Thanks Refreshed! I have a question for you, or anyone else that wants to answer. I am getting ready to do a tubsoak. I putting epsom salts and hydrogen in it. I also have some domonite powder (don't know if I spelled that right). It's calcium carbonate powder. I thought of adding that recently to combat the fluoride that's in the water where I live. What do you think? And if you think it's a good idea, how much? I was thinking a tablespoon maybe?
