Our Dry Acid buckets include a granular form of acid that helps lower pH, maintain balanced water, and total alkalinity in your pool or spa. This granular form of acid is safer and less caustic than muriatic acid. Being in this form also eliminates spilling or splashing so it’s safer and easier to use. Dry Acid quickly dissolves to start sanitizing on the spot. Use this Dry Acid for a mess-free option to keep your water maintained and balanced properly.
