How do you get the free chlorine level down in your saltwater pool?

To give you an accurate answer, it's important to know how many gallons are in the pool, how high is your Free Available Chlorine (FAC), and what is your Combined Chlorine Reading. Is pool enclosed and protected from sun etc? Is your chlorine generator working properly? You could simply shut down the generator and test your pool everyday at the same time. Keep records of pH, Free Chlorine, Combined Chlorine, Alkalinity, etc. It's important that you maintain a proper pH at ALL TIMES.
