Tapman, you're right: I am talking about two seperate gas tanks. I guess my quesiton could be simplied by saying, is there any reason I can't just unhook my CO2 tank and replace it with a mixed gas tank to nitrongenate my beer? And I think you answer that question above. Sounds like I can probalby just go get another normal C02 tank but have the gas store fill it up with a mix and try that. If it turns out it works well and I like it, I may just basically set up a whole seperate tap system and run one keg as C02 and one as mixed gas so I can have the best of both worlds. (I think the water thing is dead since I only have room for two taps (per the fiance) and that being the case, I don't want to sacrifice one to water
.
Thanks for your help!
