When I refill, the bottom simply turns endlessly without becoming tight. This problem did not come on suddenly, it's just gotten worse over time, to the point that the nautilus leaks and the bottom is near impossible to remove.
Is it the silicone seal at the bottom?
Sorry, that was regarding Bigbells nautilus issue.
The top of the base has a silicone seal that seals the glass tank with the base. Note that the coil head has exposed threads that screw up into the tank 'chimney'.
There have been a couple of occasions where I had to apply a lil' pressure in order to start the head's threads. Just don't 'mule' too hard.
-Try a new uninstalled head (without base) and see if your 'chimney' threads are in good condition.
-Always install the head into the base 'goodentight' <fav German word>.
-Your tank should loosen before the head-to-base connection. IOW, your head should not come out of the base when removing the tank.
BTW, I've never had a Nautilus leak, ever.
Hope I made sense above. If not, ask away!
