Item Details

Spa Pure Alkalinity Increaser 2 lbs

Spa Pure Alkalinity Increaser is used to raise the alkalinity level in a spa. Total Alkalinity measures the amount of buffering capacity in the spa's water. Alkalinity acts as a shock absorber for pH. If total Alkalinity is too low, the water becomes acidic and corrodes equipment, plumbing, and more. It can also cause pH bounce.

If total Alkalinity is too high, it can cause scale buildup and cloud the water. If your Alkalinity is not balanced properly, the pH is also difficult to balance.

Spa Pure Alkalinity Increaser Features:
  • Reduces risk of corrosion of metal, pumps motors, and heaters
  • Reduces fluctuating pH levels
  • Dissolves quickly in spa water
  • Active Ingredient: 99% Hydrogen Carbonate
Spa Pure Alkalinity Increaser Dosage:
Add 2.5 tablespoons (1.25 oz) per 500 gallons directly to your spa's water to raise your Alkalinity level 10 ppm.

Note: When comparing Spa Pure dosage amounts to other chemical brands you will find that Spa Pure Alkalinity Increaser offers the BEST VALUE for your money.
