I just got a vfeng snowwolf with an athos tank. Right out the box I have had leaking issues. I have tried the close the air flow and fill, turn upside fix, and while it works about 50% of the time, the other 50% i still have leaking. Also it will leak randomly while im in the middle of a tank. Do I have a defective tank or is it just the nature of the beast? I have had other tanks, most noteably my Smok Baby Beast Brother and have NEVER had this issue.
