I would tone down your lighting period. The Dawn / Dusk for 12 hrs is fine and dandy. Your full power lights though are too much. 9 hrs is a LONG time. I have a SPS tank and I only run my full lights for 5 hrs.
For softies and LPS, you really don't need to run any longer than 4 hrs. Those ATI fixtures pump out some serious par levels.
