So I'm still in the process of building my reef tank. Its a 125 gallon. I just got the courage up and drilled my two 2 1/4" holes for the Modular Marine low profile overflow box. It's rated at 1600 gph. The return pump is an eFlux LOOP DC 1900 GPH that I can dial in. I'm about to drill the 1 1/2" hole for my 3/4" return line but I want to make sure thats enough. I see where many of you have two returns drilled.
I have two 2100 GPH eFlux wave pumps so I'm not too worried about water movement I think. Would the one return line do it? Is there a reason I should have two? I know now's the time to do it.
