A while ago, we bought a Sodastream soda machine. We were happy for a while, until the sticker shock of replacing their tanks with a custom connector.
To avoid paying for that, I acquired a 20 lb CO2 tank that was attached to a Coke machine, so it is food grade etc. I bought an adapter for CGA 320 that fits Sodastream.
All good and dandy and everything forks just great.
The question now is, where to fill the tank. I guess that I can go to airgas, but it is not that close, neither to me, nor to my work. Any other alternatives?
Also, is there such a thing as food grade co2? Or can I get welding co2?
