This is my experience with the ionic foot baths so far. After my question yesterday about the different salts I did 2 foot baths with 2 different salts and tap water and plastic lined tub (water comes from a spring but is disenfected with clorine). Both times the water turned the same color of rose pink and had black particles in the water. Today I bought a new plastic container...did not use plastic bag for liner and used regular Sea Salt . Ater turning on machine I waited about 10 minutes and the water started turning the rose color without my feet being in it. I waited another 5 minutes and placed my feet into the water. After I soaked them for 15 minutes, the water was a little darker rose color. One of the food graters was discolored yesterday when I took it out.(the negative one.)and more so today. I'm thinking that there is black particles in the water due to them coming off the stainless steel graters and the rose pink could be an interaction from the salt or the plastic. I've had 4 ionic foot baths in 2 days and I question if the colors are an indication of detox or we know we are detoxing because we feel better. These are my thoughts of the experience. I'll keep doing the foot baths because they do make me feel better.
