Wanting to build my own system, my pond is small and close to my house, I read alot about the eco 7 pumps, how loud are these? My pond is .165 ac.and appprox. 12 ft deep in the center, would this be overkill? I would rather over build it than under build. This is all new to me, I happened across this site looking up ways to combat duckweed, we got it last year for the 1st time, now coming back. Thanks.
