Well I just started my diy Co2 prodject got a pretty good recipe for making reaction.

Recipe:
1. 2 Cups of Sugar
2. 1/4-1 teaspoon of yeast (more yeast = faster reaction = more CO2 for shorter time (2+ weeks))
3. 1/4 teaspoon of baking soda (optional)

I used a Oceanspray bottle, adjustable gang valve, airstone for a defuser, and airline of course. Experiment started i'll add 5ML of Flourish Excel instead of my typical 15ML, untill I can see the diy system working.

This is the address where I found my information

If you can find champagne yeast, it lasts a bit longer, but even with champagne yeast, mine usually peters out after about a week. I DO use a bit more yeast than your recipe, so that could be why.

Yea it's true I've been experimentingwith more and less. I think I've got too much salt in my tank for the cichlids my plants arent doing very well still? I'm a lil sad. Just gotta do some more research I guess. Congrats on the new project!
