Pool pH control: maintaining perfectly balanced water

Pool pH control is essential for keeping pool water clean, safe, and comfortable for swimming. Incorrect pH levels can reduce the effectiveness of disinfectants and cause irritation to skin and eyes.

At Mercapool, you will find everything needed to measure, adjust, and maintain your pool pH within the recommended range.

What is pool water pH?

pH measures the acidity or alkalinity level of water. In swimming pools, maintaining balanced pH is essential for effective disinfection and for preventing damage to equipment and pool surfaces.

The recommended pool pH level is between 7.2 and 7.6.

Problems caused by unbalanced pH

pH too low

When pH falls below 7.2, the water becomes acidic and may cause:

  • Skin and eye irritation.
  • Corrosion of metal components.
  • Damage to liners and pool accessories.
  • Excessive chemical consumption.

pH too high

When pH exceeds 7.6, the following issues may appear:

  • Cloudy water.
  • Reduced chlorine and disinfectant effectiveness.
  • Limescale buildup and scaling.
  • Skin and eye irritation.

Products for regulating pool pH

pH reducers

Pool pH reducers help lower alkalinity levels when pool water pH is too high.
