GLB Alkalinity Up increases total alkalinity in swimming pool water. Maintaining proper alkalinity aids in preventing the pH level from changing. Keeping your pool water balanced is an important step in getting the most out of and preserving the life of pool equipment. This product is easy to apply, just pour it directly into the pool. Alkalinity Up can be used with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.
1 1/2 lb per 10,000 gallons of water to raise alkalinity 10 ppm.
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 ppm to 125 ppm.
Determine the level of total alkalinity in your pool by the use of a suitable test kit. If the value is below 75 ppm, add a sufficient amount of GLB Alkalinity Up by pouring it directly into the pool - to 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. Wait at least 8 hours for the material to distribute uniformly before rechecking the alkalinity level.

Love that you carry GLB... and the delivery was fast. Much Appreciated
Glb Alkalinity Up
We love the reliability of GLB's Alkalinity Up. We have a plaster bottom pool and have always been told by company who put our pool in to put in skimmer closest to filter equipment instead of sprinkling into pool by hand. But do it slowly so you don't clog the line. We always vacuum right before adding as we are also instructed not to vacuum or backwash for at least 2 days after using. A HINT...for more immediate results to increase ppm put in 5 gallon bucket & fill 3/4ths with warm water. Use a mixing paddle rod on your cordless drill to mostly dissolve and still add to skimmer. GLB products in general are really good. That's almost all we use!
