I know this may seem like a silly question, but I was just pondering the whole notion of yeast reactions in a bottle or cyclinder and the co2 that is produced.

Does the rate of bubbles change with the temp?

For example, if I have two cannisters - one in a room that is 65 and another in a room that is 85, will the one in the 85F room run more bubbles per second?

I'm not interested in doing this, I simply want to understand if rate is affected by temp.

The fermentation process will speed up if you increase the ambient temperature. If you run DIY CO2, you can see the change in reaction by placing the bottle near a hot air register to see the reaction rate and then move it away from the register to see the reaction.

That's kind of what I figured.

Well, I'm 48 hours into my Hagen setup and it still hasn't started. It has one more inch to go before all of the water is out of the line. Yesterday it was 2 inches. I know the 69F has alot to do with it. Maybe I'll set the cannister on top of the light fixture for a bit today . I wouldn't want it to tip so I would only do that while I'm there, then I'm going to hang it again.

Are you using your own mixture or the hagen one...because I've heard that using your own mixture in the hagen kit can really speed it up.

Shaking the mixture also helps a little (releases gas).

wait.. u can use ur own mixtures in the hagen setup? im planning on getting Co2 once i get my 110w PC lighting.

Thanks for the tips.

I used the Hagen mixture the first time. They have an activator packet, which I know is yeast. There is a stabilizer packet, which I believe is baking soda. I have no plans of buying further packets as I know I can make my own.

I didn't want it to get started just yet. I needed to transfer some fish out into a 10 gallon and didn't want the pH change, so it worked out well. If it doesn't seem to be running too much, I'll try giving it a shake.

I'm still concerned with other fish or another rasbora getting trapped behind the ladder again. Any fish behind that thing, with co2 bubbles going up has got to be in trouble. Luckily, the one that got caught, did so before it was running.
