@Matheous I am unsure as to your motivations for wanting more alkaline water. Is it because you believe that it offers greater health benefits?
If so, you should note that this idea that more alkaline water can confer a range of health benefits is not supported by science. For example, a review of over 200 studies into alkaline water and bone health, published in the Nutrition Journal in 2011 found no benefit.
Various parts of the human body are designed to work at differing pH levels. Take the stomach, for instance - pH 2 ish. Blood is around 7.4 ish. The body is regulated and buffered, so even drinking strongly alkaline water will not effect the pH of your blood.

If it is for any other reason - ignore all of the above :)
