Hey folks Even though I live in the city I am on well water, some of the smellingnest water before we clean it up. I don't think I want to put my highly softened water into the laser tube for fear of causing an arc. I have found a source for De-ionized water for just over $1/gallon. What do you use for your water, and where do you get it and are there any specific ingredients you put in it?
