suggestions for circulation pump placement...

[angeladawng]

I have a 75g tank and have been having nitrate problems so in order to get better flow over my live rock in hopes of helping to bring down my nitrates I ordered 2 more Koralia 1050's (already had 2). Now my tank is a sandstorm. I have been messing with it all day and am not getting anywhere. Is this too much movement? Should I point all the pumps up at the water surface? Maybe take one out and just run 3? It's not like it's going to go bad in the box and maybe just save it for later when I upgrade (can't believe I just said that)

any bright ideas would really help...

I run my 4 Koralia 4's two at time in opposite corners. IMO this keeps the debris in motion so it gets filtered out.

think I got it squared away....put one on each side of the back wall, pointing up diagonally to break surface and put one on each end on the sides pointing down across the live rock. Sand storm stopped and tank is crystal clear again.
