What juice are you using? This is how I get the most out of my nova. First, when you add liquid, you have to let it sit so the wick can absorb the juice. The thicker the juice, the longer it can take. If you fill it past the ml marking, it will produce very littler vapor until it burns the juice down to below the markers, so dont over fill it basically. When you first fill it, and before putting it on the battery, take a few strong sucks to draw juice into the atomizer. Also, always check the battery post for liquid buildup and residue, which can impare vapor production. I clean mine with a q-tip every time I refill. Make sure there is no juice on top of the rubber nipple thing too, as this stops vapor. If the top and bottom are dry, battery is clean, and the wick is saturated, the vapor will cloud any regular sized room (at least mine do and I have 6 nova tanks). I use VG juice from a variety of vendors. I wouldnt have modded it so quick, as they work great as they are if you know what you are doing, but it is a learning process. When I first fill mine, sometimes I get poor vapor at first, but I keep sucking and it gets itself going. This is when I usually overfill it or forget to clean my battery post.
