I have not changed my mind. If you want to give your feet the ultimate ionic foot bath, soak your feet in home made Colloidal Silver . You can make large batches of ionic silver (2+ Gallons) using the Silver Edge generator. You get pure ionic silver that kills all virus, bacteria, fungus and much more. https://www.youtube.com/watch?v=4FrGCm-9xbM
If you insist on giving your feet an Ionic bath, at least use silver for the anode & cathode then seed your bathwater with some Colloidal Silver (instead of salt) to get the ionic current flowing.
Put ionic silver into a cool mist ultrasonic humidifier located in your bedroom to cure chest colds, pneumonia, bronchitis & more. This humidifier uses 1/2 gallon per night.
