Best salt to add and place to buy?

Thanks very much for the quick reply. I will go with the solar salt crystals. BTW my friend just purchased salt for his pool from the local pool supply and it was double $12 bag vs $6 at Lowes. That is a huge markup.

I will also check the grocery store and thanks again this was very helpful.

It's been a few years, but the company I worked for in Va., used to just pick up coarse granular (no additives) salt from the local 'seed and feed' - they sell it for giving to farm animals. I don't know how competitive their prices were, as they were the only place we bought it.
