I searched but couldn't find a thread about this, although I'm sure I remember seeing one last year?
I have two Al80 tanks that were a gift. They were filled when they were VIP'ed July 2010. Is there any reason to NOT go ahead and dive these before I take them in for a VIP in about 2-3 weeks?
Is there really such a thing as "old air" in a properly maintained tank? I can see that if there was corrosion, that the O2 content might be down (in addition to the oxidation byproducts), but is the a real concern?
