Description

Master Clear pH Up: Sodium Bicarbonate Spa pH Increaser

Master Clear pH Up is a granular sodium bicarbonate formula designed to raise pH levels in your hot tub water. Low pH (acidic water) can cause skin irritation, corrode spa equipment, and reduce sanitizer effectiveness. This easy-to-use powder can be added directly to your spa water or pre-dissolved to gently bring pH back into the ideal range.

Key Features & Specifications

• Active ingredient: Sodium bicarbonate
• Form: Granular powder — add directly or pre-dissolve
• Purpose: Raises pH levels in spa water
• Ideal pH range: 7.4–7.6 (tolerance range: 7.2–7.8)

Why pH Balance Matters

Maintaining proper pH in your hot tub is essential for bather comfort and equipment longevity. Water below pH 7.2 is acidic and can corrode heater elements, pump seals, and other metal components. It can also cause skin and eye irritation. Water above pH 7.8 reduces chlorine effectiveness and can cause scale buildup. Test your spa water regularly and adjust as needed.

How to Use

Test your spa water pH first. If below 7.2, add Master Clear pH Up in small increments according to the product label. Run the jets for several minutes to circulate, then retest after 15–30 minutes. Adjust gradually to avoid overcorrecting.
