AlkaViva water ionizers provide, at the push of a button, water that varies from mildly alkaline to highly alkaline. This enables you to accustom yourself gradually to higher levels of alkaline drinking water (e.g. pH9.5 to 10).
You should start slowly with one glass of ionized water at the lowest alkaline setting and work your way up over several weeks to higher levels and amounts. If you experience any discomfort from detoxification, just move back to the previous level or smaller quantities.
This also allows different members of the family to dial up their preferred level. The highest levels of alkalinity are for cooking.
In addition, there is a button for water that is purified only filtered but not ionized. Its pH level will be close to the level of your regular tap water. This water is for those taking medications which should not be combined with alkaline water.
Remember: the pH level of ionized water will vary with the pH of your source, i.e. your tap water. In addition, if you wish to make the water more alkaline or more acid, simply slow down the flow of water, and the pH level will change by approximately a value of 1. A simple to use pH test kit is provided with every AlkaViva water ionizer, if you wish to check pH levels for yourself.
