Talk:Standard O₂ Tank/@comment-25760938-20180226041218

For those affected by not being able to stack O2 tanks anymore: Each oxygen tank now shows the amount of oxygen it contains. When at the surface (or any place not in the water) you can take an empty tank and swap it with your current equipped tank to fill it with oxygen and store it for later use. It's a similar but more "controlled" method of O2 tank stacking, and it even makes a bit more sense.
