I posted the question a couple of days ago about changing out coils cause I change my juice through out the day and after help from this wonderful group of people I decided it was better just to have several tanks on hand and some extra coils. Now my question is since I have a dedicated tank to all my favorite juices that I use daily and few back ups is it bad to let them set in the tanks for days? Will it do anything to the e liquid or am I just overthinking all this too much like my husband says? I have a few in a tank that I may or may not use daily and it maybe 2 days before I touch that one. Any help on this would be very helpful. I most of my juices at 50/50 blends and they are mostly from MBV a few from a local vape shop but mostly MBV and don't want to ruin any of them since I am on a month to month orderer,
