pump selection/mega flow output

[dsouza]

I have a new oceanic 135 with twin megaflow overflows. My returns have scwds, I was told that 2 MAG18s would be way too much for the megaflows, but the head loss in the scwds I thought was about 40% and I am not sure what the megaflows will do ( I think betewwn 600-800/hour).
I want enough flow throughout my tank. Any advise?
