I recently bought a kayfun mini and I can't get this to work properly. I'm making sure the wick isn't blocking the canal so I know it's not that. I keep the air hole covered when filling from the top as I've heard it's much better to do it from there. Once the hole I covered I screw on the top piece slightly but the air bubbles do not flow up to the top. As I unscrew it a littl bit more then the liquid start to flow out so I'm unscrewing it too much at that point. There has to be a better way to use it. Please help as from what I've been reading once you get it this tank is fantastic.
