So, I thought I'd try my hand at a the non DIY route for adding CO2. Just added a 20g CO2 cylinder and it lasted three days being only for only 10 hours each day. That can't be right? Or is it? If it is... forget this route!!
I was using 2 2Ltr plastic soda bottles. The unit was air tight. Each bottle has 2cups sugar to 1tsp - 1.5tsp of yeast. The bottles were place in there own water bath with its own heater kept at 70ºf and the bpm was set to around 30 and the drop checker was always in the green.
The reason for wanting to try a store bought kits was for the ease. I thinking of "manning up" and putting down for a proper CO2 regulator and a 20OZ CO2 canister/ paintball canister.
