SpaChoice 2-Pounds Premium Alkalinity Up – Hot Tub Alkalinity Increaser, 100% Sodium Bicarbonate, Made in USA

Balance spa water with SpaChoice 2-Pounds Premium Alkalinity Up

A stable total alkalinity (TA) is a foundation for comfortable, consistent spa water. This 2-pound bag of premium Alkalinity Up uses 100% sodium bicarbonate to gently raise TA, supporting balanced pH levels and a smoother spa experience. Made in the USA, this granular formula dissolves quickly and works with standard sanitizers and filtration systems to keep your hot tub feeling welcoming after every soak.

Key benefits of maintaining the right TA

• Stabilizes pH to reduce swings that can irritate skin and eyes after a soak.
• Enhances the effectiveness of sanitizers by providing a steady alkaline environment.
• Helps prevent scale buildup on spa surfaces and equipment, keeping the interior looking clean.
• Protects metal components and surfaces from corrosion when TA is in the recommended range.
• Minimizes bubbles or “bounce” and contributes to a smoother water feel during circulation.

What you can expect in real-world use

When water chemistry drifts, a quick adjustment with TA increasers can help you regain balance without interrupting your routine. Injecting a measured amount and circulating gives the product time to dissolve and mix, so test results reflect accurate levels. The 2-pound supply is convenient for regular maintenance without frequent replacements. Expect a straightforward, familiar compound that integrates into standard spa care routines.

How to use SpaChoice Alkalinity Up

• Test total alkalinity with a reliable test kit before making adjustments.
• Add 1 oz (2 tablespoons) of Alkalinity Up to spa water.
• Allow water to circulate for about 30 minutes, then retest.
• Repeat Steps 2–3 until TA is within 80–140 ppm.
• For best results, dissolve granular products first by adding to a small plastic pail filled with water before pouring into the spa.

Tips for maintenance and safety

Keep the spa’s chemistry within practical ranges and follow label instructions. Using Alkalinity Up as part of a regular water-testing routine can help you maintain balanced water for comfortable soaks and longer-lasting equipment.
