Why worry about it when air is so cheap from a local dive shop. You also have to worry about the CO₂ freezing and blocking valves as it expands since it has a much higher freezing temperature than air. You also can’t use it as a backup life support system.

Hi Guys. Has anyone considered using compressed CO2 for blowing ballast? It seems to me that a liquid CO2 tank would have a lot more volume than an air tank.Frank D.
