Available Chlorine Content

On page 50 of our Pool & Spa Operator Handbook in chapter 5, there is an excellent chart that lists all the chlorine compounds and their respective characteristics/properties.  One of the properties listed is “Available Chlorine Content.”  You should remember that all chlorine compounds — namely, liquid chlorine, Trichor, Dichlor and such — are NOT created equal! The term “Available Chlorine Content” (ACC) was established to compare the potential […]
