So I'm fairly new (a few weeks in) and I started using a kanger protank today. It keeps spitting juice into my mouth. Does anyone have any idea what I might be doing wrong to make this happen or how I can avoid it? I don't know if it has anything to do with the tank but I've not had this problem with the other two types of tanks I have tried previously. Other than that I really like this one, so any suggestions is greatly appreciated.
