Pool Water Chemical Levels Chart

Home / Pool School / Maintenance / Pool Water Chemical Levels Chart

These are the ideal levels for pool chemistry, or the most acceptable range for proper pool water chemistry. However, while these are the average ideal ranges, certain situations may call for certain levels to be slightly elevated or decreased.

Ideal Pool Water Chemical Levels

  • pH: 7.4 to 7.6
  • Total Alkalinity: 80–120 parts per million (ppm)
  • Calcium Hardness: 200–400 ppm
  • Cyanuric Acid: 30–50 ppm
  • Free Available Chlorine: 2.0–4.0 ppm

pH Chart

Use this pool pH dosage chart to determine how to properly adjust the pH level in your pool. A low pH of 7.1 is desirable when using chlorine and sock, but 7.4 is best for swimmer comfort, surface protection, and overall water balance.

Raising pH with pH Increaser

Total Alkalinity Chart

Use this Total Alkalinity (TA) dosage chart to determine the correct amount of adjustment chemical to use for a desired change in TA levels. Remember — TA buffers pH — so too little TA makes pH erratic, and too much makes pH resistant to change. Use pH Reducer to lower Total Alkalinity, and Alkalinity Increaser to raise the level.

Calcium Hardness Chart

Use this Calcium Hardness chart to determine the correct amount of increaser to add for a desired change in hardness levels. To lower pool water hardness, the solution is dilution! If your water has less than 200 ppm of total hardness, add Calcium Increaser.
