I've heard from individuals and read references here about the low cost of salt at Lowe's but when I went to buy it, all they had was coarse-grained salt labeled for water softeners. Is that ok to use? The salt I've used previously was "pool salt" and was very finely ground(@ $8.00/bag!). Other than the 'dissolve rate', is there any difference or are there any special words to watch for on the label? Thanks
