Hot Tub Chemical Dosing Calculator
Calculate chlorine, pH adjuster, and alkalinity doses for your hot tub volume.
In this article
Níveis
Cloro livre: 3-5 ppm. pH: 7,2-7,8. Alcalinidade: 80-120 ppm. Água quente (38-40°C) exige mais desinfetante. Teste 2-3×/semana.
Manutenção
Troque a água cada 3-4 meses. Limpe filtros cada 1-2 semanas. Choque semanal. Custo mensal: R$30-60.
⚡ 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.
