Pool pH Calculator

This Pool pH Calculator is free and easy to use. Just follow the:

Pool pH Calculator

Instructions to Use the Pool pH Calculator:

Pool Volume (Gal):

  • Enter the volume of your pool in gallons into the “Pool Volume” field. You can use my Free Pool Volume Calculator if you do not already know it.

Existing pH Level:

  • Enter the current pH level of your pool water into the “Existing pH Level” field. pH levels range from 6 to 9 and must be up to 1 decimal place. You can use a pH testing kit or a digital pH meter to measure the pH accurately.

Calculate:

  • After entering the pool volume and existing pH level, click on the “Calculate” button.
  • The calculator will process the information and provide the recommended chemical dosage to adjust the pH level to 7.5, which is the ideal pH level for a swimming pool.

Adjust pH Accordingly:

  • Follow the dosage recommendation provided by the calculator to adjust the pH level of your pool water.
  • Depending on whether your pH level is acidic or basic, you may need to add Soda Ash or Muriatic Acid to achieve the desired pH level.
  • Please note that an adjustment in pH level usually results in a change in other parameters of pool water chemistry, especially alkalinity.

Repeat as Necessary:

  • After adjusting the pH level, you can retest the water and use the calculator again if further adjustments are required.

Monitor Regularly:

  • Regularly monitor the pH level and other parameters of your pool water to maintain balanced water chemistry. Maintaining the proper pH level helps to ensure swimmer comfort, prevent equipment corrosion, and maximize the effectiveness of sanitizers.

Importance of pH Level in Pool


Pool pH is a measure of how acidic or basic the pool water is. The recommended pH range for a pool is typically between 7.2 and 7.8.

This range ensures that your pool is safe for swimming, optimizes the effectiveness of the chlorine, and helps keep your pool clean and clear.

The ideal range would be between 7.4 and 7.6.

High pH levels can cause scaling on pool surfaces and equipment, cloudy water, and reduced effectiveness of chlorine.

On the other hand, low pH levels can corrode pool surfaces and equipment, irritate swimmers' skin and eyes, and decrease the effectiveness of chlorine.

Role of Soda Ash in Increasing pH

Soda ash, also known as sodium carbonate or pH increaser, is used to raise the pH level of pool water. When added to pool water, soda ash works as a pH buffer, meaning it helps stabilize and increase the pH level.

Soda ash works by reacting with the acidic compounds in the water, such as carbon dioxide, to form carbonates. These carbonates act as alkaline buffers, which resist changes in pH when acids or bases are added to the water.

As a result, soda ash effectively raises the pH level of the pool water, bringing it into the optimal range for safe and enjoyable swimming.

The Role of Muriatic Acid in Lowering pH

Muriatic acid, also known as hydrochloric acid, is a powerful chemical used to lower pH levels in swimming pools. It's a clear, highly acidic solution that helps maintain water balance and clarity.

When pH levels in a pool rise above the recommended range, muriatic acid is added to bring them back down. The reduction in pH helps prevent scale buildup, improves chlorine effectiveness, and ensures a comfortable swimming experience.
