Maintaining the correct chemical balance in a swimming pool is an art, and understanding the nuances of different chemicals is key. Two common chemicals often discussed for pool maintenance are soda ash (sodium carbonate) and baking soda (sodium bicarbonate). While both can influence pH and alkalinity, they serve slightly different primary purposes. NINGBO INNO PHARMCHEM CO.,LTD. is here to clarify these differences and guide you on how to use them effectively for your pool’s health.

Soda Ash: The pH Powerhouse

Soda ash, or sodium carbonate (Na2CO3), is primarily used as a pH increaser. It has a significantly higher pH (around 11-12) compared to baking soda. When added to pool water, soda ash efficiently raises the pH level, making it ideal for pools that have become too acidic. Acidic water (low pH) can damage equipment and irritate swimmers. By using soda ash, you can quickly restore the pH to the safe range of 7.2-7.8, thereby protecting your investment and ensuring swimmer comfort. It also slightly increases alkalinity.

Baking Soda: The Alkalinity Balancer

Baking soda, or sodium bicarbonate (NaHCO3), is primarily an alkalinity increaser. Alkalinity acts as a buffer for pH, preventing rapid swings in acidity or alkalinity. While baking soda does raise pH, its effect is much more gradual and less potent than soda ash. It's the preferred choice when your pool's total alkalinity is low, and you need to stabilize the pH without a drastic increase. Understanding how to raise pool alkalinity with soda ash also involves recognizing when baking soda is the more appropriate choice.

When to Use Which?

The decision between soda ash and baking soda depends on your pool's specific water chemistry readings:

  • Low pH and Low Alkalinity: If both your pH and total alkalinity levels are low, soda ash is often the better choice as it addresses both issues simultaneously.
  • Low Alkalinity, Acceptable pH: If your pH is within the acceptable range but your total alkalinity is low, baking soda is the ideal product.
  • Low pH, Acceptable Alkalinity: If your pH is low but your alkalinity is in the normal range, soda ash is recommended to raise the pH directly.

Benefits of Soda Ash in Pools

Regardless of which you choose for specific adjustments, understanding the general benefits of soda ash in pools is key. It aids in optimizing swimming pool chemical use with soda ash by ensuring chlorine works more effectively and protecting pool surfaces from corrosive acidic water.
