Why Pool Volume Matters

Formeln

Rechteckig: L × B × mittlere Tiefe × 1.000 = Liter. 6×3 m, Tiefe 1,2-1,8 m: 6×3×1,5×1000 = 27.000 Liter. Rund: π × r² × Tiefe × 1000. Volumen kennen ist Pflicht fuer korrekte Chemikalien-Dosierung.

Chemie

Chlor, pH-Senker, Algizid dosieren sich nach Volumen. 30% Fehler bei der Volumenschaetzung = unsicheres oder reizendes Wasser.
