cool, i get a lot of really tiny bubbles out of the 50cent airstone on the end, probably about 1mm size about 10-15/sec.
DIY CO2?

Found this thread over at APC. Really cleared a lot of things up for me....and gave me too many options!

Sorry, but No. Once the EtOH reaches ~10%, the yeast will start to die off. The thought behind putting baking soda in there is to minimize the dropping of pH, which is a natural consequence of anaerobic fermentation. Baking soda will help ameliorate the pH, the problem is that the Na ions are probably harder on the yeast than the change in pH is, so it it counterproductive (so says a good source found when helping a daughter research this for a science fair project).
The protein and other "yeast feed" additions may have merit, but baking soda probably does not.
In order to have the sugar run out at about the same time as the EtOH concentration gets to be a problem, you should use 1 part sugar, 3 parts water (all by volume). This ratio gets you the best balance between longevity of the mix and efficient use of the sugar.
PS - try to locate the $0.50 airstone so that the bubbles get swept downward or sideways by filter or powerhead current - if the bubbles rise & pop, you're wasting CO2.
I may have to get something to diffuse it throughout the tank. Currently I only have a Dirtmagnet Senior sponge filter and a heater in the tank. I think powerhead would be overkill on this tank since its a 10g.
So putting the CO2 tube to a power head dosent do much? Its better to hook it up to a air stone and put it under the pump so it can blow tiny bubbles across the tank? Right now my CO2 it hooked up to a power head and its blowing out big bubbles and the big bubbles go right to the top of the tank when they just come out.
Sponge/Powerhead filter combos can be used - run the CO2 line to the bottom of the sponge, or just poke it into the sponge a bit so that the suction forces the gas to diffuse through the sponge.
Or - run it in reverse, with the CO2 into just a basket, with the sponge mounted firmly on the outlet. These will require more frequent cleaning as there is less surface area for chunky stuff to collect on, but it would also work, probably better for CO2.
