I recently moved to Sweden from the US (sorry for the English, my Swedish is terrible) and got set up with a kegerator. I purchased a CO2 tank, but I have no idea where to get it filled. In the US you usually had to go to a fire extinguisher service or a welding supply store, but by google translate-powered searching is failing me here. Where is a good place (ideally close to Södertälje or a train line) to fill a tank?
I do have the SodaStream adapter, but it really does not work well and I want to get back to a proper tank.
