I love that quote!

And now that I've read through this thread, I'm considering going with the Mag 3 instead of the Mag 5. Good thing I caught this thread!

Sorry if I'm hijacking here... But would an extra 10 watts in a 30G with a 20G sump really make much difference? It'd be 35W vs. 45W.

You only have two MJ 1200's? Are they mods? you might want to kick up your flow on a 125, I have a 155 with a mag 18 for a return by the time it hit's tank water it's putting out about 650 gph, so with my tunze's combined I have 10,000 gph on a LPS/softy tank. after a couple of weeks with this much flow the corals begin to dig it.

Yes, only two, not modded. They seem to be very happy with the flow currently.
