Dying Green Star Polyp?

[Frop]

Sorry for the low quality photo. I noticed this morning that it looks like my GSP has like strings or something fuzzy like on it. Could that be the end? Idk

Last thing that happened was yesterday I noticed my light's aclimation mode was off. So he was probably being hit with 300-350 par. I was trying to run it at 50-75 par since I just upgraded my light..

If anything this intense lighting was just a few hours yesterday (I hope....).

Also I tested all my parameters last night (before I saw this). No alarming numbers.

Looks like a new rock by the green algae on it? IME algae on the purple mat of the polyps will cause them not to open keep them blown off

GSP's are excellent water chemistry indicators
I keep a frag in my tank always to tell me when something is not right.
So with this in mind I would check chemistry also they like high nutrient waters
I have not seen PAR do any noticeable damage to these.
