I just had the micro bubble issue. I don't have the cloudy water though. When I found the micro bubbles were coming from my FX6 I researched online and found multiple people with the issues on the FX5 and FX6. I took the filter apart and the pads were not that dirty( light load ). But the chemipure in the filter was really dirty. So I flushed that out thoroughly and while I had the top off I filled the filter housing half way with tap water and put hose redirecting the output tube back into the housing and let it run and flush out the impellter. BIG DIFFERENCE. I could visibly see the flow increase while flushing. When I put the filter back together after cleaning the pads in tank water there were no more bubbles and the flow had increased significantly. I will flush the impeller out every time I clean that filter now. Good Luck.
