New to sub ohm vaping

Hello everyone!i've been vaping for a couple of months now using the delirium v2 ecig but i decided to move on to something a little bit more advanced so i bought the innokin coolfire iv 100w mod with the isub v tc tank! as far as i know this is a sub ohm tank which means i get to vape with coils <1 my questions is since i have a sub ohm tank can i use coils above 1 ohm or do i have to buy another kind of tank for this model and if so any suggestions? Thanks a lot in advance
