SPS white lines

[OrangeFaucett10]

Hey guys over the last three weeks my encrusting and happy Bill Murray SPS has been suffering from what I can only guess is STN. I’ve had RTN years ago, but this is completely different.

It started with the backside becoming white but leaving the tips still colored, if that makes sense. Over the three weeks it has spread and I’ve had zero swing of anything. I’m crazy consistent, so I’m struggling with this. Also, despite the whiting areas most of the polyps are still extended.

If the polyps are extended it hasn’t lost tissue in that area, thus it can’t be any type of tissue necrosis. Sounds more like bleaching

Yeah I’ve never seen this before. It looks like it’s almost dead on the back

Are there polyps on the white part. I thought you meant there were?

Looks like it's encrusting.
You got a pic of the back?
Or top pic if you shut off all flow and shine some light on it.
