What kind of lights are you running? It plays a major role in coralline growth, my friend runs basic stock lights and i run HO T5s an my tank is way more colorful then his it leaves him jealous. Also I do get this from time to time, you could try testing other elements in your tank like calcium,magnesium etc i add a lil strontium once in awhile it seems to help

I'm assuming you are talking about coralline algae. While it can be acclimated to high light, taking it from the ocean or dark holding tanks and putting it under 250 watt halides can kill it. It will remain in the shadowed areas though, and eventually grow back. No worries. You don't need to add anything to the tank for it, and adding ANYTHING to your tank without testing for it is not a good practice. You could easily do more harm than good.

It's going to be under that light from now on, correct? I would leave it be. It's not hurting anything to lose some color on the rocks. Like I said, it will come back in time and you don't need it anyway.
