Im using a hammer head pump as a return which is rated at 5800 gph. That in turn is going through two 1.5" seaswirls that will each handle 3,800 gph. Now here is the tricky part. I am going to loose some pressure due to having to pump water about 5' up. What the flow rate coming out of the seawirls is going to be im not sure. Im going to guesstimate around 4000 gph. So the coast to coast over flow is split into two separate chambers. Each chamber will feature a bean animal overflow made of 1.5" pvc. Figured each overflow will handle 1,500 gph. So with two that will be 3000 gph. This gives me 1000 gph in theory that the overflow might not be able to handle. So i can either dial the pump down, or as the bean animal design it would push more water through the secondary pipe hopefully absorbing the entire 4000 gph. We will see what happens once the tank is up. Ill be running it a couple of days with just fresh water to test for leaks and play with flow rate.
Sorry! I forgot you already said that! Can't wait to see how that works for you! makes me want to go bigger too!
