yeah the ones at the store suck though, not sure why, but some of the corals look great, others aren't I think i need to go in and run some test on the water, maybe order a test for magnesium...I don't know. SPS are still pretty new to me.
You might want to talk to Matt, he picked up some really nice brand new electronic ballast online somewhere, he put them on the three DE 250s on the big tank, and WOW! huge increase in lighting, but he pretty much went from really crappy ballast, to really good ballast.
With yours, it would probablly be a noticable increase, but not as much.
