I just ordered a blowhole 1450 directly from Reeflo...I won't be using as a return but as a oump to move water around my fish room. I'm a ways out from having it in use but I hear great things on these pumps.

Just took delivery of my BH1450 pump...this thing is compact and very well built. I won't be using it for another 2 months but I love that you can very the strength without having to put in a ball valve on the output with just the dial on the pump. They do have some decent head pressure allowances as well. Take a look at the reeflo site for the specs.
