   This one is a mith. It depends on the water that you use when you make
it as to the color of the solution. I've had a some that were clear and
still had the same ppm as the ones that were yellow in color. The thing
that I found that makes the yellow color was Distilled ozonated SPRING 
water. The spring water is the key. Why I don't know.
    
   Also another good test if a person wants to gudge the partical size is
to make a batch and have it tested for ppm. That costs $15-20 and most
labs can do it. Then filter the same solution with a .001 micron filter 
and have it tested again to see if there is a difference.
