There's an interesting link on Reef Central that Meg started. Apparently he is not the only one with this problem. One of the folks also sent a sample to Randy of RC, with some extremely interesting results!
What I find so darn strange is the apparent randomness of people's problems. Based upon megadolon's posts I purchased the same salt within a day or two of his and have not had any problems...weird!
You don't have to read the entire 5 pages but here is a link to the last one!
Happy reading,
Rob
