I am currently in the early stages of setting up a 75Gal reef tank. I want this tank to many be LPS SPS. I would like to have some SPS up towards the top of the Live rock. My concern is flow. The return pump in the tank is a Mag 7 and i was thinking of adding two Korila 1050's. Would this give me the flow that i need for my SPS or should i go with the next step up on the Powerheads?
