Hi. I am starting to become very frustrated as to why my diy co2 setup is not producing co2. I'll tell you exactly what I do, so that you may be able to find my flaw.

1. Get 1 liter gatorade bottle.

2. Fill up 3/4 with lukewarm water.

3. Add 1 cup of sugar.

4. Add 1/2 tsp of baking soda and shake bottle until sugar is mixed.

5. In a different container activate yeast by adding a little lukewarm water and 1/4 tsp of red star active dry yeast.

6. Stir/wait for 10 minutes.

7. Pour active yeast into sugar/water/baking soda mixture.

8. Attach to co2 diy.

After I attach it to the co2 there are no bubbles at all except some on the very bottom. Am I doing anything wrong? Any help would be appreciated.

Seal the hole with silicone. No doubt any gas that is being produced will be escaping. Also, is the pipe co2 proof?

The pipe is made out of silicone, so I assume it is. :)
 
try; put sugar in bottle, add yeast and same amount of baking soda. add tepid water. Connect to tank. Do not shake.
 
I use a nutrifin co2 cannister with a home made concoction in it, get no provlems so you have two things:

1) tepid water. 1 part boiling to 2 parts cold ought to to it. I use this same mix to react yeast in dough making.

2) your mixture bottle looks like it pinches the tube a fair bit. Difficult to tell though. Seal all the tube to bottle top connections. Lastly having a 2nd bottle, you need to allow pressure to build up in both bottles. Any leaks will seap out that way instead. Try connecting just your mix bottle to start with to see if you are getting output (sgould see this within 4 hours)

Thanks!

1) How much is a 'part'?

2) Ok I am about to try that now. Should I seal the inside of the lid too? I would imagine just the outside is enough.
 
A part is whatever you need it to be e.g. if its 50ml boiled water its 100ml cold. Or if its 200ml hot its 400 cold.

Thanks, I don't know why I didn't think of that. :S
 
Oh also inless you are very dextress, just the outside otherwise you risk causing problems with the threading of the cap to the bottle.

Ok I am leaving the inside with no sealant. I just moved around the tube from the bubble counter --> tank. Co2 bubbles came out! That means there isn't a leak. Is it just building up enough pressure to get to the water? I just replaced that tube so there is no check valve on it. I think that may have been the problem.
 
Seal the inside too and once the outside has dried, wrap electrical tape around the silicone to strengthen it so that when you make the new mix the seal doesn't break.

Ok will do!

Just made a bell out of an old medicine cap, a suction cup, and some sealant. The bell is my best option because the co2 doesn't have enough pressure for anything else. Also it comes out at a rate where no co2 will be wasted. :)
 
The Nutrifin CO2 wws easily one of my best purchases. Cannister, tubing and diffuser for £9 and i use home brew mix in it. Made life wayyy neater looking and simpler.
 
i know everyone says seal it with silicon but i found that it just slips out of the pipe when changing it... it might just be me... im using bungs for wine making with the top of an silicon tube attached. (seems to work for me)

i'll take some pictures if you want?
