4LB. GLB ALKALINITY UP
To Increase Total Alkalinity: 1. 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. Use GLB Test Strips
to test pH and alkalinity. Compatible with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.
