My recent chem analysis at Pinch-A-Penny stated I need to add calcium chloride to my pool (about 38 pounds!). I have a vinyl above ground pool and have read the debate over whether I needed to add or not.
I had planned to use my old chemical but....I found my Calicum chloride that has solidified into a large block.
Is it still good or useable?
If not, proper way of disposal so I don't surprise my sanitation engineers?
