FAQ
Frequently Asked Questions
No, hard water is generally safe to drink and may contribute beneficial minerals like calcium and magnesium to your diet.
Signs include difficulty forming lather with soap, white scale deposits in kettles or on showerheads, and spotted dishes after washing.
The opposite is soft water, which is low in dissolved calcium and magnesium ions.
It is commonly treated with a water softener, which uses ion exchange to replace calcium and magnesium ions with sodium or potassium ions.
