    I may be picking up a really old (last hydro. date of 5/89) Co2 tank tomorrow for cheap.
    I plan to trade it for a recently tested tank.
    It's nearly full though and I have no idea if it actually has Co2 in it or how long ago it was filled. The only sticker on it indicates it's Co2.
    Does anyone see a problem using really old Co2 gas in the fish tank?
    Does it draw moisture?
    Could it have any contaminates from the inside of the tank?

    I would be careful since it has been so long since last inspection.

    I would dump the gas personally and get it inspected and filled.

    Why take a chance?

    I would also be careful with using the old CO2 tank. The gas itself is probably fine, but I would be more concerned about the structural integrity of the CO2 tank. These things can go off like missiles, so why take the risk?
