Czym jest
Calcium is dissolved from chalk and limestone as water passes through the ground. Together with magnesium it makes up water hardness, and most of the limescale in a kettle is calcium carbonate.
Skąd się bierze
Groundwater from chalk and limestone areas carries the most calcium; water from granite or peat carries very little. Lincolnshire supplies are typically on the hard side.
Dlaczego ma znaczenie
Calcium is a nutrient and there is no drinking-water limit. Its effects are practical: scale in kettles, boilers and showers, and more soap needed. The result is reported so you can see the balance of minerals and size any softener correctly.
Co można z tym zrobić
Where scale is a problem, a water softener exchanges calcium and magnesium for sodium. A separate unsoftened drinking tap is normally kept in the kitchen. Pozzani supply and install softeners sized to the hardness result.
