If you are like the majority of us, you probably have put too much chlorine into your pool. Free chlorine levels must be around 0.5 mg/L to ensure that the overall quality of water is maintained throughout the distribution network. Remember TA or Total Alkalinity is the measurement of your pools strong chemical structure which can dictate pH movement that helps convert your chlorine into sanitizing agent once it enters the water in pools. Talking to a doctor about medications that can cause hyperchloremia. Inhibitors are added to minimize this interference but over dosing with these algaecides can cause errors in alkalinity readings. Businesses must take steps to ensure they dont lose valuable information when employees leave for the competition. A healthy pH range is 7.2 to 7.8 (a number that limits chlorine side effects while still adequately killing germs); safe chlorine level in the pool should be at least 1 parts per million (ppm), according to the CDC.
