I got some live rock from my brother to add to my tank....it has been in his sump, in the dark, for months. Today I noticed this white feathery stuff growing all over.....what is it? If it is bad what do I do to get rid of it? The pic only shows a small area coming from the side of the rock, but it was the best I could get. Thanks
