Need New CO2 Recipe

This has been asked so many times and I'm sorry to ask again but I need a recipe for my DIY injector. I have tried some different mixes and haven't been happy with any. I use wine makers yeast for the injector. I am just wondering if any of you have come up with a good working recipe for a 1 liter bottle. I have tried scaling some mixes down but haven't had much luck with bubble rate and they crap out after about a week. If any of you have a mix for 1 liter bottles, please let me know!

Gelatine mix

I was making gelatine blocks with Knox gelatine, using the recipe for Knox Blocks on the back of the box, but substituting 1 cups sugar and 2 cups water for the juice. After it set up overnight in the frdge in a shallow pan I cut it into 1" squares. Add enough cubes to get about 3" deep in the bottle, or maybe halfway, no more. Let that get back to room temp and add lukewarm water to a few inches from the top. Use wine or beer yeast, 1/4 teaspoon is enough. Keep the extra cubes in the fridge, sealed well, they will keep 4 weeks or so without molding. Should last about 3 to 4 weeks, sometimes more.

Do watch it at first to be certain it does not foam.

Just spotted this thread, has everything you need to know about C02. You'll probably find your answer somewhere in there.

Sorry I couldn't help directly,
