Where To Buy Chemicals

You could use road salt for this?! I think I will stick to bleach. LOL

Actually if you go to the Dow Chemical website they have a page on pool/spa use for DowFlake calcium chloride, which is usually sold in hardware stores as a road de icer!

Also, here is a calculator to convert from the flake form of calcium choride (DowFlake or the type sold in pool stores) to the pelletized form which is more concentrated and seems to be more redily available

They are one of the largest manufacturers of calcium chloride and I will bet that most of the pool calcium increasers are just repackaged DowFlake. DowFlake is MUCH cheaper than a pool calcium increaser!

Lowes also carries calcium increaser much cheaper than the pool stores.
