As most off you know I got new lights and they are nice BUT since I added them most of the colors on the rocks are turning white. When I had the old lights on, all green was turning to purple or red but since I added the new lights all the green red and pruple is turning white.
It is called bleaching and it is due to such a drastick change in your lighting, basically you are sunburning the symbiotic zooxantheallae within the organism as you would your own skin if you were to go into a strong sun light for many hours without having slowly built up a tan to protect your skin.
And as stated above certain types of coralin algea preffer lower lighting and some preffer stronger lighting. But basically you need to introduce any and all coral, algea slowly to there new lighting conditions if it is stronger than they are used to. That even goes for when you change your old bulbs for new ones you should cut back the hours of light and slowly over then next week increase it back up to it's normal cycle.
