Hello! I just got a new pump, 357 gph Sicce Syncra for my 15 gallon aio. I’m afraid its too much and should have gone a step down, and the flow is just too much for my hammer corals. The pump is set to low, and it doesn’t seem to make any difference where I direct the return. Do I need to consider removing this pump and purchasing a smaller one, which I would like to avoid!

I use 2 x sicce voyager nano's 535 gph in my 15 gallon. One pump of only 357 gph does not sound overpowering.
