Hi, and welcome. You'll need a lot more battery for that tank, it's only subohm. You're going to need at the very least an iStick 30. A 50 watt mod would be better. If you want a good tank, look at the Aspire Nautilus for your current battery, it offers coils in the range your eGo battery can handle. ANother good choice would be any of several Kanger tanks. If you went for the Sub Tank, you could use the coils above 1 ohm on your eGo-- it'll still be a bit weak vape, that's not a lot of battery-- and switch to the subohm type when you buy more power. Let me also say you aren't going to get clouds with anything short of 30 watts or so, and even that's thin. Really, if you want to move up, you're going to have to upgrade battery and tank at the same time. The iStick 30 and a Kanger subtank is an excellent combo, or the Aspire Atlantis tank instead of the Kanger. You're looking at $45-50 for the iStick, plus the tank, though. Whatever you do, please don't put a subohm tank on that eGo.
