Maxima Clams losing color

[sailor moon]

Hi everybody, this time is about my two maxima clams.

Since I have installed the HydraTwentySix HD led light,
Since my water content 520 cal..(now back to 420)
Since the water temperature jumps up to 92 degrees by power outage that cause by Miss Irma.
Since my tank have no power for a day....

Not only all of my corals bleached...look totally white and my clams now..
They are..start losing the beautiful blue and purple..

What should I do...is that normal?
And what can I do to the corals? Was it all because I change the MH to LED?

Thank you guys

Light acclimation can be pretty important – if you don't have a light meter ($12 lux meter at minimum) then you'd stuck guessing whether you really made a significant lighting change or not.

The power outage and temperature spike cannot be overlooked either.

There may be nothing you can do...

But if you happened to be starving the tank, now would be the time to stop. Having SOME nitrates and phosphates in the water will help them all recover to the extent possible. (target 5-10 ppm NO3 and 0.05-0.10 ppm PO4)

Stop any carbon dosing and remove any GFO or other phosphate reducer.
