where can I get the cheapest calcium chloride?

[bfang711]

I want to bring up the CH level. Can I use calcium chloride from the big box store? A lot of them are for Ice melting. Can I use them? or which brand of product I better use?

thank you.

Yes, you can use them. Some brand names are listed in Pool School - Recommended Pool Chemicals along with instructions for adding each chemical.
