Hi again, Remember I agree and believe in ClO2, below is a good site relating to elements of the human body, now you must admit ClO2 will oxidise some of these properties, and you are correct in what you say with 1ppm dose rates of free ClO2,as good bacteria usually are in a high (pH 7) range and the bad down at the acidic end of the scale, but my argument is that 15 drops of Miracle-Mineral-Supplement activated with citric gives 1000's of ppm of free clo2.
