What is water hardness?

Water hardness indicates how many hardness-causing minerals, meaning calcium and magnesium, are present in the water.

We have a very interesting article about this in our support section.

How is water hardness measured?

There are several ways to do this, for example with a titration test. You can find a suitable titration kit in our shop . Instructions/explanations are available in our support section .

We also have a great video on this topic:

What units of measurement are there?

1. German degrees of hardness (°D)
2. French degrees of hardness (°f)
3. English degrees of hardness (°E)
4. Milli-equivalent/l - Millival
5. ppm _CaCO3
6. mmol/l _CaCO3

What should I do if I have hard water?

Water softening reduces the water hardness throughout the entire household. Installing a water softening system lowers the water hardness to a desired level. A residual hardness of 3–6 °dH is typically set.

In our shop you will find the right water softening system for all applications.
