Sick BTA - help and advice

I have a 75 gallon tank setup for over 4 years, but recently overhauled to become a reef tank with the following parameters:
PH: 8.3
NH4: 0
Ca: 440mg/l
KH: 12dkH
NO3: 0
NO2: 0
PO4: undetectable
temp: 76 F
Salinity: 1.026

To get my NO3/PO4 acceptable I went through massive water changes, filtration overhaul and vodka dosing, since this was formerly a FOWLR tank.

To get to my issue I have a BTA that after stabilizing the tank had done really well the first week or so. Since it's had days now of not being fully inflated to completely deflated and disgusting looking. Recently we noticed it seems to deflate and look awful during lighting hours but mostly perk up when the blue spectrum comes on (LED lighting, Orbit Current) where you can see its tentacles looking green and through most of the night.

I have some corals in here that seem to be doing really well, such as hammer, a few variations of torch, trumpet. They are all at a very significant distance from the nem.

I'm at a loss why it's behaving like this other than maybe the water parameter fluctuations it has undergone during some recent large water changes performed and some rock re-arranging? Have I possibly made it sick and should wait it out or find it a new home? The foot from what I have seen has always been well stuck to rock. It does move here and there a few inches.

Any advice is greatly appreciated, and thank you all in advance!
