The DIY CO2 generator is simplicity itself. A half gallon (2 liter)
bottle with a small opening (glass is preferable), a one hole stopper to
fit (a drilled air tight lid will work), airline tubing of proper length,
an optionalairstone, one cup of sugar, one liter of water, and 1/2
teaspoon of yeast. Those are the basics. Mix the water, sugar, and yeast
in the bottle and place the air tight stopper (must be checked for leaks)
with the tubing leading out of it into the tank with the air stone. In
and hour or two you will have bubbling CO2. Most hobbyists trap the CO2
in a container to keep a constant interface between the gas and the water
rather than let it escape. An alternative is to bleed the CO2 into the
intake of a canister filter to keep a water/gas contact as long as
possible. Let your imagination and ingenuity be your guide as to what
works best for you. The idea is to let the CO2 dissolve into the aquarium
with as little wastage as possible. Gleaning through the archives and the
FAQs of this list will net you a large amount of information and
variations on this theme. www.cco.caltech.edu/~aquaria/Faq/
