Return Pump Suggestions

[Funky_Fish14]

Anyone think a single SCWD would be ok to use on a Blueline 1100? I know they say then can handle 1400gph, but not sure how this would do. Or For even more variability I was thinking of splitting the return into two lines, then into 4 with the Squids. I will also have the SEIO's running in the tank, these are just for preventing dead spots and some randomization in current. I dont mind 400-550gph out of each output at a time.

Thanks for any input!
