Boil the water: Boiling water can help reduce ammonia levels in water. How much Calcium Hypochlorite 67% will it take to reach breakpoint for a 120,000 gallon pool, if the FAC is 1.0 and the TAC is 1.5? The importance of break-point chlorination lies in the control of: The killing power of chlorine on the right side of the break point is 25 times higher than that of the left side taste, odor, and increased germicidal efficiency. This process is called breakpoint chlorination. To calculate the breakpoint chlorination for a pool, you can use the formula below or just plug in the data in the Breakpoint Chlorine Calculator: Combined Chlorine Level (CCL) = (Total Chlorine Level Free Chlorine Level). We subtract the TAC-FAC to get the CAC and multiply the CAC by 10. Why is the ratio important?
