What is a “ good” free chlorine level? Should I swim in a pool with a “low” free chlorine level?

Free chlorine is the most important number to monitor in your swimming pool water. You want it between 1.0-3.0 ppm. Free chlorine keeps the water clean and safe from harmful bacteria.

Question: Should I be swimming in a pool with a free chlorine reading of less than 1.0?

Answer: No! 

Test strips are an easy and convenient tool to make sure your free chlorine is between 1.0-3.0.
