Calcium Hardness Increaser - Calcium Chloride Flakes
Raise calcium hardness in hot tubs and pools fast with food-grade calcium chloride flakes. Soft water below 150 ppm causes corrosion and foaming. Restore the 150-250 ppm safe band in one dose.
- Increases total calcium hardness by approximately 10 ppm per 9 g per 1000 L.
- Protects acrylic shells, jet bearings and heater elements from soft-water corrosion.
- Stops persistent foaming caused by water that is too soft.
- Stabilises pH and prevents wild swings during heating cycles.
- Dissolves quickly in warm water with no cloudy residue when added correctly.
