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 water filters down through the Magnadol filter media, up through a riser tube in the centre of the composite pressure vessel and out through the neutralising water filter control valve to service. Periodically, the pH neutralising filter will backwash, which changes the water flow through the water filter. The water in the backwash cycle flows in from the inlet down the centre riser tube, up through the Magnadol bed and out of the control valve to drain. See similar questions...

pH is a measure of the acidity ("sourness") or alkalinity ("sweetness") of soil. The scale ranges from 1 to 14, but few soils are more acidic that 5 or more alkaline than 9. A pH of 7 is perfectly neutral, but most plants grow best when the pH is a slightly acidic between 6.5. Soils in areas with low rainfall tend to be alkaline. Where rainfall is high, soils are more often acidic. This happens because rainfall gradually washes calcium from soil. See similar questions...

The degree of alkalinity of a solution is measured in terms of a value known as pH, which is tie negative logarithm of the concentration of hydrogen ions. On the Ph scale, which ranges from 0 (acid) to 14 (alkaline), a solution is neutral if its pH is 7. Our body pH should be slightly alkaline and should be approximately 7.5 measured via saliva or urine. Blood pH should be 7.365 ideally. See similar questions...

The acidity and alkalinity of a substance is referred to as its pH value. A neutral substance has a pH of 7, a substance with a pH above 7 is considered alkaline and a substance with a pH below 7 is considered acid. The term acidosis is used to describe a state of excess acidity in the body fluids whereby the term alkalosis describes a state of excess alkalinity. See similar questions...

All soaps are alkaline by their nature. The higher pH of soaps discourages microbes. That is why we only need to preserve with rosemary extract (for rancidity). Handmade soaps are 10.01. Castile Liquids 9.7-9.8 typically. Castile Gels 9.5-9.6 See similar questions...

Ph is the relative acidity or alkalinity of the soil. It uses a logarithmic scale which goes from 1.0 to 14.0. 7.0 is neutral. The lower the number below 7.0, the more acidic the soil is. Most plants like soil in the range between 6.0 and 7.0, except for really acid loving plants such as blueberries, or rhododendrons. Roses usually like soil best between 6.5 and 6.8. Alkaline soil above 7.0 can be very difficult to correct. See similar questions...
