Hello
@boromichael and welcome to POTV.
I'm assuming you're referring to the Zeus Sub-Ohm tank and if I remember correctly you have the 0.2ohm and 0.4ohm coil options.
So you're probably best with an eliquid with 70% to 80% VG and I'd suggest 3mg Nic content.
My own personal recommendation would be to have a look at
Prime Vapes for some excellent eliquid.
They make some amazing flavours, are a highly respected vendor on here and Lee is a great guy.
Also when you have a few minutes you could browse through MrDJ's
