Measuring chlorine levels will help you determine what the current quality of the water is and if additional treatment must be done before consuming the water or using it for industrial processes. Chlorine is more effective at lower pH levels. People should continue testing electrolyte levels as advised by their doctor, since sudden changes may indicate a problem. However, liquid chlorine has a pH of 13 and can cause the waters pH to increase. Chlorine is not as effective. The more acidic the water, the higher the likelihood of corrosion. This increase was independent of whether the baby was premature or had health problems. There are also other test strips available that can test total chlorine and free chlorine levels.
