First off i'll describe my set up i have an itaste VV set a 7.5W with 2.1 resistance from an iclear 30s. i currently have a thicker liquid and it seems everytime i refill with this juice i get a gurgling sound do i need to bump up the wattage because of the thickness of the liquid? i don't have any leaking from the tank at all i've done some research but most complain about the leaking and gurgling but i only have the gurgling. the hits arent bad the sound just makes me nervous as its the first time i've heard any tank do this without a leak.
