Master Clear Alkalinity Up: Sodium Bicarbonate Spa Water Balancer

Maintain stable, balanced water chemistry in your hot tub with Master Clear Alkalinity Up. This 2 lb powder is made from sodium bicarbonate — the most effective and widely recommended method for raising total alkalinity in spa water.

Key Features & Specifications

• Active Ingredient: Sodium bicarbonate
• Size: 2 lb powder
• Purpose: Raises total alkalinity levels in spa water
• Application: Add directly to spa water or pre-dissolve in a bucket of water
• Target Range: 80–100 ppm total alkalinity (acceptable range: 60–180 ppm)

Why Alkalinity Matters

Total alkalinity acts as a buffer for your spa’s pH level. When alkalinity is too low, pH becomes unstable and can swing wildly — a condition known as “pH bounce.” These fluctuations can cause skin and eye irritation, corrode equipment, and reduce sanitizer effectiveness. Maintaining proper alkalinity between 80–100 ppm keeps pH stable and protects both bathers and spa components.

How to Use

Test your spa’s total alkalinity with test strips or a liquid test kit. If levels fall below 80 ppm, add Master Clear Alkalinity Up directly to the water with circulation running, or pre-dissolve in a bucket of warm water before adding. Retest after 15–20 minutes of circulation and adjust as needed. Always adjust alkalinity before attempting to correct pH levels.
