SčVK reports 68.1 mg/L as CaCO₃ for Dolní Maxov in the Liberecký kraj, a moderate figure at the soft end of that band. The region has several supplies with quite different hardness, so neighbouring villages can differ. Scale will be mild, and detergent dosing can follow the lower end of the pack guidance.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
