About This Item

HTH® Stabilizer helps protect and extend the life of chlorine in your swimming pool. If you’re using an unstabilized chlorinator, adding stabilizer separately can help slow down the effects of direct sunlight on the chlorine levels in your pool. HTH® Stabilizer can be added to the skimmer to help your free available chlorine levels stay between 1 and 4 ppm for healthy swimming. HTH® Stabilizer is great for all pool types including vinyl-lined pools and salt water pools.

  • Helps chlorine last longer
  • Sun protected for longer chlorine life
  • Apply through the skimmer
  • Compatible with all pool types including salt water systems
HTH Stabilizer helps you stay balanced all summer long

Test Water Levels

Next, test and adjust the level of free available chlorine to 1 – 4 parts per million (ppm). Then, measure the cyanuric acid (CYA) concentration. The ideal range is between 20 – 40 ppm.

Add HTH® Stabilizer

If CYA levels are below 20 ppm, then add HTH® Stabilizer directly to the skimmer. Wait for the granules to dissolve before adding any additional pool products. Leave the circulation pump running and do not backwash for at least 48 hours.
