Aside from my local pool store, do you know where I can find the recommended alternatives such as deicer? We don't have a need for deicer here in Southern Cali. I will need 38 lbs of Calcium Chloride this weekend after a RO treatment. it's $66 for a 50 lb bucket of Hardness Plus from Leslie's which is OK I guess. I shouldn't ever need any more for a few years if I do things right.
