I realize that there are many who may know more about the technical part of making CS. I have been using CS for several years, and I use a Hanna unit to measure the CS I am making. When I start wit 0 [zero] PPM and when I remeasure the readings read 5 PPM? What are the PPM being measured if not CS? All I know is the CS I make works, and many people send me their thanks for what it does for them. I do not charge for the CS I give away, many times it is for children, they seem to get well. What can I say! Blessings Ted
