This is probably a very noob, uneducated question, but I'm wondering if I have to use a carto tank, whether it be glass, polypro, or metal for the citrusy cracking juices. I've been using a clearo up until getting a bunch of new juices and just like how easy it is.....fill and vape....clean out every other night....just so easy. Now I'm sitting here with lemon meringue pie and orange creamsicle, which I'm sure I can't just through into my clearo. I have a couple polypro tanks for these tough juices and have watched the video on how to fill it, not a problem. I'm sure I can do it...just wish I could enjoy these juices without always having to order cartos. If not, I'm looking at the mini vivi novas in metal so if you have experience with those I'd appreciate hearing how you like them. My batts are vision spinners. Thanks loads!!!
