I believe its 1" drains and 3/4" returns. I wouldn't go over 800 gph for optimal drains. 600gph is a better realistic number with any sort of bends.
Assuming from below the stand, a good pump will be probably the Mag 7 as you'll have to dial back a Mag 9 (from experience). With the slight few feet in head pressure, the 7 will work fine.
I would probably go with the Mag 9. That's what I'm running on my AGA90 with no problems. I know the overflows are a little different, but you should still be pretty good. Besides, that way if you have an extra elbow or two in you plumbing, you don't have to worry.
Overflows are usually installed in the left rear corner on Oceanic and AGA tanks unless specified otherwise. I.e. you can special order an AGA built with the overflow on the opposite side (they just flip the bottom plate of glass).
Thank you for your e-mail and interest in Oceanic products. For a relatively quiet Reef Ready system, we recommend pushing no more than 7-10 times the size of your aquarium per hour. However, the teeth can handle up to 1200 gph.

the teeth can handle that but the 1inch drain can't. Stay between 600-700gph.... Youare gonna add a closed loop right? that is all you need for efficent filtering through your sump...
the real work will be done by the C-Loop!
you should consider adding a durso overflow to your tank, it is quiet. I have and AGA tank. it works great.
The AGA co. and Oceanic employ the same engineer for designed theier tanks. i think they are a division of one another... anyway
I was a little skeptical of the Durso i installed that and my jaw hit the floor. I am gonna do this to all my tankd from now on. it is the slickest thing since snot on a wet windshield
