tomini it is difficult to compare the flow from a sieo directly with a classic powerhead like the maxijet. There is more water moving, hence the gph figures but the output is spread across a much lager area. Feels about the same when you stick your hand in there. There is no question that the larger streams are often much better for reef tanks though.
