This will depend partly on what kind of physical shape you are in when you initially start drinking Ionized Water. For instance, if you have made a conscious effort to eat well and keep your body detoxified, you can start drinking Ionized Water at about a 9 on the pH scale.
You should begin drinking Ionized Water on Level One (between 7-8 pH). Start by drinking an 8 oz. glass of water slowly. If you do not feel any negative effects, try another glass later in the day. In three weeks, you can move up to Level 2. After drinking the Level 2 Alkaline Water for 3 weeks, you can move up to Level 3. Stronger Ionized Water is more alkaline, and contains stronger antioxidants that provide your body with more Oxygen.
