I bought the more powerful Zoo Med PowerSweep 228 rated at 270 gph
and was quite disappointed with the performance compared to the Maxi Jet
models. The sweeping motion locked up after two weeks of using and needed to be cleaned often. Also there is a ton of lost gph
out the sides and little water gets moved around. I think this ph would be fine for 30 gal
or less but anything larger needs more power.
Last month I bought two Seio Super Pumps
and love the currents I get from them pointed at each other
