When I setup my new 65 gal tank a couple of weeks ago we bought live rock from several lfs. Most of it the coraline algea had turned white. I would assume from not getting any light. We bought a couple of pieces from one lfs that were very purple. Well it is like basically overnight the stuff that was white is starting to turn purple. Does the coraline die when it turns white or does it go dormant? It doesnot appear to be new coraline but the stuff that was there is turning purple. Because I am seeing bits of purple poppin up everywhere.
