What is a pH neutralising filter?
Many borehole water or spring supplies have a pH of less than 7. If your water supply has a pH of less than 7, it is considered to be acidic and must be treated. Acidic water can cause various problems, such as staining and corrosion. The water filter media used in a pH neutralising filter is crushed and processed limestone, called Magnadol. Magnadol can usually raise a pH from 6 to 7. The Magnadol dissolves into water as it passes through the filter and the natural alkalinity of the Magnadol (pH neutralising water filter media) raises the pH. Because of the calcium level in the Magnadol, the hardness of the water is affected. The hardness would be expected to rise around 50ppm.
