Cal-Boost from Canadian Tire

Even dow flake was like 77%....and its calcium chloride by weight not impurities. Although there will be impurities of different levels depending on the product that is not what you are looking at when you see a percentage like that when it pertains to calcium chloride. You are looking at the amount of calcium chloride.....so it is how much calcium chloride is in the product but most of the rest will be water and a varying amount of impurities.
