Hey there! To get more oxygen, your first stop should be upgrading your Oxygen Tank. You'll want to craft a Standard O2 Tank first, then go for the High Capacity or Ultra High Capacity O2 Tank for even more breathing room. Good luck exploring those deep waters!
If you're swimming around like a fish, look for those big brain Coral Tubes. Slice them up with your survival knife for easy extra oxygen. Who needs a tank when you've got coral?
In my experience, you should prioritize upgrading your O2 tank and craft spare ones. This saved my life more times than I can count when exploring those deep depths!
