How to Increase Total Alkalinity in a Swimming Pool

- Use a test kit to measure your pool's total alkalinity. It should be between 80 and 120 ppm (parts per million).

2. Calculate the Amount of Alkalinity Increaser Needed:

- Formula: TA(needed) = Desired TA - Current TA

- Example: Desired TA = 100 ppm, Current TA = 80 ppm. Then, TA(needed) = 100 ppm - 80 ppm = 20 ppm.

- Note: 1 pound (lb) of alkalinity increaser typically raises 10,000 gallons of water by 10 ppm. So, for 20 ppm increase in 20,000 gallons, you'll need 2 lb of alkalinity increaser.

3. Follow the Alkalinity Increaser's Instructions:

- Refer to the manufacturer's guidelines for specific steps and dosage instructions.

- Generally, you'll need to:

- Dissolve the recommended amount of alkalinity increaser in a clean bucket of pool water.

- Distribute the dissolved increaser evenly around the perimeter of the pool.

- Let it circulate for several hours before re-testing.

4. Monitor and Adjust as Needed:

- Re-test your pool's total alkalinity after 24 hours.

- If needed, repeat steps 2 and 3 to further increase alkalinity until you reach the desired range.

- Aim for slow, gradual adjustments rather than significant changes at once.

Reminders and Tips:

- Before adjusting alkalinity, ensure your pool's pH level is within the recommended range of 7.2 to 7.8. Balancing the pH first can impact alkalinity levels.

- Total alkalinity is affected by various factors, including bather load, water temperature, and other chemicals. Regular monitoring and adjustments may be necessary.

- Always follow the instructions on the alkalinity increaser product's label for safe handling and usage.
