Thanks for the time you take to do the "science", so that the rest of us can benefit! My husband and I use 3-4 drops of citric acid per 1 drop Miracle-Mineral-Supplement when we activate it, and still get results, so it's good to know that we can go to an even lower concentration. As you say, the more drops of Miracle-Mineral-Supplement you take (ie 12 - 15) the more activator you need, and the fouler the smell/taste. Having less activator will reduce that significantly, and still be effective. Thanks again!
