What causes the bath water to change color?
You will notice changes in the color and the deposits left in the water after your ionic Spa Foot Bath session. ionic Spa Foot Bath uses water as a medium through which it delivers its message. Even seemingly clear water is full of dissolved minerals and other chemicals. When the electrical current passes through the water, these dissolved particles begin binding together until they become visible and result in reddish, brown, or greenish coloration to the water.
