Dying Brain- Please help!!

This coral has been in this spot for over 6 months, and did very well. Now it seems to be dying. Any advice?

 

How old are your lights? How bout water params? Has your temp been steady?

 

Temps steady at 78 degrees. Lights are only a little over a year old.parameters i'm not really sure about, but all other corals seem to be doing fine. I'm not at home, so i can't check the parameters. I'm going to have my wife go to the LFS, and have them run some tests. I won't be back home till friday.

 

Your overdue for new lights........On the left part of the pic, that is recession right? Put him in a low flow area and spot feed him everyday. If you can, get yourself some TMPCC, Restor or Revive and give him a little dip.

 

I may be a little late jumping in on this thread but did you notice a brown, jelly like substance anywhere on the coral? Is the coral still alive?
