Dgh water hardness
WebThe General Hardness (GH) is a measurement for how hard or soft water is. Technically, it refers to the amount of calcium and magnesium ions in the water. It’s usually measured in dGH (degrees of general hardness) but can sometimes also be measured in ppm (parts per million). As a rough guideline: soft water is considered to be anything under ...
