Spa Choice® Alkalinity Up

Raises Total Alkalinity in Your Spa or Hot Tub

Critical to alkalinity levels in spas and hot tubs, this granular formula effectively raises alkalinity levels which might otherwise cause spa equipment corrosion.  This product is a special compound used to increase the total alkalinity in spa water. 

When the alkalinity level in your spa or hot tub is in range, it acts as a buffer to keep your pH level constant.  The recommended total alkalinity level for spas and hot tubs is 80-140 parts per million (ppm).  If your spa alkalinity level is below 80 ppm, use Spa Choice Alkalinity Up to raise the total alklinity level.  Alkalinity Up:

• Is easy to use and dissolves quickly

• Helps keep spa pH level constant

• Increases the effectiveness of spa disinfectant

• Helps prevent spa equipment corrosion 

• Helps prevent scale formation and etching of spa surfaces

Note: Always adjust your spa or hot tub's alkalinity before adjusting the pH.
