Optimal Yeast Based Co2 Mix

[Revision17]

I seem to be in a thread starting mood tonight

Today I stumbled across this: http/www.beer-brewing.com/apex/brewers_y...t_nutrition.htm ; while looking up info on brewing beer.

Now, my planted aquarium is in somewhat of a limited area, so I can really only use the nutrafin container in my nutrafin CO2 kit. Unfortunately, I've been really lazy when it comes to measuring things when it goes into my CO2 mix. A dash here and a pinch there. I've been having decent enough results with using DI water (seems to work better than tap water.. guess since it's dechlorinated), baking soda, sugar, and yeast. Today, as per that page's info that yeast likes nitrogen in the form of ammonium, I added 2 drops of ammonia (which I had leftover from fishless cycling awhile back), and bubbles seem to be coming out faster than usual. Also, most of the nutrients listed in that page are things which I've been dosing in my planted tank, so maybe I'll use tank water next week. Also from that page, I see yeast likes vitamins, so maybe I'll add a bit of multivitamin to it week after next.

Also, I was wondering, would there be any interest in me running a "proper" experiment, with controls and everything measured somewhat accurately? I'm thinking that the measure would be by bubbles per minute from a set depth in water about 12 hours after the yeast mix is made.

Here are some of the tests I'm thinking of running (if I actually do this, I'll get measurements for this stuff, for now I just want people's opinions):
Control:
DI water (using DI since it will more easily be able to reproduced by other people)
Sugar
Yeast

Factor A: Baking Soda
Factor B: Ammonia
Factor C: Multivitamin
Factor D: Calcium Sulfate+Magnesium Sulfate (gH boost)
Factor E: Plantex CSM+B
Factor F: Planted tank water which has been EI dosed (highly variable, but may come in as a useful tool, since the water is so easy to obtain)

Tests (I'd really like to try out all combinations, but I don't think I'd have the time or patience for it):

1. A-F each alone
2. A+B
3. A+B+C+D+E
4. A+F

Any suggestions and/or criticisms are welcome

Also if someone has already figured out the uber mixture, by all means link/paste it

Go for it!!

I would want to consider why it likes ammonia, does it produce a different gas? If not what does it do to the yeast... I mean, you wouldn't want to poison the tank with any other gas.
