I purchased a DCT 1.5ohm tank online with some juice. Im new to this stuff so I found out it has a cartomizer in it. Well I have been using an iClear 16 clearomizer and it has consistently been producing awesome vapor. But when I fill up and try to use the DCT there is barely anything coming out at all. I really would like it to work well since the tank on it is much bigger, but right now i am very dissipointed with the vapor it is producing. What should I try to make it work better??
