The pH levels in the water must come in at around 6.5-7.5 for the free chlorine measurement to be accurate when telling you how much chlorine is present in the water. How Does pH Affect Chlorine Effectiveness? These meters can provide readings that extend from 0-4 mg/L. When chlorine levels are too high, the waters pH will start to decrease, which can eventually lead to corrosion. As weve seen in the chart above, even if you maintain free chlorine levels of 2-4 ppm, if your pH level is too high, then theres still a chance for you to get algae blooms or green pool water simply because the effectivity of your pool chlorine has been lowered by the high pH. You should also look at your pH levels to see if you need to add in pH, as chlorine reduces the amount of pH in water. If a test indicates the alkalinity is very low and the pH is close to ideal, the pH may be wrong. When testing, follow the instructions carefully, including any specified waiting times.
