Frequently Asked Questions:
Q.
What is the difference between Free Chlorine and Total Chlorine?
A.
Here's the easiest-to-understand explanation of "total chlorine versus free chlorine".

There's not a lot of non-free chlorine if you are on a city water supply with chlorine used as the disinfectant. You may contact your municipality and ask for an annual water quality report (normally freely accessible by the public), just to make sure.
