GLB Alkalinity Up
GLB Alkalinity Up increases total alkalinity in swimming pool water. Maintaining proper alkalinity in swimming pool water aids in preventing the pH level from changing.
To Increase Total Alkalinity:
- Determine the total alkalinity level.
- 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.
ALKALINITY UP will provide approximately 10 ppm increase in total alkalinity for each 10,000 gallons of water. Wait at least 8 hours for the material to distribute uniformly before rechecking the alkalinity level.
