Maintaining adequate free chlorine levels protects swimmers from waterborne illnesses. With free chlorine levels between 1 to 3 parts per million (ppm), you significantly reduce the risk of diseases such as giardiasis, cryptosporidiosis, and other infections. Regular testing ensures that those levels stay within the safe range, promoting a healthier swimming experience.

Water Clarity

Free chlorine also contributes to water clarity. A well-balanced pool with optimal free chlorine levels means fewer contaminants that can cause cloudy water. When you maintain free chlorine between 1 to 3 ppm, it helps break down oils, sunscreen residues, and other organic materials introduced by swimmers. Clear water enhances the aesthetic appeal of your pool, making it more enjoyable for leisure and social gatherings.

Methods to Raise Free Chlorine Level in Pool

Raising free chlorine levels in your pool ensures clean and safe swimming conditions. Here are effective methods to achieve optimal chlorine levels.

Adding Chlorine Tablets

  • Choose Stabilized Tablets: Select 3-inch stabilized chlorine tablets for long-lasting results. These tablets dissolve slowly and maintain chlorine levels over time.
