3 weeks analog free TODAY! I've been using Viva Nova's and clearomizers and decided to try a carto tank yesterday. I watched a nice instruction video on how to fill it...let's just say I'm not very good at following instructions and not only did it take forever, it got messy and I got impatient and I hit it too soon, which brought about a lovely burning Q-tip taste/smell, and then I over compensated and flooded the darn thing! I know, I know, operator error 100%! I know I did EXACTLY everything wrong but I am still curious as to why so many people prefer carto tanks?
