Yes, it's really, really true. Ordinary chemicals you can get at your supermarket are packaged and marketed as super-de-duper magic (and expensive) miracle fixes!

So...for Chlorine: Bleach or Liquid chlorine.
For raising pH: Borax or Washing Soda.
For increasing Alkalinity: Baking Soda.
For decreasing pH: Muriatic Acid or generic Dry Acid

For stabilizer: CYA powder.

And that's really ALL you need to maintain a sweet, sanitary, safe pool!
