Hello Tom, or is  it Chuck,

	I would be suspect of the substrate in the tank first (i.e. crushed coral
or lime etc). If this was not the problem then my next guess would be Bio
genic decalcification. Do you have any contortionist or tortifolia Val. in
the tank?
This is about all I can thing of, any other guesses.
