Those perameters all look good except the calcium could be better. 300 isn't too low, but I'd try to get it up as much as you can.. what are you using for calcium supplement? Also, it wouldn't be a bad idea to bring the gravity up a little higher to 1.025/26..

There are so many cuases for bleaching it can be hard to narrow it down.. Any temperature spikes recently or way prolonged photoperiods?

There's an awesome article on bleaching in the new marine fish and reef 2002 annual.. I suggest you pick it up.

I'll let jamie, darren, marc, etc. take it from here..
