I was using a brand of E-juice that was thicker.It worked good,lasted a long time between refills,just not having the flavor I was looking for. So I'm trying some other liquids and they are ALOT thinner,It seems i cant get a few good drags in and it's time to top off. What do you do about this? Is there something I'm missing here? Am I packing my carts to loose/tight (using fluval,tried blue foam and juice goes right through that) Whats the solution?
