I'm mostly giving you a bump, but also wanted to say that you won't be sorry w/ the mag. I assume it's for the berlin?
I use this same skimmer/pump on both of my tanks, and it's awesome! A huge improvement from the pump it came with. You can't go wrong, and should you decide to upgrade skimmers, the mag is excellent for other applications. Personally i'm very happy with my berlins.
Good luck witfull, this is a bump to help you out. Got a Mag 7 and sounds like a good purchase. Will keeep you posted on it's performance as a return pump.
Ok, I was going to replace the rio that went bad with another one, pump went bad not the inpeller. I need one for my chiller, I have until the summer to get it going again. So I am now looking at a Mag-drive pump.
