Lower High pH Levels for Comfortable, Efficient Spa Water

Oreq Clear Spa 104° pH Minus is a professional-grade pH reducer formulated specifically for hot tubs and spas. When spa water pH rises above the ideal range, it can cause cloudy water, scale formation, sanitizer inefficiency, and skin or eye irritation. This fast-dissolving granular formula safely lowers elevated pH levels, restoring proper water balance and improving overall spa performance.

Designed for routine spa maintenance, pH Minus helps keep water comfortable, clear, and chemically stable in high-temperature environments.

Why Controlling High pH in Spas Is Essential

Spa water chemistry is more sensitive than pool water due to higher temperatures and frequent bather use. When pH becomes too high (above 7.8), several problems can develop quickly.

Using Oreq Clear Spa pH Minus helps:

• Improve chlorine or bromine sanitizer effectiveness

• Prevent cloudy or dull water

• Reduce scale formation on heaters and surfaces

• Improve bather comfort

• Protect pumps, heaters, and plumbing components

Maintaining proper pH is critical for both water quality and equipment longevity.

Lowers pH Safely Without Overcorrection

Oreq Clear Spa pH Minus is designed to reduce pH levels gradually and predictably when used as directed. The granular format allows for precise dosing, helping prevent sudden swings that can destabilize overall water chemistry.

Controlled pH reduction helps maintain clarity, balance, and consistent sanitizer performance.

Optimized for High-Temperature Spa Water

Formulated specifically for spas operating up to 104°F, this pH reducer remains effective in warm water where chemical reactions occur faster than in swimming pools. It dissolves efficiently and disperses evenly with circulation running.

Ideal applications include:

• Residential hot tubs

• Portable spas

• In-ground spa systems

This product is not intended for swimming pools.

Improves Sanitizer Performance and Water Clarity

High pH reduces the effectiveness of chlorine and bromine, forcing spa owners to use more sanitizer to maintain clean water. By lowering pH into the proper range, pH Minus allows sanitizers to work more efficiently, reducing chemical demand and improving water clarity.

Balanced water also helps prevent scale buildup and surface deposits.

Simple Application for Routine Spa Maintenance

Oreq Clear Spa pH Minus is easy to apply. Add the granules directly to the spa water with circulation running. Always test water before and after application and follow label dosing instructions based on spa volume and current pH level.

Regular testing and small adjustments help maintain stable, well-balanced spa water.
