I'm actually looking on buying one of these and I have seen the blowers and the Alitas pumps that Kenfish sells in action and is depending on howmany tanks are you using air on and how deep. My choice is the blowers. You can use a main 2" pvc line and hook all your lines there with individual regulating valves. Far more expensive but works like a champ. The Pondmaster that you linked should power around 50 or so tanks according to my conversions.
