Plans? We don't need no steenkin' plans!
Poke a hole in the cap of a 2-liter soda bottle, insert some tubing and
seal it with aquarium sealant. Wait a couple of days for it to set. Put
1.5 cups of sugar, 1/2 tsp. yeast and a pinch of baking soda (optional) in
the bottle and fill to the shoulder with warm-not-hot water. Shake
vigorously. Screw the cap on the bottle and insert the other end of the
tube wherever you want the CO2 to go i.e., filter intake, powerhead,
airstone, diffusing chamber. Wait an hour or so for the bubbles to start.
Lasts approximately two weeks.
If the bottle is going to be lower than the tank, for instance in a cabinet
underneath, you probably want to put a one-way valve on the tubing.

Hey folks, I built my DIY yeast co2 injector for my 63 gal tank, it
works
great! just used a 2 liter bottle, tubing, fine airstone w/ check
valve...
Each concoction produces co2 for about a week and a half... I am very
happy
with it
So here is my question: Does anyone know of a good or common place to
get
a
blow valve? (I.e. a valve that will discharge within a certain PSI
range)
I
would like to make my DIY system fault tolerant, but I am just stumped
on
where to get the blow valve... any ideas? Thanks!
