Another thing to consider is the photoperiod. Even with great lights, if you're blasting them for too long or too short, they won't thrive. I run mine for about 10 hours, with a ramp-up/down period.

Good point. I've been running my lights for 12 hours straight, and some of my corals look stressed. Gonna cut it back to 10 and see if that helps.
