Anyone please wanna take a guess on the GPH for an overflow with demensions ... 4d X 6W X 10 tall?

Just wandering if thats atleast 600 gpm?

It was operated before with a Rio 2500. I'll be using a Mag 7 with it.

I think it's more the bulkhead size that limits the flow.
And possibly the id of the siphon tube.
From the RC overflow calculator:

Using the following input parameters
Gallons per Hour = 600

Drain and Overflow sizes are calculated as
Recommended minimum drain pipe diameter = 1.01 inches
Recommended minimum linear overflow size = 9 inches
