Whether you place your feet in the bucket or not, chances are the water will change colors when the array or water module is turned on. The color changes have to do with:
* The type of water you are using (city water, well water, mineral water etc.)
* The state of your own health.
* Your skin.

When the water becomes excited it ejects tiny particles, and they become visually observable in the water. This will tend to make the water look dirty brown. Of course, just how dirty the water becomes is related to how much sediment is in the actual water.

When you test a bucket of water to see this principle, how dirty it actually becomes will generally be the same each time you use a new bucket of water from the same source. If you were to run this test over and over again but with a different person's feet in the water each time, what happens to the water can be amazingly different. It's the health of the person that plays the vital role in conjunction with the water.

When performing footbath sessions, it is always a good thing to test a bucket of water to see what color it may go as a reference to help understand the color after a treatment.

While the color changes in the water can be dramatic, it is not the most important factor and one must be careful about making any judgments based only on the water color. Some waters do not change color and it is not always an indicator of whether energy is being produced. The best indicator that may be found in the water after a session would be an oily substance located on the container at water level. It generally contains materials released from the outer layers of the skin.

Another indicator after a session can be found in the color change in the urine of the individual treated.

Body function is increased which results in the darker coloring of the urine. A darker coloring of urine can also be seen after eating because the body is processing waste materials, after a session even though no food has been consumed the extra energy seems to activate waste product or toxin removal evident by it presence in the urine.
