I bought a 50 pound pail of Berkley & Jensen (BJ's) Winter Heat Pure Ice Melt hoping that I can use it to raise CH. The label states that it contains pure calcium chloride pellets. The CAS number is 010043-52-4. I looked at the BJ's website but could not find an MSDS sheet for the product. I think it is manufactured for BJ's by Scotwood Industries because I found what appears to be a product with the same name on their website. Their MSDS sheet shows it to contain 90-97% Calcium Chloride, 1-2% sodium chloride, 0-1% strontium chloride and water.
Is this safe to use in my pool to raise the CH?
