🧪 1. Step-by-step guide: how to correctly test your hot tub water
To keep your hot tub clean and safe, regular testing is essential. Follow these steps:
1. Use test strips or a digital tester to measure pH and chlorine levels.
2. Check pH: aim for a value between 7.2 and 7.6 .
o Is the pH too low? Add pH+ .
o Is the pH too high? Add pH- .
3. Check chlorine levels: this should be between 1 and 2 ppm .
o Is it too low? Add chlorine granules and let the pump run for at least 15 minutes.
4. Record the measurements so you can track trends.
💡 Tip: Always test on still water (pump off) for an accurate result.

📅 2. How often should you test the water? A handy maintenance schedule
Regularity is key for clear and hygienic water. A schedule will help you stay on track:
• 2 to 3 times a week: Test pH and chlorine with strips.
• Weekly: Add AquaFinesse or AquaPerfect to prevent biofilm and limescale deposits.
• Every 3 months: completely change the water and clean the pipes.
• After intensive use (e.g. a party): add extra chlorine granules and test again the next day.
This way you prevent fluctuations and keep the water quality stable.

⚖️ 3. pH, chlorine and alkalinity : what do these values mean and how do you keep them stable?
The chemical balance of the water determines comfort and safety:
• pH value: influences the effectiveness of chlorine and skin comfort.
o Too low → add pH+ .
o Too high → add pH- .
• Chlorine: kills bacteria and keeps the water clear.
o chlorine granules if necessary .
• Alkalinity : buffers the pH and prevents fluctuations.
o Use special agents (such as AquaPerfect ) to stabilize these.
💡 Tip: Always adjust the alkalinity first , then the pH , and only then the chlorine — that is the order in which the products work best together.

⚠️ 4. Common Mistakes When Testing Hot Tub Water (and How to Avoid Them)
Even experienced users sometimes make mistakes during testing. Keep this in mind:
• ❌ Testing while the pump is running → gives incorrect values.
• ❌ Directly add chlorine granules without checking the pH → the chlorine will then be less effective.
• ❌ Mixing too many different products → can cause reactions.
• ❌ Not taking hard water into account → causes limescale.
✅ Therefore, use AquaFinesse or AquaPerfect regularly to prevent deposits.
Avoiding these mistakes will keep your water clean and clear for longer.

✅ 5. Checklist: How to always keep your spa water clear and safe
A handy routine prevents problems:
• Test pH and chlorine 2-3 times a week
• If necessary, dose pH+ or pH-
• chlorine granules at low levels
• Add AquaFinesse or AquaPerfect weekly
• Clean filters monthly
• Change water every 3 months
This checklist will keep your hot tub ready for use.
