Powersweep pumps?

[mikelar]

I have had very good success with the power sweep. I noticed a definite improvement in my corals health once I installed one. I would advise buying the model with the foam prefilter as it helps the pump run longer without having to take it apart and clean it. Even with the prefilter install I find that I have to clean the pump every 2-3 weeks to keep it rotating smoothly
