This is another reason that pool water is so dependent on Total Alkalinity. However, there are a couple of drawbacks to using digital colorimeters, which include a high cost compared to other options as well as the need to calibrate the sensor with specific standards. The main advantages of using a pool test kit include affordability and an easy-to-use interface. Keep in mind that free chlorine cant be measured with a pool test kit. Simply drinking enough fluid and avoiding excessive salt consumption can prevent this electrolyte imbalance. After adding MPS, wait at least 12 hours before testing free chlorine. No matter what you use, follow the instructions carefully. Calibrate probes on a regular basis with calibration solutions as recommended by the manufacturer. The varying chemicals may react, and release chlorine gas into the air of your home. So yes, in this case, pH does control chlorine strength (% HOCl). However, such neutralizer solutions are themselves high in pH and the reactions with chlorine are inconsistent in their effects on pH (depending on factors such as the TA level). Potassium monopersulfate (MPS or potassium peroxymonosulfate) is a non-chlorine oxidizer that will interfere in the total chlorine DPD test. Choosing the right type of measurement to use when calculating chlorine concentration depends on numerous factors, which include everything from the cost and accuracy of the method to the total number of samples that need to be tested.
