Does carbon bleach your corals ? (Kent carbon recall)

What is strange is that the corals are bleaching where the light does not reach, from underneat, so I am not sure if I should increase the light instead because what is exposed to light seem to be regaining a bit of color.

I really don't know what to do now. Seem the coral are missing a lot of zooxanthellae.

I could say I am very lucky. All of them are slowly coming back to life, their color are getting back about half way now. At least I can easily recognize what they were before. Only one, and that is my favorite one, it seems to be struggling to survive. Most part of the coral is covered with brown algae, only 1 small branch is showing a very slight color under T5 lights. I didn't use any carbon right now even I have already switched to a new brand. I got scared from using any brand and I may just follow what some people are doing, no need for carbon in my tank for a while.
My skimmer is also getting back to normal color, it doesn't skim nasty dark color with some black small particles on the skimmer neck like last week. I felt very lucky to get this beast in time to deal with this disater.
As lampshade has said, and me too, no more Kent product for me from now on.
