For chlorine concentration, it is recommended to maintain at least 1 ppm (parts per million) of free chlorine in pools and a minimum of 3 ppm in hot tubs or spas.

However, if you are using chlorine stabilizer or chlorine products with cyanuric acid, it is crucial to ensure that the pH is still within the recommended range. Moreover, the free available chlorine concentration must be at least 2 ppm* in pools.

Avoiding The Use Of Cyanuric Acid In Hot Tubs Or Spas

While chlorine stabilizer or chlorine products with cyanuric acid can be beneficial in outdoor pools, it is advised against using them in hot tubs or spas.

Cyanuric acid is a compound that helps to protect chlorine from degradation by sunlight, but it can interfere with the chlorine’s ability to kill bacteria effectively in a hot tub or spa setting.

The CDC (Centers for Disease Control and Prevention) recommends avoiding the use of cyanuric acid or chlorine products with cyanuric acid in hot tubs or spas. Instead, it is best to stick to chlorine-based sanitization methods without the addition of cyanuric acid for hot tub disinfection.

  • Chlorine stabilizer or chlorine products with cyanuric acid are beneficial for outdoor pools.
  • Using them in hot tubs or spas is not advised.
  • Cyanuric acid can interfere with chlorine’s effectiveness in killing bacteria in a hot tub or spa setting.
