Zoas and palys turned brown

[Rctreece]

I bought several frags from wwc and they all arrived a little stressed as I would have expected. Three of them are brown but are opened and the others are opened and have all their colors. My testing is as follows
Ammonia. 0
Nitrite. 0
Nitrate. 2. This had been zero but I stopped nopox to bring it up to 2
Phosphate. 0
Calcium. 425
Alkalinity. 10.9
Magnesium. 1650
Salt. 34.2
Ph 8.08
Please see pics below. They show what they should look like and what they are now. I did acclimatize them and I have a 135 gal with ai hydra 26 Hd

I am new to corals so any suggestions will be very much appreciated.
