Spa Pure pH Down


Your spa’s pH needs to be in the range of 7.2 to 7.6; high pH will make the water uncomfortable and can lead to scale formation. A pH in the ideal range is comfortable for bathers and will help prevent equipment from degrading.


  • Helps protect equipment from damage caused by scale
  • Instantly lowers pH in spa and hot tub water
  • Provides comfort to users
  • Made in the USA


  • Apply to the spa while the water is circulating or as it is being filled
  • When pH is above 7.7 add 2 dry teaspoons for every 500 gallons of water
  • Wait 30 minutes and test. If pH remains high, then repeat treatment
