Testing: Sample some of the nano-water by holding a small amount in your mouth to verify the bitter taste at the back of your throat. This indicates a concentration of at least 20 ppm. I prefer to use 50 ppm for all applications, such spraying in eyes for Pink Eye. Do not dilute CS water, if possible in order to preserve the Zeta Potential. Electrical conductivity measurements in microSiemens measure positive metal ions and under represent the negative nanoparticles. If you cannot taste the metal, then it is not strong enough. Continue for another 24 hours.
