I've done a 20% water change this morning in my rsm130 and ever since there are loads of micro bubbles! I'm running an AFM skimmer and it has a jeboa pump.... The skimmer I'm still trying to get it to run right (it is more submerged than usual so I can close lid, and still overflows the cup often!!) but it's always seemed to be skimming. The pump has been fine. Has anyone else had bubble issues after a WC!??
