Is there a problem with opening your Nautilus tank?

If you are having problems opening the Nautilus tank, try using a rubberband to help with the grip. If not a rubberband, if you have one of those rubber sheets to help open jars that works too. You just need something to give you grip. Remember to try to avoid pliers it's possible to somehow bend something out of shape. The rubber band thing is cheap and really does work. Just wrap it around the bottom piece and use it to grip as you try to unscrew it. Hope these are helpful for your vaping. Good luck and enjoy the Nautilus Mini which is really a great little tank.
