Hey everyone! New here and pretty new to vaping in general. For reference to my question, I am using a Uwell Crown tank on an eVic-VT. In the process of trying tons of juice flavors, I've discovered a few that I really like BUT when I want to change flavors, I go through a hell of a process to get rid of the previous flavor as much as possible. I dismantle the tank completely, remove the coil, rinse the tank pieces individually, dry everything thoroughly, reassemble (sometimes swap out the coil, sometimes not - as these can be pricey), fill with juice and *finally* return to vaping. There has *got* to be an easier way to switch flavors! It got me thinking.. to keep things simple, and mainly to keep my flavors separated and true and not mixed in the same coil, I'm wanting to have one tank/coil setup for each flavor.. so I can simply swap out flavors by just swapping out to a different tank. The idea would be to have multiple tanks setup with coils and juice ready to go whenever I'd like to grab them. My concern is this.. are there any known issues with letting a tank sit with juice in it? I'm not talking for weeks.. I'd be swapping out and using each tank every few days or so, so they wouldn't be sitting idle for a long time. Just curious if there would be any problem with this approach?
