I have the Atlantis Series Tank on my Joytech Evic VT. The first week i bought the Atlantis tank and used 12mg Nicotine five pawns signature series e-juice at with mod set at 25 watts with my atomizer at .54 ohm doing full lung pulls and getting amazing flavor with huge clouds. After almost 2 weeks I had to replace the atomizer and installed an "identical" .5 ohm and now everything tastes & functions terrible. All of my settings are the same as before & would like to know what is causing the burnt flavor and small clouds before spending money on more coils. Any input would be great, thank you.
