Oxygen Tanks
A diving tank is a tank that has pressure breathing gas. While diving it gives you the gas through a regulator. Tanks can come in a variety sizes. Low pressure tanks are a bit larger and high pressure tanks are slightly smaller. You can get a tank in Steel or Aluminum tanks.
Aluminum tanks are more common than their steel counterparts. They are a bit cheaper than steel and can last longer. Make sure you have some added weight when diving with an aluminum tank. They can tend to float towards the end of dives.
You can also get stickers and extra valves for your dive tank.
