Quality of CO2 Over Time

[mohgui]

i've got a question to ask... will the quality of CO2 deteriorate over time if not in used? if it does deteriorate, will it 'poison' the water if used?

i got a tank which is not in used for more than 6 months and was wondering if it is safe to use.

nope.
it is safe to use your tank.
