I'm trying to figure out the type and number of powerheads I am going to need for my 90-gallon tank with dimensions 48x13x33 inches. I am planning on it being a reef tank with a few fish. From my research I get the idea that I will need about 20-3 the tank volume for SPS corals when the time comes.
My questions are, can I assume that the movement volumes added together come up with that number? Does the return pump flow volume from the sump play into this number? (For 2700gph, does the 1100 gph at the head at this height mean I only need 1600 more?) How do I determine placement of the pumps?
