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.

TA ~85 ppm (55 g / 1000 L) |
TA ~70 ppm (100 g / 1000 L) |
TA ~40 ppm (150 g / 1000 L) |
TA ~25 ppm (200 g / 1000 L) |
|---|---|---|---|---|---|
| 750 L | ~19 g (¾ cap) | ~41 g (1½ caps) | ~75 g (3 caps) | ~113 g (4½ caps) | ~150 g (6 caps) |

| 1250 L | ~31 g (1¼ caps) | ~69 g (2¾ caps) | 125 g (5 caps) | 188 g (7½ caps) | 250 g (10 caps) |
| 1500 L | 38 g (1½ caps) | 83 g (3¼ caps) | 150 g (6 caps) | 225 g (9 caps) | 300 g (12 caps) |
| 1750 L | 44 g (1¾ caps) | 96 g (3¾ caps) | 175 g (7 caps) | 263 g (10½ caps) | 350 g (14 caps) |
| 2000 L | 50 g (2 caps) | 110 g (4½ caps) | 200 g (8 caps) | 300 g (12 caps) | 400 g (16 caps) |
Tip: Add in stages. Test between additions to avoid overshooting the target range (80–120 ppm).
Application Steps
- Test the water: Use LaMotte 3-Way Test Strips to measure alkalinity.
- Measure: Refer to the chart above for dosage based on your reading.
- Add: Sprinkle Jacuzzi® Alka-Up evenly across the water surface with the circulation running.
- 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.
