Mistic monte bleaching or being picked on?

[Grappler]

Music Monte on back wall of tank has been doing great for years, suddenly this week it starts bleaching out and losing more each day. Has anyone had this issue with there Monte? How can I correct the situation? Can something be picking on it?

What are you current parameters? Have you done anything different? Having SPS myself, I understand that the slightest thing may cause an issue.

I had a mystic sunset that completely bleached due to new lights that were more powerful. I lowered the lights and it started recovering. Then I had a po4 and nitrate spike and it went completely gray. I was sure it was a goner. Nope. It’s still recovering but looking much better. The piece in the middle (which was the original frag) is all that’s left that’s still dead but the monti is working on covering it again
