so about 3 weeks ago when i got into RDAs i put all my tanks in the little wooden stand that i have. i fell in love with dripping so i haven't touched them since. earlier today i looked at them and got nostalgic and just felt like having a casual vape out of some of my standard tanks and old devices. so i popped on my iclear pyrex tank and when i draw on it the draw is extremely tight and even a 10 second pull produces the tiniest cloud of vapor i have ever seen. alright whatever, i popped on my iclear 30b, same problem, kanger aerotank, same problem, nautilus on the largest air hole, same problem. aerotank mini, same problem....i don't understand how all my tanks got messed up. I'm assuming it has something to do with letting juice sit in there for weeks. maybe all the coils got gunked up? any ideas?
