Close airflow when refilling also leak?

i think its very important to close no matter what,cuz when u filling and closing your top cap,it build pressure inside your tank,force those liquid to leak out...
when my tank leak on me,i always try more cotton,but keep same amount of length

try to flip the tank upside down before properly screw down the topcap to avoid from the pressure pushing the juice through the airhole...i dont have tornado nano but this is what i do for my previous supertank...

Not sure whats causing ur tank to leak but mine cincai2 wick also didn't leak. I just make sure enuff 'cotton dlm lubang' and tis monster wicks like a champ.
28g s/steel, 9wraps @ 3mm x2
30/70 mix.
I do not close the afc when filling. Just like with my Bellus.

Jeles dgn abam ekudz menang auction.

So I tried my own luck lol. Today's haul:



Fairly interesting flavour profile too.

RM60... quite decent for an imported bottle of 60ML. Plus first try summore lol.

Also, as I CODed, also managed to test both Lava and the Mango one first before choosing, and the Lava was a lot more ADV in my book.

Can't wait for the next time something interesting pops up.
