Why does the color and taste of ionic/colloidal silver change from batch to batch?
Distilled water not only varies from one part of the country to another, but bottles of water from the same company can vary. Water, therefore, is the big variable when making ionic/colloidal silver. If you’re uncertain of the PPM you’re producing, it’s best to run the unit until the water turns a pale yellow. You can then cut the time by a few minutes and you should have approximately 5 ppm. You may have to do this test a few times each year to determine how long it’s taking for the water to turn color.
