    Anybody knows what is the best ingredient for DIY CO2?
    1 bubble per second or two will be good.
    I have just started one on the weekend with two litres bottle, 1 cup of sugar and 1/4 teaspoon of yeast. I don't know how long it will last.

    apparently you also need to add some baking soda.
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    1 bubble per sec is the max it will go, probably.

    DIY will be effective for abt 2 week or so.

    The ingredient you have aleady know. Sugar + yeast + water. Those that add baking powder is to increase the hardness of the mixture such that the mixture won't turn accidic so fast(which will kill the yeats and stop CO2 production).

    Hope this helps.

    does adding more yeast produce more CO2?? say like from 1/4 to 1/2 or 1 teaspoonful..

    yup! but shorter lasting mixture.
    once sugar is exhausted, no more co2.

    adding some more sugar will prolong it.. but since you are taking it to add sugar. Might as well make a new mixture.

    Any sugar can.. Any brand also can... Buy the cheapest type... Think white coarse sugar should be cheapest.

    Yes - using a reactor (especially the 3 bioball type) does wonders. The CO2 is not wasted. So far no risk of overdose and I did not pump air when lights off.
    My mixture of 2 cup sugar + 1 tsp baking powder + 1/2 tsp yeast can last a month. Initial bubbling is fast like 1 bubble/sec. When stable, the bubbling is about 1 bubble in 3 or 4 seconds. It tapers off at the end of the month to about 1 bubble in > 10 seconds.

    for 1 litre water, I used 2 cup sugar + 1/4 soda + 1/4 yeast (lasted between 2-3 weeks).

    More yeast = More CO2 = Short duration

    To make full use of CO2 (if you don't use a reactor), cut up a bottle and reverse it to "collect" the CO2 bubbling from the diffuser. CO2 will slowly dissolve. <-- this is good if you are changing your mixture.

    Lotsa examples in forum/web. Experiments to make your perfect ratio. After awhile, probably get tired of it and go for the real deal.
    cheers,

    If you find 2 cups of sugar is too expensive... You can try rice...
    Same effect... Cheaper imo... Dunno why have that feeling...
