Pool Water Balance
Common Dosing Mistakes

Werte

Chlor: 1-3 ppm. pH: 7,2-7,6. Alkalitaet: 80-120 ppm. In Deutschland mit kuerzerer Saison: Abdeckung + Solarheizung verlaengern die Nutzung erheblich.

Pflege

2-3× pro Woche testen. Schockchlorung woechentlich. Chlor abends zugeben (UV zersetzt es).

⚡ 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.
