But assuming you are right about coral war...there was a lot of fresh carbon in there so it would have absorbed what ever chimical from a coral war.
For exemple, my shaggy acropora had a deep dark blue/green base color, now it is all washed out, no more trace of blue in the flesh and the purple tips are bearely visible. That coral is going to have to regain its color back for sure. Now the base color is sort of a grayish flesh but the polyps are still green.
It's not like parts of the corals died either. It's an overall loss of color but the coral is still alive and now making a come back.
I had a multicolor acropora millepora that was striking in colors. It has flashy pink, purple, blue and green hue...now it's livid light green with livid light brown on top. It's like all the nice colors have vanished.
In the morning, most of my SPS has their polyps in and filaments out. I could see something was very wrong.
And what can make xenia melt like that?? It shriveled and died in one night. this is highly unusualy for me as my xenia were growing like weeks and my bleues sponges been thriving for 2 years. What can kill a blue sponge?? I even used a few time Chemiclean in that tank to clear up cyano and that did not affect the sponges. I had an episode of dino and raised the PH a lot to kill that and it did not affect my sponges, nor my xenias.
Now what?
And it's definitly not the temperature, because especially at night my temperature is stable and not affected by the MH light. But even in summer my temperautre is very stable at no more than 77F.

During the night... Maybe corals fighting. Killing parts off. Dead corals lose color too.
Also, too much light is a suggestion. I would still lean to heat spikes.
I had to remove an unfaithful finnex.
Has anyone done extensive research on natures bleaching? Perhaps there are some similar factors we duplicate in tanks. Like pollution.
Can anyone educate us better?
I'm no expert on this issue, just trying to help.
