I need some assistance in low CH. I was testing about 200 after a 50% drain of my pool. Went to the pool store and asked for CH+ or calcium +. They gave me 4lbs of some stuff, I can't remember the name, in blue bucket. I've looked at pool math and googled calcium chloride but can't seem to find the friendly bbb version?
My readings after using the CH+ from the pool store is now 175 which makes me kinda concerned either with my test methods or of what they gave me.
