SčVK reports 329.3 mg/L as CaCO₃ for Malešov, near Litoměřice, which is very hard. That is well above the Czech values in the soft and moderate categories and typical of hard-water supplies in the Ústí region. The utility publishes one value and no range. Scale will form quickly in kettles, showers and boilers, so a softener is worth a look.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/L.

How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
