Newbie Overflow question

[Northstar24]

Okay, I'm in the process of coming up with an equipment list and I'm unsure of a return pump

I'm planning on a standard reef ready All Glass 180 with dual overflows. I've seen a few different estimates on-line of what a standard overflow like that flows in GPH anywhere from 400-600 GPH (per overflow)

Using one hole in each overflow as a drain and one as a return, would something like a MagDrive 7 or 9.5 be sufficient as a return pump in the sump?

Thanks!

as long as the return pump outputs more then your input you will be fine.

I get that, I just dont know what the input is for the standard overflows on an All Glass aquarium

The manufacturer rate each overflow at 600gph max so 1200gph on your tank.I recently took down a 210g AGA tank.Realistically,they can only handle 400-500gph each overflow,otherwise they gurgle and burp.A Mag 7/9.5 will work but is somewhat under power.At a head loss of two returns at 5ft,you will barely get 300-500gph out of them.Look for a pump that will do 1200-1500gph at zero head height.Use a ball valve to adjust the flow.Personally,I'm using a Panworld pump(1750gph) externally split into three lines(2 returns,1 refuge) and I still have the ball valve half open.
