Leisure Time(R) ALK Alkalinity Increaser, 2 lb

Leisure Time Alkalinity Increaser is a critical product in maintaining proper pH control in your spa. It is comprised of a granular formula that effectively raises alkalinity levels which if left too low, might cause equipment corrosion. In addition to raising total alkalinity, this product prevents pH bounce. Alkalinity Increaser is compatible with chlorine, bromine, ozone, and biguanide sanitizers.


  • Ideal range of total alkalinity in a spa is 80-120 ppm
  • Compatible with all sanitizers including bromine, chlorine and biguanide
