Another saying not to add old tank
juice back into bottle, Especially in gta type tanks where the wicks are in constant contact with
juice. All that popping and heat degrades the juice and turns it darker, so a big no no adding back to fresh juice....I also dont mix flavors without rewicking , but I keep a certain tank to a certain flavor anyways. 7 set ups, 7 different flavors atm....that to me is the best way to keep one from not tasting properly
