No cartridges on a tank atty. The tank atty is designed only for tanks in the way it wicks.
Get a 510 atty, 510 cartridges, and a 510 drip tip. And buy the precut blue foam replacement stuffing for 510 at strictlyejuice.com. Cartridges sort of suck but drip tip and atty is great for testing juices.
(alternately you could use a fatter Ego atty and Ego cartridges and Ego drip tip but you would have to cut your own blue foam)
What most people prefer to cartridge + atty, at least for thin juices they like, are cartomizers aka cartos (screw on combined cart with internal atty, disposable). I can get a good week or two use out of a Boge carto if I use thin (20% or less VG) light clear juices (juices that leave little or no carto-clogging flavoring sediment). The most popular cartos on Ego are Boge 2.0 ohm (2.0 ohm is LR low resistance - uses battery charge faster and gives a hotter stronger hit). I use the Boge standard resistance cartos (2.8-3.2 ohm) because I move them between my Riva 510 (Ego clone) and my slim manual 510's and slim batteries should not use LR stuff. Boge are the most popular cartos and the standard resistance is good to learn on, even if you end up wanting LR.

How I fill Vapor4Life KR8 cartos and Boge 510 cartos
Pop out the soft cap with an unbent paperclip in the mouth hole, very careful not to catch stuffing or the wire loop.
Shake and open the eliquid
Hold a bit of tissue on the threaded end hole, tilt the carto, and add 18 drops per ml of capacity into the stuffing (Boges and most KR8 cartos are about 1ml).
Wait 15 seconds or so then see how many more drops the carto stuffing will soak in easily.
Clean up the threaded end, tilt open end down into tissue, puff into threaded end to clear air channel (Boges and the KR8 cartos I use have a defined center air channel and I want to see light through that)
Sop up any loose juice above the stuffing
Cap and let it settle - I lay it on different sides for 15-20 minutes to make sure every bit of stuffing gets damp so I won't singe the carto. if you use thicker juice than me (I use 20% Vg or less) then you may need to wait much longer.
While
vaping, if the vapor gets a bit light or a bit dry or the carto is getting hotter than normal, I take the carto off the battery and add eliquid. I sometimes use a plastic or delrin drip tip as a mouthpiece on Boge and KR8 cartos (not to drip into since the juice would head for the central air channel)
(Thumbs up!)
