Understanding the chlorine breakpoint will enable pool owners to fully grasp the chemistry of maintaining a pool. Pool owners reach the chlorine breakpoint once they have added enough chlorine to the water to meet the disinfection demand. Achieving the chlorine breakpoint is in essence when owners have removed all the unwanted contaminants from the pool water. Remember that pool owners should not simply dump in the chemicals after determining how much chlorine to add to a pool. If applying a higher concentration of chlorine, first dissolve the chlorine in a bucket of pool water. Afterward, distribute the chlorinated water in the pool.
