This may be kind of a dumb question but aside from the limitations of the tank's structure (cracking, etc.) how long can you leave air in a tank and still breathe it? I don't know what would change about the air. I forgot that my tank was still full from late last summer. Would it be best to empty it and have it refilled before diving or is the air okay? I have all the inspections up to date. Hydro and visual were done last July. Thanks, Phillip
