Hi, I got what I figured out to be a vivi nova from a local place called vapor shark. I've had it for a month now and recently I noticed that the clear liquid I put in the tank is getting brown as I use it. Gets darker brown as it goes down. I put a new head on and its the same thing. Is it normal? Thanks

Yes, this is normal. The nicotine in e-Liquid will oxidize and turn brown after some time of exposure to oxygen.
MiamiMom63 Ultra Member ECF Veteran
Yes, what Tepid said is correct. Also, keep in mind that you are cooking your juice in a warm small area every time you Vape. So after awhile instead of poring in new fresh juice over some darker cooked juice and when it gets low, just por out the dark stuff and refill fresh again. At least, that's what I do.
