Chlorine in water may be present in two forms, free and combined. Free chlorine does the hard work of killing bacteria and oxidizing contaminants. When you add chlorine to water, you are actually adding free chlorine. When the free chlorine combines with contaminants, it becomes combined chlorine, or chloramines. In water, this form of chlorine has very little sanitizing ability, and no oxidizing ability. Total chlorine is just the sum of both combined chlorine and free chlorine.
Which measurement you use, free or total, depends on your testing needs.

What is free chlorine?

Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool.

Can a free chlorine reading be higher than a total chlorine reading?

Technically no. Your total chlorine reading would include all forms of chlorine, which we tend to lump into to basic categories, Free and combined.
