Pool Water Balance
Common Dosing Mistakes

Níveis

Cloro livre: 1-3 ppm. pH: 7,2-7,6. Alcalinidade: 80-120 ppm. No Brasil com clima tropical, o controle é mais exigente — sol intenso degrada cloro rapidamente. Use estabilizante (ácido cianúrico) para proteger.

Manutenção

Teste 2-3×/semana na temporada. Choque semanal. Custo mensal: R$50-100. Adicione cloro à noite (sol não degrada).

⚡ CalcWolf Insight

The most cost-effective pool chemical: liquid chlorine (12.5% sodium hypochlorite). At $4-6 per gallon, it is cheaper per dose than tablets or granular, and it does not add cyanuric acid (CYA) — which builds up from tablets and eventually makes chlorine ineffective. Use liquid chlorine for daily dosing and cal-hypo for shocking.

Frequently asked questions

Frequência de teste?▾

2-3×/semana na temporada. Após chuva ou uso intenso: imediatamente.

Quanto de cloro?▾

Depende do volume. ~200-300g de cloro choque por 10 m³ para subir 1-3 ppm.
