I've had two brand new mag 2's and a (not new) mag 3 that I haven't been able to get to work externally without leaking.
I sent both of the 2's back and ended up getting a 300gph quiet one 1200 instead. I've been using it for about two months on my calcium reactor and am still happy with it.
I'd offer you the mag 3, but a) it leaks, b) it's loud, so it probably needs a new impeller, c) it is currently circulating water for my UV and Phos reactor, but it probably will be getting swapped for another QO1200 soon.
