Powerhead positioning?

[slm32123]

I have my overflow box on the far right of my 75 gallon. One return is in the center, the other is on the far left. I have a powerhead on the far left pointing towards the front and the right, My other powerhead (hooked up through my RKL to be a wavemaker) is just underneath my overflow pointing towards the front and to the left.

Should I move them both to the left side near the top pointing to the right towards the overflow? Or one up top and one closer to the bottom pointing the same way? Leave them where they are? Or something else?

I have a two island aquascape.

Depending on what type of coral you have, I would try putting the power heads on each Side a little less than half way down but towards the back, angled to the front glass. Use your returns to ripple the top of the water.
