I'm pretty new to all of this and I keep hearing about atomizers (sp?). Do I need one of those in order to use a tank?
No generally atomizers are now only used for testing new juices.
If so how long do one of these cartos last?
You're eGo is 510 threading. The carto+ tank in your link is also 510 so it will work/ fit.
When I use a carto+ tank before tight draw begins I get- YMMV:
dark juice- 50- 60 ml
light juice- 80-90 ml
Do these cartomizers for tanks have the material inside that absorbs the liquid?
Here's a detail pic of a cartomizer:

Different delivery systems:- note
bolded Atty, Carto, etc is the abbreviated form
Red bolded is the parts that are in a carto+ tank system
Atomizer/
Atty- an element on to which 3-4 drops of juice is dripped- usually used for testing new juices because Attys are easy to clean. There are some diehard Atty users because it’s the best vape possible but very time consuming.
Cartridge/
Cart- a container with sponge (filled with juice) that is used with the Atty- juice drips on to Atty from filled cart and is vaporized- older outdated first “tank” system and prone to leaks unless the user is willing to buy extra seals and “fiddle” with them.
Cartomizer/
Carto- metal tube with stuffing and element. Holds anywhere form 1- 4 ml of juice. Carto is fully saturated and must be occasionally refilled when juice runs out. My Cartos last 1-2 weeks. Best Cartomizer I’ve found is the Smok Tech XL 1.7 single coil. Boge 2.0 ohm cartos will give a cooler vape. Always use single coil cartos with 3.3- 3.7 PVs for the best vape.
Carto+Tank- a Carto with a hole punched in it. Carto is than placed in a glass, metal or plastic tank which is filled with juice- juice saturates Carto by way of hole in Carto. My Cartos with a tank last, before tight draw occurs: light juices- 80-90 ml. dark juices- 50-60 ml.
Clearomizer (includes the Stardust and the Vivi Nova Tank)- a plastic or metal tank with a wick and element. Contains NO stuffing. The rebuildable clearos come with heads (coil+ wick) that can be cheaply and easily replaced. When the head burns out simply unscrew the old head out and screw in new head- takes 10 secs. My Vivi Nova heads are lasting about 6-8 weeks BUT I wash the heads every few days. I've found the Vivi Nova to give the best draw.
