I was told by several hobbyist that I should have a flow rate of 6000 per hour for my 65 mixed reef. it seems high to me but I purchased a new power head that my moves 3100 gph. I think the koralia evolutions I have are 800 gph. I plugged the new one in, with one koralia, and it's just too much flow. Am I placing the new pump wrong? I had it maybe 6 or 7 inches from the surface.
