Is my SPS dead

[Photobug]

I will get into it later as to why it died, but in the meantime I need to know is it dead. I know it is "mostly dead" but should I just yank it out and throw it away or what to do with it.

Looks completely dead to me. No signs of living tissue or a single polyp extension.

Looks like coraline is starting to cover some of it,

I think that is cyano, Mark.

IMO dead. Sorry my friend.

Thanks as I thought.

It was healthy as was everything in our tank.

First sign was two goniopora die then some bleaching on a monticap. Then this acro started bleaching and candy canes shrunk. All parameters look okay but a maybe 20 PPM Nitrate and Ca is 380.

I have started to treat for Magnesium, what else can I suspect for this die off?
