Altering your pH will also alter your Total Alkalinity. Calculating pH requires knowledge of both Total Alkalinity and Borate. This calculator assumes a TA of 100 and a Borate of 0. Calculations are approximate, and for pH changes greater than 0.4, results can be off.
When adding chemicals, it is recommended to add half, wait for one full turnover, re-test/calculate and dose again as necessary.

More About Pool pH
Pool water pH is one of the best measures of balanced water. The pH of a human tear is 7.5, so the ideal range for best swimmer comfort is between 7.4 - 7.6. But 7.2 - 7.8 is also considered an acceptable pool water range. Maintaining proper pH levels is essential for swimmer comfort, protection of pool equipment and effectiveness of the chlorine.
LOW pH EFFECTS < 7.2:
Can cause etching of the pool or spa surface, corrosion of metals, chlorine loss, staining of stairs and walls, wrinkles in vinyl liners, and swimmer skin and eye irritation.
HOW TO RAISE pH IN POOL
To raise pH in pool use washing soda, dosa ash or Borax. Aerating the water will also raise pH in pool water. If the pool has a fountain or water feature, it can be run to raise the pool water pH. Use chemical reagents or test strips to find the current pH
HIGH pH EFFECTS > 7.8:
Can cause Clogged filters, reduced circulation, clogged heater elements, reduced chlorine effectiveness, and swimmer skin and eye irritation
HOW TO LOWER pH IN POOL:
To lower pH in pool use muriatic or dry acid. Both acids work the same, muriatic acid comes in a 1 gallon jugs and is equivalent to 1lb of dry acid. Add either chemical to the pool by pouring in the pool about 6 inches above the surface to avoid splashing. That's how to lower pH in pool.
Tips About Pool pH
Chlorine Effectiveness Based on pH:
|pH||Effective Free Chlorine|
pH drift is common and is due to a number of factors impacting the pool water. Salt water systems are one of the biggest reason for pH drifting up. Liquid chlorine also causes the pH to rise when added to the pool water. These both have a negative effect on the chlorine making the newly added chlorine less effective.
CHLORINE NOT WORKING BECAUSE OF HIGH pH IN THE POOL?:
Don't let a high pH in pool get you down. Oxygen Pools chlorine free pool water treatment eliminates the negative effects pH has on chlorine by not using chlorine. The Oxygen Pools Program uses two components: A Dynamic Oxygen Generator and a weekly dose of the nontoxic, non-chlorine additive.A Chlorine Free Water Treatment For Pools
