I have a 50g cube 24x24x20 with 2x Vortech MP10 I have them set on Reef Crest Mode at about 80% and they are blowing my sand bed all over the **** place.I tried lowering the output but it just isnt enough, the flow I want and need is at 80% if not more,any suggestions?Im using Natures Ocean Live Aragonite for my SB about 35lbs/2in.
