Jacuzzi® Alka-Up

Jacuzzi® Alka-Up is a granular product formulated to raise the total alkalinity (TA) of hot tub water. Proper alkalinity levels keep pH stable, protect spa equipment, and ensure a comfortable, irritation-free soak.


Why Total Alkalinity Matters

Maintaining your spa’s total alkalinity in the ideal range (80–120 ppm) is essential for:

  • pH Stability: TA acts as a buffer, preventing rapid pH swings that cause scaling or corrosion.
  • Sanitizer Efficiency: Balanced alkalinity helps chlorine or bromine work effectively to keep water clean.
  • User Comfort: Stable water chemistry minimizes skin and eye irritation for a more enjoyable spa experience.

Dosage & Application

One capful from the 750 g container ≈ 25 g.
Always circulate water for 30 minutes and re-test before adding more.

Tip: Add in stages. Test between additions to avoid overshooting the target range (80–120 ppm).


Application Steps

  1. Test the water: Use LaMotte 3-Way Test Strips to measure alkalinity.
  2. Measure: Refer to the chart above for dosage based on your reading.
  3. Add: Sprinkle Jacuzzi® Alka-Up evenly across the water surface with the circulation running.
  4. Re-test: After 30 to 60 minutes, re-check alkalinity and repeat if needed.

Safety Precautions

  • Wear gloves and eye protection when handling chemicals.
  • Use in a well-ventilated area.
  • Store in a cool, dry location, away from children and direct sunlight.

By including Jacuzzi® Alka-Up in your regular hot tub care routine, you’ll keep your water stable, your equipment protected, and your soaking experience comfortable and safe.
