I’ve been having an issue recently with my Acans retracting. They’ve been growing on and off for the past year, but I’d never say well. Recently they’ve started not fully extending during the day and their tissue seems to be getting slightly whiter.

Tank is a 12gal
Salinity is 1.026
pH 8.2
Mag. 1450
Calcium 510
Dkh 9
Phosphate .25-.50 ppm
Ammonia 0
Nitrate 20-40ppm

Light is a Kessil A80 at full blue intensity, and that’s puts the par at the Acans around 60. I also have a XR15 Gen6 Blue I could use. I feed them brine shrimp and Coral Vite regularly.

I attached a few photos, the one with coralline visible (and no dragons breath algae) are the current photos.

Any ideas what might be going on? Thank in advance for any help!
