    Question Glass laser tube cooling water

    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?

    Distilled water or Deionized should be just fine. I still have city water in mine after 10 months no issues at all.

    Do you dilute the RV antifreeze with water?

    Di will eat tubes with aluminium end caps on them, use distilled

    Avoid anything conductive as far as possible, water doesn't conduct, impurities in it are what conduct. Get that resistance too low and the arc will track to the coolant and blow a hole in the tube (the tubes resistance is actually really high so your are on the down low already before you start)
    You did what !
