 That is my greatest fear!  But after my tank took its turn for the worst, I have decided to change directions for coral.  So I want to make a more desirable reef scape for the new stuff and the fish... 
 
I may do only a few pieces every week with tons of filtration and a water change after each session to help lessen the problems that could arise.  Also nothing new in the tank till everything is done.
