Hey Matt.
If you are using a glass holes 700 overflow for this tank, you probably don't need to use 1.5" plumbing from the pump. You can't put a ton of flow through those, and they can be a little noisy if you do. A blue line 55 should be plenty big enough to give you 700 gph in the main tank.
Thx Randy, especially with the MP40 I was going to have in the display, flow shouldn't be a problem. I'll have more than enough turn over into the sump with the Blue Line as is... I'll probably end up dialing it down a little... I'm more concerned with the noise from the overflow. If I needed more flow later, it's not a difficult change. (I must have changed the return on my 150 four times.)
