Just picked up your Atlantis tank yesterday and so far I'm just experiencing very "hot" hits. I have a battery that goes up to 50 watts. The guy at the vape shop I got it from was running his at 30 watts and .05 ohm.
I've tried from 7 to 35 watts and the hits are too hot to inhale and the clouds not nearly the size he was producing. I've also adjusted the airflow from lean to full flow without any notable difference.
