pH level is a measure of how acidic or basic water is. The range goes from 0-14. A level of 7 is considered neutral. There is a 10 fold change in pH per level, so a pH level of 9 is considered to be 10 times more acidic than a pH level of 8. Above 7 is considered acidic and below 7 is considered alkaline.
The reason the pH level is so important is that it is a clear indicator on if there is chemical change in the water.« Back to Glossary Index
