I'm surprised more people haven't commented on this idea. I'm just starting out with DIY CO2, going to try the traditional method vs this one. Looks interesting, albeit a little more time consuming. Thanks for the step by step!

Whats the jello for? sugar?

If i put the yeast with the jello before it sets, will it become marshmallow? This one I'm gonna try.

When we make sourdough bread, we feed the starter with sugar and instant potato flakes. The instant potato flakes are much more readily broken down as a food source for the yeast. Might be worth a try to see how it works in comparison.

Wonderfully simple and well "stepped" out. Thank you for sharing.
Two very quick questions:
1) when you add the baking soda is it to you liquid yeast brew that you are activating or or you sprinkling it over the jelly cube in the bottle before you pour in the activated yeast?
2) it there any liquid in the separator bottle? i am assuming there is to have a water chamber type filtration effect? Then again you know what happen when you assume.....

Thanks heaps mate

There is no water or anything in the separator bottle. I suppose you could add water, and call it a bubble counter.

The mix from the large jar can send some gunk through the tubing. This gunk comes out into the separator jar. Then the CO2 (and no gunk) goes from the separator jar to the tank.

I make my separator jar a bit different. The tubing in and out are the same length (pretty short, maybe 1" into the jar), then the tubing that comes from the yeast gets a short (2-3") piece of stiff tubing added. I have a lot of this stiff tubing from under gravel filters. The original use is to connect the air bubbler/stone to the air tubing, but keep it more firmly in one place with the stiff tubing.

Hello,

Nice little system. My only concern is that the bottles you are suggesting are not normally used as pressure vessels, like soda bottles. This is particularly true for the caps.

The problem being is that if you experience a clog in the tubing, you may also experience explosive results with the bottle. It could be dangerous to have a Co2 generator explode, but mostly it just creates a sticky gooey mess and your home smells like a brewery for weeks.

Just a suggestion from an old poster.
