Low pH correction and acidity neutralization media

The pH (potential of hydrogen) level referrers  to the amount of hydrogen found in water. The pH level measured on a scale from 0 to 14 reflects how acidic water is. Seven is neutral, meaning there is a balance between acid and alkalinity. A measurement below 7 means acid is present and a measurement above 7 is basic or alkaline. The recommendation for public water systems is to maintain pH level between 6.5 and 8.5. Using Calcium Carbonate or a blend of magnesium oxide (Corosex) and calcite is the most common method of correction water acidity.
