Increases Total Alkalinity in swimming pool water. Maintaining proper alkalinity in swimming pool water aids in preventing the pH level from changing.

Features:

• Aids in preventing pH level from changing
• Easily maintain the proper alkalinity level of 80-120

Compatible With:

• Chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.

Applications:
To Increase Total Alkalinity:

1. Determine the total alkalinity level.
2. 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.
3. 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.

Tips:

• When the pH value of the pool water fluctuates from low to high and back again in a short time, it is usually the result of a low total alkalinity condition of the pool water. Use GLB Test Stripsto test pH and alkalinity.

If the value is below 75 ppm, add a sufficient amount of GLB Alkalinity Up. This will increase the total alkalinity to at least 75 ppm.

1 1/2 pounds of GLB Alkalinity Up will provide approximately 10 ppm increase in total alkalinity for each 10,000 gallons of water.
