Since I have had CO2 mix all over the place, I'll try to answer.

As long as you don't try to keep the CO2 mixture under pressure, you don't have 
to worry about exploding bottles or "mad firehose" tubing.  

I use 2 cups of sugar (.5 liters), with 1 tsp of yeast (2 ml?) and 1 tsp of 
baking soda in my yeast generators.  The bottle is a 2-liter soft drink bottle 
with a fitting in the cap for the air line.  I fill the bottle to within 3" (8 
cm) of the top with lukewarm tap water.  After hooking it up, I start getting 
bubbles within 20 minutes, and I get full strength in about 1 day.  It 
continues to bubble for about 3 weeks, but I like to change out the mixtures 
every other week.  I run two bottles on my 55 gallon tank, alternating the 
"freshening" on the bottles.

One hint:  Leave the bottle cap hooked up to the air tubing.  Don't bother to 
remove it.  This is just to good of a place for leaks to occur.  I just unscrew 
the bottle off of the cap when I want to work on it.

Hope this helps,
