Magnesium Hardness Checker HC The hardness or hydrometric titer (TH) of water essentially corresponds to the presence of calcium and magnesium salts. It is directly linked to the geological nature of the terrain crossed. A calcareous soil will give hard water while a granite soil will produce rather soft water. The total hardness represents the sum of the calcium and...
