Hi there,
I use two things to raise the ph of my water. one of them is Flanagan Microclusters which is highly alkaline. These make the water molecule clusters very very tiny and "wetter" so that they can pass in and out of cell much better. I use a particular product called Crystal Water but a Google search for Flanagan Micrclusters will work.
Also Prill beads are a reasuable mineral stone which will Alkalize water if left in for a few hours. This too makes the water "wetter" and smaller and raises the ph. I have heard prill beads described as making the water like DEW.
