I have the lemonade flavor from mister e liquid and it would seem as if it is getting condensation on the inside of the tank. It is as if the juice has pulp in it or something. I can make it go away when I shake it in all ways but it comes right back later. This is the first time I have encountered this but not the first time I have had a lemon flavored juice. I believe that I had a tank when I had lemon ice and it didn't do this. So is it suppose to do this or not?
