Thanks for the advise guys. I've been digging into setting up C02, I want to buy it piece for piece instead of just getting a "kit". It is all very confusing. I will be buying a 10lb bottle, I'm looking at a Milwaukee regulator (Comes with dual gauges, solenoid, needle valve and a bubble counter) is this the way to go, or is it better to buy these parts seperate? I just want it to be as easy as possible. A set it and forget it type setup. And I want the pH monitor and all that as well. Any advise?
