Ok someone please explain to me the difference and use of these products. I dose a two part calcium and alk by seachem. My levels are perfect and I am now looking into Kalk and maintaining these levels. I inherited a kalk reactor recently and have it set up to run off my ATO. I have a gallon of BRS Kalkwasser, a five gallon bucket high purity Magnesium Chloride, and a gallon of Magnesium Sulfate. I have found a lot of info on the two but still am confused on how much and which one to use. What is the difference in the two and is one better than the other?
