We have a rena xp2 that we picked up from petland (because I work there) and we have had many fluvals come back, but no rena's. I really like my rena, but we are having the same trouble of cloudy water, even though I don't think it is the pump. I would definatley recommend my filter to anyone who wants something quiet!!! Much less noise than most other filters we have tried!!!
