I'm in search of finding out how often protank coils need to be replaced? Thanks!

It really depends on use and the type of juice you are using. Thicker juice like 100% VG is going to clog the wicks faster do to its thicker viscosity. Which will mean you will have to replace or clean the coil head soonerI'm in search of finding out how often protank coils need to be replaced? Thanks!
Who know... I have bought the Protank and the Protank 2 and both of them always leak some and gurgle with no vapor no matter what I do... even if they are full... wonder what I'm doing wrong?
It was a dark colored liquid which I guess clogged it quicker.
I'm "new" and really don't have the time or know how to try to clean it although I wish I did!
It just seemed easier to ditch it and put a new one in which fixed my dilemma but didn't know if that's normal.

Really seems variable, I always see the response of "about a week" intermingled with "about a month"
I guess you just know based on the quality of hit you are getting?
I'm not sure if someone helped you on this but I had the same problem. I changed out the coil and it fixes it right up. Ive heard that Due to poor quality control there are a quite a few defective units that came out of the factory

Thanks for the Dry Burn Instructions! May I ask, on the Vivi Nova, how you would replace the coil or wick? How do you pop out the coil so I can try out my own wrap on it?About a week with no cleaning, about a month with regular cleans / dry burns
Pretty much. When the vapor production goes down and the flavor is lessened, it's time to change or clean the coil head.
Saying that, every 2-4 tanks I just rinse mine under the hot water faucet regardless if I am getting less vapor or flavor - I also give the tank a rinse too, maybe a wipe with a q-tip. Every few days I'll do a dry burn to get the gunk off the coils. It actually takes longer to type out how to do a dry burn than it does to do one.*
With a little TLC, coil heads can last weeks and weeks - even vaping a 100% VG juice.
