DIY C02 Requirements?

Hello all, I'm trying to do the DIY Co2 system with yeast, but I have a question about the final diffusion part.

I have the 2 bottles and the tubes running to connect them, but for the diffuser can i just use this: http://www.amazon.com/Hagen-Natural-...7276177&sr=1-6? Or do i have to get an airstone / power head to diffuse it some more?

a co2 ladder would work for diy. might get better diffusion with air stone/powerhead... but the ladder will work fine.

According to this person:http://www.youtube.com/watch?v=Ry4IUaS4gIo who has the same thing i'm getting, says that "it took about a week until the bubbles started passing through at a smooth rate. You need to allow time for a bacterial slime to buil up on the surface of the CO2 Ladder." Is this true?

And, since I'm doing a DIY yeast Co2, should i worry about Co2 running over night? Or is there not enough Co2 being produced to harm my fish? As I am currently under the impression that you can run this type of Co2 all the time.

Also, I have a 20 gallon, and currently just have a 2 liter bottle for the reactor, and a 1 liter bottle to hold the water and extract the alcohol produced, is good enough or do I need more?

And finally, is this a reliable recipe for DIY Yeast Co2?:

1 teaspoon Yeast + 1 to 2 cup of sugar into 2 little bottle and fill in warm water untill 3/4 full ...
mixed and shake all the elements inside the bottel,when anaerobiosis reaction happen (wait 1 to 2 hours), CO2 will be generated.
more Yeast = More CO2
more Sugar = longest reaction

I would suggest not using a bubble ladder , its difficult to get enough co2 from diy as it is , and a bubble ladder is a very poor way of diffusing .

As long as your bottles are sealed completely, I would as well suggest a glass nano diffuser.
