That's a very interesting article. Earlier today I added some more crystals to my water including lavender amethyst, amazonite, rhodochrosite and Lapis Lazuli. Now I am thinking about inserting a few quartz crystals into the filter of my Waterwise 9000 and seeing what effect that would have on the taste and quality of the water. As I write, I am preparing a batch of unfiltered water, so the experiment must wait until tomorrow. Good idea or bad?
