I still dont see any bubbles!!! Its almost 24 hrs... I did everything what the tutorial said..... HelP!!!

As suggested in my earlier PM to ya, check for leaks around the cap area, and make sure the yeast is still good. Since you're not using a glass diffuser or anything at the end of your airline tubing, we can take out the lack of pressure to run those items out of the equation. That leaves us leaks and bad yeast.

You can test the functionality of the yeast by putting it in a coke bottle and sealing it aff completely. It will pressurized the coke bottle in a few hours indicating that Co2 production is occuring and the yeast is good. And you can check for leaks around the cap with a soapy solution to look for soapy bubbles from the leaks.

What do I do after I put the yeast in the coke bottle and seal it off completely (no hole in cap)... Meaning how do I check THAT if it has pressure or not b/c I wont be able to squeeze the bottle.

What do I do with the soap solution and water? Sorry im new to this.

Currently I just squeezed the bottle and bubbles came out of the tubing....

John N.

If the bottle is seal off completely, the bottle will get harder and harder to squeeze because the yeast reaction creates CO2 gas that will fill up the open air space. This tells you the yeast is still working because it's making the gas.

Once you figure that the yeast is good, you can proceed to figuring out if you have leaks.
This is the way I would do it.

1. Mix the ingredients in the bottle.

2. Cap the bottle with the cap with your airline tubing through the top of it

3. Tie off the end of your airline tubing, so that no gas can escape.

4. Make some soapy water (make it similar to the toy bubble blowing solutions)

5. Take that solution and wipe it around the connection (cap area) and see if there's bubbles coming from those areas. In addition, since the tubing is tied, the bottle should feel pressurized (hard to the touch) indicating no leaks.

Once you figure out you have no leaks, and that the yeast is working, you are good to proceed.

Thanks for the info!

Well there is definetly pressure from the bottle. Every once in a while there will be a spur of bubbles that come out of the airline tube.. then it just stops... then picks up again later.... Is this normal? Or is it supposed to have a constant flow of bubbles?

John N.

That's normal as it starts up. It will be erratic, and then will be constant, shooting out 1 or 2 bubbles every 4-5 seconds.

This takes about a day or two, and after that, it will be constant for about 2 weeks, and then will become erratic again as the yeast eats up all the sugar. That means you should being to replace it.

YAY.. so its working.. lets hope it will keep it up... Im going to attempt a 1L mixture after work today.. with 1 cup sugar. 1/4 tsp yeast...

troybernard

so what do you do at night when the light in the tank is off and the co2 is still going. do you have a pump that you plug in?

jlui83

pump? no... I just let it run just like I would during the day......
