Sump flow, GPM?

[banditpowdercoat]

Trying just my sump return in the new 150. Originally was going to use a Little Giant 3-MDQX 700GPH pump, pumping 5 ft of head. But, that pump, the bearings were noisy. So the tank came with a LG 4-MDQX 1325GPH pump. Now, I am wondering is that to much flow? the spec sheet says approx 1100GPH with my head. Tank and coast to coast overflow are handling it great. But wondering if maybe I should tap my Berlin Skimmer off it???
