What is Combined Chlorine (Chloramine)? Combined chlorine, also collectively called chloramines, is created by the reaction of free chlorine with contaminates in the pool, often from the ammonia and nitrogen byproducts producing from swimmers and microorganisms.
Chlorine concentrations in the range of 0.1 to 0.4 parts per million are usually maintained in municipal supplies, while ranges from 1 to 3 ppm are used in both pools and spas. Three types of chlorine can be measured: 1  Free chlorine â most effective as a disinfectant. 2  Combined chlorine â formed when free chlorine reacts with other compounds within the water. 3  Total chlorine â the sum of free and combined chlorine.
