When water contains a significant amount of calcium and magnesium, it is called hard water. Hard water is known to clog pipes and to complicate soap and detergent dissolving in water.
Water softening is a technique that serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions, iron ions may also be removed during softening.
The best way to soften water is to use a water softener unit and connect it directly to the water supply.
