Hot Tub Chemical Dosing Calculator
Calculate chlorine, pH adjuster, and alkalinity doses for your hot tub volume.

Niveaux Idéaux
Chlore libre : 3-5 ppm. pH : 7,2-7,8. Alcalinité : 80-120 ppm. L'eau chaude (38-40°C) nécessite plus de désinfectant car les bactéries se multiplient plus vite. Testez 2-3 fois/semaine.
Entretien
Changez l'eau tous les 3-4 mois. Nettoyez les filtres toutes les 1-2 semaines. Choc hebdomadaire. Budget mensuel : 15-30 €.
⚡ CalcWolf Insight
The #1 hot tub health risk is not chemicals — it is Pseudomonas folliculitis ("hot tub rash") from inadequate sanitization. Maintaining 1-3 ppm chlorine eliminates this risk. The bacteria grows rapidly in warm water (104°F) with low sanitizer — even a few hours at 0 ppm chlorine can cause an outbreak.
