Bleached Alvepora is it too late?

[starypotter]

Hi everyone,
This alvepora was doing fine just last week. I did a bayer dip (8ml bayer, 2 cups water, 5 minutes on a timer, rinse) and put it in my DT from my frag tank. I did not drip acclimate from frag tank to DT. Both had matched salinity and temperature. Only difference was that frag tank had somewhat high nitrates as it was due for a water change and DT has undetectable nitrates and DT had ReefFlux in it for a bryopsis problem but I had other corals in DT who were just fine, and others survived the move as well. When it was in my frag tank it was just fine. Dip was on Friday, today is Wednesday. Coral hasn't poked out since then. I took a picture of it to ask another question, and it looked like this.

I needed a better picture of something else, so I basted some things in the tank, including the alveopora. A cloud came out like when you baste a really dirty crevice of rock. Then it looked like this.
I just had to pick it up to get a closer look and those holes are empty. It's white and bleached, there might be a small area that's not white and... skeletal but it's tiny. I moved it to the mouth of a cave for lower light and lower flow just in case. Is all hope lost? I feel terrible that I've managed to kill it when it was fine just the other day. It even seemed to be growing since I bought it and now this?

This picture is the last I have of it from one month ago. It got much fuller since then but I don't have any pictures. I've had it just over a month. It was in a low light mid flow area in frag tank, and so I put it only three inches off the substrate in a low flow area of my DT. About 2o inches under black box LEDs set to only about 45%, I do not know the PAR. It was fine before the dip, and I didn't think much of it not opening up right away in DT because it's always been sensitive in QT where if a shrimp touches it it'll retract for a few hours.

I've had corals come back that I thought were long gone. I would leave it and see how it goes

I plan to leave it in there but I don't have my hopes up I could see that all of the holes are completely empty but I certainly won't take it out of the tank.

I also of course want to try to brainstorm what might have happened. All of the other corals that I transferred with the exact same method and time, I dipped them all in the same container, pulled them all out at the same time etc, are all fine and doing happy. One which was looking not so hot before is even starting to look better than it did in the frag tank. I got them all from the same LFS system, were all treated exactly the same but the others are a frogspawn, acan/favia (not sure), galaxea, and another mystery frag.

Can anybody think of why this might have happened?

They are actually a tricky coral.
You also had some issues I belive.

I did, however that was an issue with bayer being introduced to inverts after I intentionally dipped this coral in it. I don't know how in the time span of one week it could have gone from fine to completely bleached and just a hallow skeleton. It wasn't even in the same tank as the one with the problem, it only have a 5 minute dip then into a tank without any issues.

Was the Alveopora placed right next to the Frogspwan coral prior?

No, in the frag tank when it was doing well it had it's own rock, and when I moved it to the DT I placed it about 8 inches below a hammer coral and that was the closest coral. That picture was the day I brought it home and was acclimating everything.
I did put them all in a cup at the same time for the dip with a frowspawn and a galaxea, but they were all retracted the whole time. I do think it was being irritated by the galaxea in the frag tank, but I separated them as soon as I realized and placed them on opposite ends of the tank and it was doing fine after that separation and even grew new polyps.
