Dry Acid vs. Muriatic Acid: Know the Difference
By Shumaila Saeed || Published on January 13, 2024
Dry Acid, typically sodium bisulfate, is a granular acid used for pH control, while Muriatic Acid, a form of hydrochloric acid, is a liquid acid used for cleaning and pool maintenance.
Key Differences
Dry Acid is a granular form of acid, primarily sodium bisulfate, used to lower pH levels in various applications. Muriatic Acid is a liquid solution, which is essentially diluted hydrochloric acid, commonly used for cleaning and pH adjustment in pools.
