
FYI: the pumps are two maxi-jets 1200
