Natural Chemistry Spa pH Increaser - Keeps Spa Water at 7.2–7.6

Overview

Natural Chemistry Spa pH Increaser is a 2.49 lb bottle designed to help spa and hot tub water stay in the optimal pH zone. It uses all natural sodium carbonate to gently raise pH when tests show it falling below target levels.

Why maintain a stable pH

Keeping pH within the ideal range supports comfortable soaks, protects equipment, and simplifies ongoing water care. This formula is designed to raise pH steadily without harsh additives.

Key benefits

• pH booster raises spa water into the 7.2–7.6 range, helping reduce corrosive wear on plumbing and surfaces.
• Stabilizes pH to minimize irritation for bathers while maintaining a balanced spa environment.
• Simple dosing that fits typical spa maintenance routines with clear test-based guidance.
• All-natural sodium carbonate provides a straightforward way to adjust pH as part of regular care.
• Works alongside Natural Chemistry’s family of pool and spa solutions for consistent results.

How to use

• Test the spa water with your preferred test kit and compare results to the bottle chart to determine the required amount.
• With the spa not in use and the circulation pump running, add the recommended amount directly into the water.
• Continue circulating for a minimum of 30 minutes, then retest and adjust if necessary.

What to expect

Regular use as part of your routine can help maintain a comfortable bathing environment and protect spa components from imbalance. Results depend on overall water balance and usage.
