The amount of cyanuric acid dictates how much of your chlorine is allowed to convert, almost like a drip-feed system. Finally, we have the ideal level of pH 7.4, which places our pool chlorine effectivity at slightly above 50%. High pH Readings Low pH Readings; Poor Sanitizer Efficiency: Poor Sanitizer Efficiency: Cloudy Water: Corroded Metals/Equipment: Scale Formation: Skin and Eye . The more accurate test is the titration. Steadifac is also useful in preventing high readings from oxidized manganese. Chlorine and pH, your disinfection team, are the first defense against germs that can make swimmers sick. Take note that alkalinity levels in pools are not the same as your pH levels. Not sure if its better to have a higher or lower pH when adding chlorine to your pool? Low pH water has a high number of hydrogen ions.

When you add chlorine to your pool, it immediately breaks down into two chemical compounds that make up free chlorine: The ratio of active/weak chlorine you end up with depends on the pH level of the water because, for chlorine to convert into more of the active chlorine, it needs to combine with hydrogen ions. Five ways field service management technology can boost productivity amid labor shortages and beyond. When free chlorine is present in drinking water, this indicates that the water can avoid becoming recontaminated in storage and that a high amount of chlorine has been added to the water to get rid of any viruses and bacteria that are present.

Corrosion can affect metal piping, equipment, and the surface of your pool tiles and concrete. Save time and money by using less chlorine with these helpful tips. Refilling your pool can also throw off your pH, alkalinity, calcium hardness, and other chemical levels. A new CDC report finds that one in five pools in five states in 2013 had to be closed due to serious safety violations, including improper pH or chlorine readings. Iron (Fe) Test Methods: Most total iron test methods require the reduction of iron to its ferrous form. The types of instruments that can be used for measuring free chlorine include amperometric analyzers and colorimetric tests. (2012). In this situation, dosage testing can be helpful to identify how much chlorine should be added to the water before its stored. I read somewhere on this forum that if your chlorine level is high, your pH reading tends to be the same purplish color (appears to be 7.7 to me). Whenever adding any type of pool chemical, always allow the pool water to fully circulate before re-testing the pool water. The minimum temperature of the water in the chlorine contact chamber must be monitored. Remember that hypochlorous acid is HOCl is the killing form of chlorine is made, and sodium ions (Na+) and hydroxide (OH) are made. Treatment for hyperchloremia depends on the cause. Long-term hyperchloremia, however, can cause a range of symptoms. No matter what you use, follow the instructions carefully. pH levels are always high - This is common in pools that use salt water chlorinators as the chlorine generated is high in pH. Cyanuric acid is also called chlorine stabilizer. A problem with cyanuric acid test strips is that they are sensitive to the pH of the water. Prompt treatment can prevent serious side effects, so people who experience symptoms of hyperchloremia should tell their doctor immediately. Water temperature does have some effect on the equilibrium. Since low pH represents a high number of hydrogen ions in the water, and high pH represents a low number of hydrogen ions, you can start to understand the relationship between pH and chlorine. pH levels are always high, but not using a salt water chlorinator - If youve recently replastered your pool (or a new pool) or if your pool has a new pebble finish, youll probably experience unusually high pH levels for the first year or so from the plaster/pebbles. Portable electrochemical sensors and probes can also be subject to interferences. With careful management of fluids and food, and with prompt treatment for any underlying conditions, most people can regain normal electrolyte levels. Add your neutralizer gradually. Also, if test strips are being used, be sure to use strips designed for pool and spa testing. Start your pool with a target TA (Total Alkalinity) of 90 ppm and adjust up or down in 10 ppm increments until pH remains stable depending on whether the pH is drifting up or down and help keep these controls these other pool water conditions.
