I just got my first glass tank, I cleaned it up and filled it using the carto that came with it (2.5 ohm) and let it sit for about 45 minutes to make sure it's saturated. I'm using it on my eVic and I'm not having a lot of luck. When I use my clearos, I vape at between 10-11 watts, I turned it down to 7 and moved up to a 9 gradually. I'm getting hellacious dry hits, and now I can't the carto tank off, the tank just moves on the cart instead of gripping it and unscrewing it. I don't know if I should try another carto or what, but I certainly can't do much with it stuck on my PV. How can I fix this without damaging the tank?
