Water quality issues in a Hydroponic System

This question is from a guy who has been having trouble with his bubble cloner system. I have tested and proven you can successfully grow clones of your favorite plants with nothing but water. No chemicals or Hydroponic Fertilizer is necessary for the cloning process.

The issue he seems to be having is his water quality. His first problem is he used tap water which may be harming his cuttings.  The second is his PH has gone too high. The following is my response to him.
