The generally accepted formula for breakpoint chlorination is 10x the level of Chloramines in the pool to reach the breakpoint threshold.For example, if your tested level of CC is 0.5 ppm, you would add enough shock to reach 5.0 ppm - and if your CC is 1.2 ppm, you would shock the pool to a level of 12.0 ppm. Calculator You'll need to know your Combined Chlorine reading in parts per million (PPM) before you can use the Shock Calculator. The ultimate objective of the breakpoint chlorination is to reach stage 4, where all the contaminants in the water have been neutralized, the level of chloramines is at its lowest possible and free chlorine increases to the recommended level. Chlorine is constantly being consumed by sunlight and contaminates. 2 0 obj Rate also decreases at temperatures below 30C. Let's watch a video that shows you how to calclate the chlorinator setting. When chlorine is added to water, a reaction is. trichloramine) may also be formed, depending on small excesses of chlorine and pH. 16 oz.
