Product Description

Robarb's Alkalinity Up provides users with the ability to increase their pool alkalinity, along with helping to maintain your pools pH level. Alkalinity Up raises your pools alkalinity, ensuring that pool sanitizers are operating at peak efficiency, stabilizing your pH level, and prevent staining of pool surfaces. Compatible with chlorine, biguanide, ozone, bromine, and salt water sanitizers.

Product Dosage

1 1/2 lb per 10,000 gallons of water will raise alkalinity by 10 ppm.


  1. To keep the pH value of the swimming pool in a stable condition, it is important to maintain the total alkalinity value between the levels of 75 and 125 ppm.
  2. Determine the level of total alkalinity in your pool by use of a suitable test kit.
  3. If the value is below 75 ppm, add a sufficient amount of Alkalinity Up - by pouring it directly into the pool - to increase the total alkalinity to at least 75 ppm. 1-1/2 lb of Alkalinity Up will provide approximately 10 ppm increase in total alkalinity for each 10,000 gallons of water.
  4. Wait at least 8 hours for the material to distribute uniformly before rechecking the alkalinity level.
