Spa Alkalinity Increaser (2lbs) raises the total alkalinity in your hot tub. This is critical to pH control & effectively raises alkalinity levels which might otherwise cause equipment corrosion. For best results, dissolve granular products first by adding to a small, plastic pail filled with water. Spa Alkalinity Increaser is compatible with chlorine, bromine, ozone and biguanide sanitizers.
Note: We recommend having your water tested professionally either every 2 weeks or once a month to ensure all chemical levels are correct. This will help maintain crystal clear water & extend the life of your spa.
