I would pay ten bucks a fill if I new it was good air. I have had experiences with bad air and I would not go back to that shop. I now look for a certificate every time I get air.

I DO NOT want to meet up with a fungi that can thrive at 3000 Psig.seahunter once bubbled...
Mold will DEFINATELY grow in a scuba tank because there is a lot of air, hence oxygen available but, you'd have to be getting very wet air.
Like i said, i'm no biologist but it seems to me the stuff in the deepest part of the ocean probably slowly evolved to survive there. Take mold or fungus that typically lives at atmospheric pressure and subject it to those pressures and i think you would have dead ala pancake mold or fungi.seahunter once bubbled...
I don't know gedunk but they've found animals living and growing in the deepest parts of the ocean - no light, high pressure and very cold.
The story about the spit in the tank could be an urban myth but it's very old and it's a good shocker so I'll keep telling it.
Tanks have lots of available oxygen, moisture and warmth. Does anyone know if the pressure will prohibit bacterial growth?

The answer unless someone else has some tested ideas, is to allow 1/2 hour for your fill. Fill it slowly (less than 1000psi/minute) and then let it sit with regular top ups (every 5 minutes) for 20 to 30 minutes. Anything less than that and you'll have substantial pressure loss (more than 10%).
