    I'm running a 120 gallon tank, dual overflow. I have 2 Mag 9.5 pumps running my return to the tank. Also have dual adjustable nozzles which gives me 4 directional flows coming back into the tank. I am also running a pair of MaxiJet 1200 powerheads pointed basically at each other. Is this too much?

    LMAO, kinda thought the same thing. Thankfully, no, the sand is not getting stirred up at all.

    I had about 120x turnover when I started my tank up. It seemed worse because I have a much taller tank. No amount of repositioning pumps, rock, etc will make that work out for you.

    I dropped it down some to where there were less sandstorms, but it was really hard on some of my corals. Even if they were getting indirect flow it was too much.

    Dropped it again to about 40x and everything seems to be working out perfect. Although I think the fish really enjoy the stronger currents.
