I have a DC12000 on my lifereef. I typically run it darn near full power but prefer DC for the reason that at times I feed heavier or feeding corals and I can turn the pump down a few notches on the controller to ensure it doesnt pull anything out of the water column but it continues to supply O2 to the water. Also when and if I run something like chemipure I can change the flow rates without messing with valves

That all said the default pump sent with the lifereef is a mag18 which is 1800 GPH...
