I would say it is probably one of those "why risk it" things. Copper
tubing is fairly resistant to corrosion, but one of the things that
can cause pitting in copper water pipes is acidic water with high
CO2 content. Although you have a gas and not water, I know my set-up would
often have condensation build-up in the line and I imagine that could
easily work its way into your tank.
Personally, I don't think it would be worth the risk. Any particular reason
you did not want to just stick with plastic tubing?
