Why are they bleaching?

How bad is it?

Has it stopped or is it still happening?

What coral is doing it?

my acans, and its my lighting, its too strong for them. ive moved them into shaded areas, but i was wondering what else I can do to help restore their orig colors.

Bleaching from Light Shock is the result of the coral releasing it's symbiotic algae to try and compensate for too much light. Unfortunately this is a "Knee-Jerk" reaction and is usually more than is needed.

The key now is to lower the light level (which you have done) and maintain OPTIMAL water quality to not add any addition stress to the coral. Give them a few days to calm down and then SLOWLY re-introduce them to light. Remember that your light is too intense for them so you'll want to slowly "Acclimate" them to your lights. Here is how I acclimate coral to light..

Use multiple layers of "window screen" to block some light to approximate how much light the coral was getting before. Then remove one layer of screen a week until all are off. This isn't an exact process and involves a lot of GUESSING but I've not had a single coral bleach trying this method.

good luck and Happy Reefing
