Not to go backwards, but if the only thing you've changed is your lights and the corals were doing fine before that change, that's the one big thing that strikes me as a concern. How did you acclimate to the light change?
Going from PC to MH offers an increase in PAR, but if you switch from PC to MH without any adjustment, it can result in a wide range of problems. Maybe the SPS are using up more CA to grow faster in the higher provision of light, same with alk/etc. Maybe it's a combo?

Maintaining CA & ALK hasn't been too difficult for me. The only times it's difficult is when I'm lazy and haven't taken the time to figure out how much is being used/how much to dose. Now I've settled into a pretty regular routine and I test sporadically. I don't have a calcium or kalk reactor, but dose with Turbo Calcium and Kent Superbuffer.

Nick, you might be on the right track.
I put the Tek Light on the tank and fired 2 of the 4 bulbs on for about three days, then put all bulbs on. Corals dying over time has always been an occurrence for me. Corals just won't do well for some reason.

Have you always had that problem? Corals slowly dying?

I'm guessing its either lighting, or something in the water your not testing for. What kind of water are you using?

Interesting. But your fish thrive?
