Purple SPS Turning White?!?!?

[FxdupCobra]

So I bought this really nice purple Acro. I had placed it in quarantine and observed it for a couple of weeks. In its fifth week I started to notice it was turning white from the center (towards the bottom) of the colony. I started to observe it closer and noticed a small little crab. I didn’t know if it was a good crab or a bad crab but after observing it for another week I realized the acro was turning more and more white. I got the crab off the piece and put the acro in my display tank. Now after 2 weeks 80% of the coral is white and I dont really see any polyps on it. The display has other SPS corals and they are doing fine.

Current supplements I add: Iron & Manganese , Strontium & Molybdenum, Iodine, Alk buffer, Calcium

Any suggestions of what I can do? Add more supplements (Kent coral accel, Kent coral-vite)?

Thank you!

For all the supplements your adding, do you test for them? With reg water changes, these elements are replenished.

If 80% is dead I would frag it to try and save what's left.

Also, posting up parameters will help us get a figure on what's going on.

I do test regularly and replenish the supplements. I will test tonight and post the parameters as well as some pictures.

Thank you ek9vboi for the reply!

Move it to a stable tank as soon as possible until you get things under control.
