First of all, sorry, but my polish so far is not good enough to post here. Przepraszam! I just wonder if anyone knows of a good co2 supplier that is 99.90% pure (food grade) in this area. I used a place near where i live (Lubasz) and I have been getting headaches, so I am worried that the co2 is not pure enough. Does anyone here know where to refill co2 bottles with pure co2? Dziękuję bardzo!
