I have a huge plating red Monti colony, about four years old or so. In the past week or so it has begun bleaching, turning more and more light pink. I hadn't checked my levels in a while, so I tested and found that I had no nitrates, low alk, low ph. I've dosed over the past few days, and added flourish to raise nitrates to 10. Everything is at proper levels now, but the Monti is still bleaching, worse every day. I have a bunch of big frags separate from the colony which are also lightening. Nothing else in the tank is having any problems. I have colonies of birdsnests, duncans, trumpets, a huge stunner challace, green branching Monti, several other plating stuff that looks monti-ish, and lots of other misc corals, plus some polyps and other soft stuff. All in perfect health. What could this be? I'm afraid I'm going to lose the whole thing if I don't figure this out fast! It's an emergency! Any ideas much appreciated.
Stats, JIK you need em:

Ammonia 0
Nitrites 0
Nitrates 10 (was 0)
Phosphates .018
Mg 1400 (was 1200)
Calcium 480 (was 400)
Alk 6 (was 3) (still dosing up)
Ph 8 (was 7.4)
