need help w/ a favia brain coral

[Scott 3560]

nees some help, think it dying
I got a real nice one from JNS it was about 6" around, softball sized, and it looked ok at first I think (its my first one) but was slowing dying around the edges,didn't think it was getting light around the edges, so I fragged it up, now it seems like it all dying. The mouths are open and its receeding around most of the edges ???? I need a digtial camera.
everything tests ok cal. a little low but I have slowing been bringing it back up not bad though cal = 340 and ph was 7.8 - 8.0
Its under 250 watt, 20k bulb in a 65 gal. tank its on the bottum with meduim flow on it 1.5" sand bed about 50 LBs. liverock

I also got a candy cane lord & another favia from him at the same time that are doing great and already are spreading to the rocks I glued them to.

what can I do or whats the best conditions for these do they like light or alot of flow, tried moving it around and no real luck ???

thanks Scott

Iodine dip, i would recommend seachem reefdip or kent marine lugols.

might try getting more flow to some of the frags to see if that aids in recovery as well.
