Acro help- paling/bleaching

[woodhouse]

Ok, so I’m getting some conflicting information on my research on what to do with this acro. It’s a WWC fruit mix and it’s getting really pale but I’m not seeing any rtn or stn as of now. The lighting where it’s placed is only around 200par at the moment and it’s been lower as the lights have been on acclimation mode since the acro has been in the tank. I also started it in the sand bed for a few days prior to moving it up the rock work.
My parameters have been fine, nutrients maybe slightly low but not bottomed out. And alk was raising slowly as i wanted to try out a higher dkh.
Parameters:
Alk - 8.6, was at 10 and I slowly lowered it back down over the last several days.
Phosphate- .02
Nitrate 2.7
Calcium - 435
Magnesium - 1560
Salinity - 35
Temp - 78* F
PH - 8.2-8.4

I’m not sure exactly what’s causing the paling as all my other acros are doing fine. Should i lower it to a lower par for a while to see if it colors back up or will that make it worse?
I havnt seen this acro have any polyp extension since it’s been in the tank, roughly 2-3 weeks. Yet, i just added the other acros to the tank and they all opened up within an hour.
Any guidance would be greatly appreciated!

Don’t think it’s dead. I can still see the green polyps and the pink flesh. Hard to see with the photo.

Yeah that's a goner. The Zooxanthella have been expelled, hence the very light color/bleaching. Many people who have kept acros have been through the same thing (including myself - multiple times). Could be any number of things that caused it. Your tank looks very new without any kind of algae on what looks like dry rock. New tanks are very susceptible to parameter swings and it's tough often to keep it stable enough not to tick off a new coral.

I would chalk it up as a loss and get something else to put there.
