Reef crystals not dissolving?
I have had a 5g bucket of Instant Ocean Reef Crystals for approximately 7 months though, I am having difficulty getting it to dissolve. I have found the quality of the salt to be fantastic up until now. When I attempt to mix the salt in water I am left with small white particles throughout. Not a great deal, not like all the salt mix is not dissolving, more like just small portions are unable to dissolve. Also the mix lacks the foggy look to it that it usually does. Could the calcium or other minerals be reacting with the salt to affect its solubility? Has this happened to anyone before? Should it be thrown out?
