pH CORRECTION
When the pH and the alkalinity of water are low, the water is likely to be acidic in which case the pH should be corrected. Acidic water causes pin-holing of copper pipe and hot water cylinders. This frequently leads to copper leaching into the water causing discolouration (blue tinge / staining) of sanitary ware and blonde coloured hair.
The simplest and most convenient way to raise pH is to run the water through a vessel containing a bed of specially activated limestone. This usually takes the form of a mixture of calcium and magnesium salts. The media gradually dissolves, increasing the pH of the water. This type of unit is called a pH corrector.
