You can see some of their original color in my red house.

Does the loss of color have anything to do with one side of the tank being lit for 5 hours and not the other and then vice versa?

I had problems with frags losing color and bleaching slowly, over a week+ time frame and found that my photo period wasn't long enough (was 4-5 hours, then increased it to 9), and my tank was too nutrient poor (not enough nitrogen).

I fed more, used phoshate remover, increased the photo period and my corals colored back up fairly quickly and began to grow.

The issue of "too much light" can be due to acclimation issues, or not getting enough nutrients. The intense light tells the coral to "do something fast", and if the nutrients aren't there to support the process, bad things happen.
