A SIMPLE ADJUSTMENT OF ALKALINITY
Pool and spa operators and owners should test for
alkalinity regularly. The amount of alkalinity increaser needed to raise
alkalinity is easily calculated utilizing the chart that follows.
When total alkalinity testing is not available, it is still possible to safely increase the value to a more optimum level by using a pH test as a guide. If the pH is less than 7.2, the total alkalinity of the pool water will likely always be below 70 ppm. In this case the addition of at least 60 ppm of alkalinity would be required. Adding 9 pounds of Alkalinity FirstTM for each 10,000 gallons of pool water will raise the total alkalinity by 60 ppm, and this will usually raise the pH of the pool water into the desirable range of 7.2 to 7.8.
