This is the pump we run for our water fall. I liked how efficient it was that I replaced our two pumps that filled our pond with just one of these as well. Our waterfall is about 8 feet high and the top rock is about 5 feet wide.

No mater what pump you choose pick one that is brushless. I am so happy with the above pump. We leave it in the water all winter and its been running flawless since spring of 2013. Just turn on the timer in the spring and away it gos. I have not even picked it up to clean it. I installed it inside a milk crate to act like another screen.

This flow is with one pump and twice when the fill pump turns on.

Cheers Don.

EDIT: P.S. on both pumps I run a full 2" water line.
