1 1100 seems like a very low amount of flow in a 90g my tank is 48x24x28 so just a bit bigger than an average 90 and im in the 8000-9000gph range of flow and it seems to be just right for my needs.
if the softies are blowing all over the place what kind of flow is coming from your return? and mabey its just the placement of either the corals or the powerhead
