Guest guest Posted January 20, 2008 Report Share Posted January 20, 2008 There is a calculator at www.vita-d-chlor.com to determine the amount of AA needed to neutralize chlorination in water. 4 ppm is the legal limit for water chlorination, but I used 5 and figured it for 50 gallons, which is more than a standard tub will hold with a person in it, and came up with 250 milligrams. Bottom line is, about a quarter teaspoon should more than do it in just about any normal sized bathtub. Daddybob No virus found in this outgoing message. Checked by AVG Free Edition.
