Ultimate 75 Gallon Setup

[cogreywolf]

I need some help customizing my new 75 gallon Glass aquarium. So far, I am considering having a built-in overflow in the center and having two returns coming out of the overflow. The overflow will head down to my Amiracle wet/dry. How big a pump should I get? Do I need more powerheads in the tank for circulation or will these two returns be enough? If not, should I have the back of the aquarium drilled for two more returns? Please help me design this tank. It will be for FOWLR.

If I am understanding you correctly, I think you are contemplating the same setup I have in my 125. I have a dual return coming out of my center overflow. As long as you have enough water movement from your return pump, you should be ok. I have 1700 gph, but my tank is bigger.
