From that description I would hazard a guess that the liquid disappeared into the cart. The cart itself holds 1 ml and probably soaked up that 1/4 full tank's liquid....which means it's time to add more liquid to the tank! This is the downside to tanks.....they can go thru liquid fairly quickly!
Sorry, I couldnt disagree more! I hope this isnt deleted...Im not a 'family' member. i do however (like SO many on ECF) swear by carto tanks. I use both 5 & 6ml tanks w/the standard or XL cartomizers. Ofcourse you have to PRIME the cartomizer with the 1ml Juice -if you dont-your just going to BURN the cart!!
So you've got the 1cc in the cart, another 5 or 6 in the tank. i've yet to see anyone really exceeding 10ml vape/day with tons of vape.
the main reason the carto tanks are so darn popular is that we can fill em and leave em. We're good for a long time.
Think about 1/3 of a 30ml bottle of juice. think about the 10ml bottles. Are you vaping more than that in a day?
***the most
important tip for noob tank users is learning to set up the tank the right way. If you
fry the cartomizer inadvertantly; toss it! It is literally "toast" and you cannot "unburn" burnt toast.
