I'm moving up to an APV and decided to go with this setup after doing some research on the forum. I have a couple of questions for the veteran vaping crowd. With some help from a forum member, I've decided to get the 22 mm tank in standard size and am going to use the boge pre punched cartos in standard and low resistance. Wanted to try the ikenvape but nothing is in stock. Want to use a flangeless catro so I can have the smallest gape between the mod and tank. My question is can you reuse the carto's with different juices by washing them out or is each carto only good for one juice? I have an evod and mini protank now and just soak them in alcohol to clean them out and try different juices. I'm at the point where I've tried a bunch of juices and am starting to find my preference. So far I like the heathers hevenly t, N.L. bounty hunt bounty hunter, N.L. gold and Allien Gorilla juice. Also, what exactly is this thinghy for from Ibtanked? Is there any good videos out there that show you how to set up, prime, clean and use the ibtanked set up? Any other advice would be appreciated as I'd like to order the Ibtanked this weekend and want to get everything I need. So far the best place to by the boge cartos looks like myvapor store. Last question, are you able to store used cartos that aren't spent and use them again later? Figured I'd get sick of the same juice after a couple of days and want to try something else. I really don't want to buy a bunch of tanks from ibtanked as they aren't cheap. I do have an evod, mini protank 2 and a couple of clearos I could put on the zmax, although it would look funny. Thanks!
