Well, I just ordered my new provari mini over the weekend and was looking at putting a nice tank on it. I was reading another thread about the Ibtanks. I sent some questions to them but no response!! I have some boge cartos and some joyetech attys, do I use them inside the tank? I also noticed some holes inside the glass tank I am assuming on the carto....my cartos do not have holes....how many holes are needed as I guess again it is to keep the juice flowing. Anyway, any guidance on how to properly use the ibtanks and what devices I can use inside of them would be greatly appreciated before I make a purchase!! All suggestions welcome on other tanks as well as I know nothing about this subject!!
