Normally its caused by intense lighting that the coral is not acclimated to. It can also be caused by the coral not getting enough nutrients .

Oh. How do you increase the nutrients?

Corals need to be fed. There are alot of good corals foods available. Some people target feed there corals i use Redsea reef energy myself. It is a liquid food but it does not take much. You may to make sure you have the correct lighting also.

Now if something got bleached out would the color come back?

If the conditions are improved yes they can come back.

That good to know cause I added a 92w innovative marine tablet light to my tank and seems like my Acans, and lobo have bleached out. Have moved the Acans to a more shaded area.

Cool maybe it will do the trick. You have to have the right spectrum for corals.
