About this item

  • Boosts your spa or hot tubs alkalinity level into the optimal range
  • Prevents corrosion damage to plumbing, equipment, and spa surfaces as well as bather irritation
  • All-natural formula stabilizes your pH to make your sanitizer much more effective


Natural Chemistry’s Spa Alkalinity Increaser is used to raise total alkalinity in spa water. Total alkalinity in spa water should be maintained between 80- 120ppm. As a result of the buffering effect of total alkalinity, pH, bather comfort, water balance, and clarity are more easily maintained.
