Live Rock Changing...HELP!!!

[mary787]

My tank is almost 1 month old, and I recently bought 6 pds. of LR, it was nice and had alot of coraline on it, reddish pink, this was last week, today I noticed that alot of the color is gone and is turning kind of brown, what could it be, today I just received my lighting as well, power compacts, 2x65w, 50/50 bulb....is there something I should be watching out for, I also use distilled or purified water only....HELP anyone????:notsure:

it might take a while to come out and grow again, or it could be the lighting factor. the lighting could not be as strong as the tank u got it from

well I do prefer for it be that it was due to the light and not end up being some type of bad algae or something, it's still a shame though
