No one is going to give you some magic bullet. That being said there is a ton of good information out there. With SPS the key is stable parameters. High light, which you have, massive amounts of water flow, low nutrients such as nitrate and phosphate. Granted everything that is said is relative. People come to the store all the time asking questions, but inn reality if we aren't talking measurable numbers it is relative. To some people 30 Nitrate is low for them while others wouldn't consider low nitrate any amount that a test kit can pick up. The same can be said for the others things.
In my 30 gallon Acro tank I have 2 MP10s ramping to full power with two additional smaller power heads, 2 XR15's ramping to full power, 3 fish (I think too high a bio load), an over sized skimmer. You really need to keep Alkalinity rock steady for a lot of Acropora to be happy. I know folks who run calcium rectors whos alk numbers are high, while most run in the 7.5 - 8.0 range or at least shoot for those numbers.
Do you have more information about your set-up such as nutrient levels, flow, what sps you have tried?
