Middle of the night last night my cell phone just went crazy with messages from my Apex. I have an alarm set when the PH of my reactor goes above 7.5. Meaning its out of gas. So I plan to leave work a bit early today and get a refill on my 20# tank. So it got me thinking. When i refilled last I just went to my local welding shop and bought a 20# tank. Cost me something like $25 and change. But is there a difference between that gas and something you would use in our application or in beer making? Basically, are there different grades of CO2?
