Some have argued that anhydrous chemicals are cleaner or have better purity due to the fact that it has less water. Is this water in the solution the cause of this impurity? Is one really better than the other? Does the dihydrate powder need more in terms of weight to meet the same concentration. Ie: 1 gram per lite of ca anhy=x ppm ca, and the dihydrate at 1 gram/lt=y ppm ca. Please help solve for x and y and explain difference if any exist? Thanks in advance!!
