I see all these threads where people say that ceramic diffusers do not work with DIY CO2, but I wonder how many of these people have tried it.
I have used three or four Fluval ceramic diffusers with no issues. One brand, so it is more anecdotal evidence than anything else, but I really wonder if it is an issue of the pressure required or the construction of the set up.
I am pretty confident that the yeast will continue to produce CO2 until the bottle explodes (over 100PSI) or an airline ruptures or blows off of a fitting, some component failure. I have not seen anybody mention anything about this or warnings of exploding bottles with ceramic diffusers, so I doubt this is happening to people. I may try an experiment to see if yeast will build up enough pressure to rupture a bottle when the weather gets a little warmer if I can find somewhere to do this where it will not disturb anyone or freak anybody out thinking that somebody is discharging a firearm near the house. I do know that the pressure effects the fermentation process, but I do not believe that it will shut the fermentation process down.
I believe that the majority of people are either parroting what they have read or had a leak that was off gassing with the ceramic diffuser, but was small enough so that with a lower pressure diffuser it was not apparent due to the majority of the gas being expelled through the diffuser. This switching diffuser types and getting CO2 discharged into the tank could easily lead someone to believe that DIY CO2 does not work with ceramic diffusers.
How many people here have actually tried to run DIY CO2 with ceramic diffusers?
What brand(s) did you use?
How many people did it not work for?
If it did not work, did you run a full leak test with a bubble solution (simple soap and water)?
If it did not work, were you using a simple sugar and water solution, or was it a more complex mixture?
For me, Fluval ceramic diffuser with sugar, water, some molasses, and baker's yeast (I kind of eyeball it based on the contour lines of the bottle). I drill the hole in the cap 1/16" smaller than the airline (need to check that the hose isn't pinched off in the cap. Sometimes I have to open the hole up a little bit. It is sufficiently tight that glue is probably not needed), then super glue it in place from both sides and let it dry over night. I tried more complex set ups, but it was too much hassle and failure prone. This has worked pretty flawlessly for the past several bottles I have set up.
