BTW -- Agway - carries the Calcium Chloride Flakes (77-80%) $10 for 50lbs (this is 20 cents a pound). I asked them about pool usage -- they indicated a local large water park / pool buys it by the pallet. I added it by mixing small batches in a bucket to disolve the flakes -- worked like a champ just a minute or so to disolve. Now I have some left over to melt ice this winter.


Agway also sells Sodium Bicarbonate (Baking Soda) $8 for 50lbs.
