I just got a Russian 91% yesterday, and it's great. I'm vaping Jameson Peaches and Cream right now, and I just realized that this juice could be acidic. I don't want to the tank to crack. I tried using the metal tank window instead of the plastic one, but I cannot for the life of me figure out how to put the right amount of juice in. Is there any way to tell if I'm over filling and flooding?
