water, sugar, yeast and sometimes baking soda.

some of you all make too much out of diy co2, I would be interested if any of this stuff actually helps or if you just think it does....

Well, I have tried brown sugar and it is a longer, slower bubble production. good for some.

I have (3) 2 litre bottles of diy co2 all connected together "line" style and I get a pretty good bubble per second count.

I never use hot water, as close to warm as possible, maybe in the 80's. I want it just a bit above my tank temp.
If it is cooler than 100 I never need worry about killing it. It may take a few extra hours to really kick in but if I do it about 10am by 6 or 7 at night I have bubble craze.

and---always verify which direction your check valve is on. and then re-verify the check valve a little later to be certain.
