Probably browning out due to lack of PAR? Do you have another acropora doing okay in the same area?

What are the parameters of the tank? What light and what percentage is it on? Looks really purplish in the tank to me.

Par is around 250, 6 hours AB+ 6 hour 20k 2 g4 Radion xr15 and 1 ai blade and 1 grow. tank is 30 x 18 inches.
I have a few other acropora doing okay but they are higher up in the tank.

250 par would be a minimum. Bump it up to around 350. The acros in my tank are getting 4-500 and are growing good with no color loss.
