Color change and High Temperature connection?

[vinsaltank]

Hi guys.
Any another of you notice a color change after high tank temps?
Ill post some examples of what happened in my tank.
Same corals.. Before and after.
Same lighting also.

yes, my coral tree which got hit hard, turned a tan color to a more purple color . my other corals have not changed color. I am glad to see this thread, bc I just thought it was me!

Looks like bleaching to me. Hopefully they can recover. Do you spot feed?

No spot feeding yet... I do add a mix of phyto and zooplank about every other day and shut my skimmer off for a few hours during this "feeding " period.
Ok, I have plenty of utencils to spot feed with.
What should I make the spot food out of? How thick should it be?
How much, How often?
Will this nuch food make my already nuisance algea overtake the tank?
Sorry for the questions?
another before and after shot set I found.

At one point last month, my old glass Thermometer read 94 degrees.
I think it was at least 90 degrees.
I lost like 15 pieces. ( I posted a thread when that happened, if you would like to see what died.)
My new digital thermometer said as high as 88 degrees.

It has been under 83 for 2 weeks or so.

Do more water changes and spot feed with chopped frozon food about every other day. Just a little is all. Enough fro them to grab some. Could take weeks/months for algea to rebuild in side of corals. Hopefully it will. Untill then you must/should feed them.
Why did temp get so high? Did you solve that problem.

My Central air conditioning unit popped.
It will be fixed when I can get the $4500 for a new condenser unit.
( Probably a few weeks)
So after reading all the advice here--
The dehumidifier and surface water fans.. I have consistantly kept the temp below 83.
I found some new sponge growth when removed some dead corals.. ( as seen in picture 3)

Are the other pictures new additions, or did they make it through the high temps?
What are your water conditions other wise, and what type of light are you using?
