Filling up a Kayfun

[Tubbyengineer]

I use a raspberry menthol in my Kayfun which is pink too, I have the full clear tabk on mine so it's easier to see whats going on, but, as the wick starts to get dirty you get a layer of darker juice forming at the bottom of the tank - you should be able to see it in the standard tank window if you wait until the juice first goes out of sight then tip the atty on it's side, as the juice flows over the window you start to see "dirty" swirls in it once you do, change the wick...

I ended up changing it and it was all black from the middle already. I put a new piece of cotton but it seems to taste a bit funky I dried burned it before putting the new wick in...
