I’d be interested to know where you get the industrial tank too. I read it needs to be food grade.

I wonder why no one has made an open source Soda stream that connects to the big tanks right out of the box in a thoughtful way. Or better yet, a system for refilling the sodastream tanks from a large canister so that the sodastream can still sit easily in your counter.

Not OP, but in my experience you can pretty much always buy food-grade CO2 tanks from homebrewing shops. They usually do refills and exchanges too, as well as selling all the hosing and gaskets and clamps and whatnot you'd need.
