Muriatic Acid in Pools

Muriatic Acid is a liquid acid used to lower pH and alkalinity levels in pool water, ensuring balanced water chemistry and preventing scale formation.

Why Use Muriatic Acid?

  • pH Control: Lowers pH levels that are too high, maintaining swimmer comfort and equipment protection.
  • Alkalinity Adjustment: Helps reduce total alkalinity levels to avoid cloudy water or scaling.

How to Use Muriatic Acid

  1. Test the Water: Use a reliable test kit to measure pH and alkalinity levels.
  2. Determine Dosage: Follow the product label or use a pool calculator to find the appropriate amount of muriatic acid.
  3. Safety First: Wear gloves and goggles when handling the acid.
  4. Add to Water: Slowly pour the acid around the perimeter of the pool while the pump is running.
  5. Circulate and Retest: Allow the pool to circulate for 4-6 hours, then retest the water to ensure proper levels.

Tips for Using Muriatic Acid Safely

  • Always add acid to water, not water to acid, to avoid dangerous splashes.
  • Store muriatic acid in a well-ventilated area, away from chlorine or other pool chemicals.

Alternatives to Muriatic Acid

If you prefer a safer, non-fuming option, consider using sodium bisulfate (dry acid) to adjust pH and alkalinity levels.
