well the quoted is with maybe 6" of tubing if that and no head of water. There's actually a graph on my Eheim box that shows how the flowrate drops off as you put more head on the system.generally it's not too bad till you get over about 2 feet then things start to drop off badly. Anyway the original point is, don;t you find that a larger pump doesn't actually make much difference due to diminishing returns?
