 Re: My purple on the live rock is being eaten away !!
Coraline grows best in low light. Decrease the time of the bright lights and increase the time on the actinics. You can actually grow coraline with just actinic lighting. Double check your alk also. It should be in the 9-11 dkh range for good coraline growth.

The increase of lighting can shock the contents of your tank. It may take a while and gradual increase in small amounts of light for it to turn purple again.
