• CO2 Generator?

    From Crows_32@yahoo.Com.Au@1:278/230 to All on Thu Dec 4 10:01:00 2003
    I have recently heard of mixing yeast, sugar, and warm water to create
    a CO2 Generator from the fermentation process. If CO2 Generation is
    the objective, can someone tell me what is the best ratio (for the
    starter mixture) of sugar:yeast:warm water to produce CO2?

    About 2 to 2.5 pounds to make a gallon. It won't work without yeast
    nutrient. Use EC-1118 yeast.

    I have used with good success the following:

    1 liter of warm water
    1.5 cups of sugar
    1 teaspoon of Red Star yeast

    I've experimented with adding small amounts of flour and/or baking
    soda, with no large difference noticed.

    That's what I'm wondering. Are these house plants to be grown in a closet
    by any chance?

    Aquarium plants, quite likely.

    We get funny calls like that at the shop all the time. Hell, I would
    recommend brewing beer for the CO2. Why not kill two birds with the same stone?

    If it has to be pure, you better pass it through a dryer and charcoal,
    too. There's more than CO2 in them gases.

    How about a lump of dry ice in a styrofoam ice box?

    Ah, sorry, I had answered without taking a good look at the newsgroups
    list. I'm reading this in the aquaria group, where CO2 injection is
    regularly used to aid plant growth in planted fish tanks. Some lucky
    hobbyists can afford CO2 tanks and valves and such, but many of us get
    along with just using a home-made setup involving a 2-liter bottle
    with the above ingredients, the CO2 output of which is directed into
    the fish tank.

    Are there any other by products that can cause problems for the fish/plants? How often do you use the generator, and for what lengths of time?

    What other gases are produced by fermentation, other than CO2? I've
    read a lot, especially on this newsgroup, about DIY CO2
    supplementation and there's never been any mention about other,
    possibly harmful gases.
    I use a Dennerle CO2 system. It comes with a bottle that contains some
    kind of sugar gel. All you do is add warm water and break open a
    capsule of what must be yeast. It's supposed to last about a month and
    then you're supposed to buy another bottle with the gel in it costing
    about ú4 or ú5. But after reading the posts on this group I do my own
    mixture of sugar and yeast and it works just as well. Saves me money.
    But now I'm kind of concerned that toxins may be getting into the
    water. The only purification in my system is that the CO2 is bubbled
    through a small bottle of water outside the tank before it reaches the
    v effective helter-skelter apparatus for diffusion inside the tank.

    Small quantities of other gases may be produced, but its nothing to
    worry about. Many of the aquatic plant "pros" (Karen Randall, etc.)
    recommend the yeast method of CO2 production. I have used it myself
    and have had no problems.
