Rodger, I believe the question is regarding water flow. For example, in my 90 gal tank I have a total of 3 pumps; a return pump rated at 700 gph (after 2' head pressure it's about 600gph), 2 PHs(power heads) with a total gph of about 600 gph. Thus, my water's total turnover rate is 13 times per hour (600 + 600 = 1200/90 = 13 times per hour). I think the minimum should be about 10 times per hour for softies/LPS corals and should be MUCH higher for SPS corals.
