Looking for Hot Tub Chemical AlternativesI have been told there is a way to use vinegar, soda and I don't
know what else in place of chemicals in my hot tub. I can't use
chlorine base products (rash). We can't seem to get the peroxide
products to work right, we have a white grainey residue in tub
now. Had water tested, they said it was "low" on calcium? So I
used calcium plus, got worse. Help!!
