Poll: What type of CO2 do you use?

Gelatine DIY

I'm doing gelatine DIY in two tanks and Hagen in the last tank.

I'm getting a month out of the gelatine, with a stable pH. Only moderate CO2 levels, but that is probably more due to the HOB filter than the yeast.

I will be moving to a larger one gallon bottle on the 29 G soon, just to see how much longer it might go, but it is all under control now so I'm done experimenting until after some holidays.

Currently, I'm using gelatine with 1 cup of sugar in a 2 liter bottle with baking soda and salt.

In a few weeks I'll set up a side-by-side test of champagne yeast, ale yeast, and bread yeast using gelatine only. When I have those daily bubble rates charted, I'll do it again with the same yeasts and baking soda, then again with yeast nutrient. theres a lot of different types of yeast nutrient so I'm not sure how many of those I might test.

anonapersona: I will be anticipating those results with baited breath!

Hey Anonapersona!

Anonapersona is the person over on the AquaBotanic board who inspired my yeast researches. He has a few long running threads on the topic and they're well worth reading for anyone interested in DIY CO2. I'm hoping he(?) turns it into an article at the end of the day.

I feel almost guilty for bailing, but there just isn't enough time in the day or sugar in the cupboard. Maybe I'll try one last batch while I'm assembling the rig.
