I have 2...count them 2 AquaClear 5000's which are basically put into a 901 box anymore if you want to purchase a 901. I recently bought some rio pumps for my wet/dry's and think I'm gonna get a few more to use as powerheads instead of the aquaclear. My reason is because you have to hang the aquaclears where as you have the choice to hang the rio or stick it to the wall. I wanna stick it to the wall baby. Anyone wanna buy some ac5000's?You think the rio's would be more than adequate as a powerhead vs. the aquaclear?
