That's how the protank2 is and it has been working great for a week now. Way easier to clean out than a whole wick, and the absorb time is much shorter. Since the protank2 is a bottom coil, the juice is all around the bottom, you don't need a long wick like you do with top coil atomizers, which wick the juice up like a straw. I am new too, but that is my understanding, somebody correct me if I am wrong.
I am not sure what type of tank you received, but it sounds like it is probably a bottom coil, if not then I would try to figure out how else it would be getting juice to the coil if not being wicked. Maybe some futuristic quantum physics stuff going on.
