When I got my tank the lady had some dead coral heads in there. The question is, white encrusting stuff seems to be accumlating in both my 150 and my 55 on the dead coral heads AND live rock. Only thing I have done similarly with both tanks lately is water changes using a new ro/di system. I was told that if my phosphates were at 0 that it was one way to tell if it was working properly, and they ARE 0. Just wondering if these whitening spots are normal? Maybe some type of white coraline?
