Have you ever tested your swimming pool water and couldn’t get a chlorine reading? Figuring you must have done something wrong, you retest your water. Still no reading. So what do you do? Add chlorine, right? After days of adding chlorine and testing chemical levels, you still have no chlorine reading. At this point, your attitude turns from curious to annoyed.
Are your chemical levels imbalanced?
Are you using a reliable pool water test kit?
These are just two questions that need addressing before you can get to the real question, why does my pool have no chlorine?
