Steadier pH. More Relaxing Soaks.

Build a better foundation for balanced spa water with SpaPure Alkalinity Increaser. This ultra-fast-dissolving formula raises total alkalinity to help keep pH levels more consistent, improve water comfort, and protect your spa and equipment as part of a complete water-care routine.

Even when your pH reading looks right, total alkalinity still matters. Keeping both in balance helps make routine maintenance more manageable, so your next soak can be about unwinding, not chasing changing water readings.

Features & Benefits

• Raises total alkalinity: Helps correct low alkalinity and support balanced spa water.
• Helps stabilize pH: Supports more consistent pH levels rather than allowing frequent fluctuations.
• Improves water comfort: Proper water balance helps create a more comfortable soaking experience.
• Helps protect your spa: Maintaining balanced water helps protect spa surfaces and equipment.
• Ultra-fast dissolving: Makes alkalinity adjustments easy to incorporate into your maintenance routine.
• Compatible with all sanitizers and oxidizing systems: Fits into your existing spa water-care program.

How to Use

1. Test the water: Check total alkalinity and pH before treatment. Alkalinity can be out of balance even when pH is within range.
2. Keep water circulating: Apply to the spa while the water is circulating, following the container label.
3. Measure the correct dose: Use 1/2 ounce (1 tablespoon) per 200 gallons of spa water to increase total alkalinity by 10 ppm, according to the supplied product directions. Follow the current container label for complete measuring and dosing instructions.
4. Retest as directed: Follow the label's circulation and retesting instructions before making further adjustments. If alkalinity needs to be lowered instead, contact your spa dealer for guidance.

Always read and follow the product label for complete dosing, handling, and safety instructions. Never mix chemicals together. Confirm water balance and sanitizer levels meet your spa manufacturer's recommendations before soaking.
