Alkalinity Up - 4 #

Features:

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

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.
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 Strips to test pH and alkalinity.

Compatible With:
Chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.
