Description
SpaGuard pH Increaser - 18 oz
Raise Low pH for Better Balanced Spa and Hot Tub Water
SpaGuard pH Increaser is a quick-dissolving granular water balancer designed to raise low pH in spas and hot tubs. When pH is too low, spa water can become corrosive, uncomfortable, and harder to maintain, which may affect sanitizer performance and contribute to damage on spa plumbing, fixtures, surfaces, and equipment.
This 18 oz bottle is ideal for routine spa water balancing, fresh-fill adjustments, and correcting low pH after testing. By helping bring pH into the recommended 7.2 to 7.6 range, SpaGuard pH Increaser supports better sanitizer performance, improved bather comfort, and protection against corrosion caused by acidic water.
Use SpaGuard pH Increaser when test results show pH below the proper range. Add the recommended amount directly to spa water with the pump running on high speed, circulate for 30 minutes, then retest and adjust as needed.

Dosage Guide
Compatibility and Requirements
SpaGuard pH Increaser is intended for spas and hot tubs where pH is below the recommended range. Always test water first with an accurate test strip or test kit before adding product.
For best results, adjust total alkalinity first, then adjust pH. Once water is balanced, maintain the proper sanitizer level according to your spa care system. Proper pH helps sanitizer work effectively and helps protect spa surfaces and equipment from corrosion caused by acidic water.
This product is not a sanitizer, shock, pH decreaser, alkalinity increaser, calcium hardness increaser, or filter cleaner. Continue regular water testing, sanitizer maintenance, filter cleaning, and drain-and-refill care as part of your complete spa maintenance routine.
