I usually use vivi nova tanks but wanted to try something else so I bought a Boge F16 tank and filled up the inside along the sides w/o getting in the middle part and filled up the tank. I waited and then tried to hit it, it didn't produce a hit but tasted burnt. I assumed that it wasn't filled up enough inside so I filled the filler more, I finally got like two hit and then no vapor again. I looked at the filler and it looks dry again, so I am assuming it's not seeping through the prepunched holes. I have read great things about these and am at a loss. This is my first venture into this kind of tank. BTW I am using 65/35 pg/vg so I assume that the liquid isn't the culprit.
