DIY CO2 Great Recipe.

I add 2 cups of sugar to the 2 liter bottle then fill 75% of the bottle with warm water and shake it until it looks like most of the sugar has "gone away". Then I'll use a bowl, fill it with the yeast, add about a tablespoon of sugar, and 1/2 cup of warm water and mix the hell out of it. Let the yeast mix sit for 10-15 minutes to ferment, and once I see the mixture is covered with what looks like foam then I pour the mixture into the 2 liter bottle, and shake it up. Then hook up everything to my tank, and normally within about 30-45 minutes I start seeing co2 bubbles coming from the airstone. Works every time for me....

i read this on another thread but i wanted to repost it because it really works great, i used 2 other methods and they didnt work, used this one and within a half hour your getting co2. very easy and very good recipe

Hunter PS way seems a little bit more thorough. I did it almost the same way. Except I added a cup of orange juice.
