Hi Karch;
Bleach IS a regular pool chemical -- it's sold in pool stores as "liquid chlorine". Likewise, baking soda (~$0.50/lb ) is sold in pool stores as Alkalinity Increaser at $2/lb. And borax -- 20 Mule Team borax, ~$0.75/lb at Walmart -- is sold in pool stores as "Proteam Supreme" or "BioGuard Optimizer" at up to $5/lb.
But, to go a bit further, read the BBB page link in my signature.
Good luck!
