So, FYI to folks reading this in late 2017 ... Subnautica has reverted back to only using the tank in your paperdoll. But, you can carry multiple tanks in your inventory and manually swap them out. When you swap them out underwater, there will be a little air loss, probably to account for hooking the spare tank up to your suit. (eg: a tank may be loaded with 90 air, but if you swap underwater to it you'll get like 86 air or something).

When you go to refill air (at surface or in base or seamoth/prawn/cyclops), you'll need to manually swap the tanks out to let each refill, also.

Tanks still weigh something and can slow you down. So, lugging around 4 spare air tanks will still take up inventory space and slow you down.

But, you just have to manually swap out the tanks now on your paperdoll.
