Kanding in Pingtung County is reported at 93.4 mg/L as CaCO3 by Taiwan Water Corporation (2026 open data). That is moderate hardness. Scale forms slowly, and a softener is rarely the first thing to consider. The file does not name the source water, so we make no claim about it.

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).
