It takes time. I had a Red Sea version it took 24-36 hrs to start making co2
Hi Overgrowth,I have a dilemma. A long time ago I could make DIY CO2, but the last three tries I have failed. I tried again just a few minutes ago, and I know it's too early to tell if it worked, but I doubt it's going to bubble. Here's what I did:
1) Applied another layer of hot glue to the soda bottle cap and the air tube just to make sure there are no leaks.
2) Put 2 cups of sugar and 1/4 tsp of yeast in the bottle.
3) Filled a small amount of the bottle with cold water, and then filled the rest with hot water, to make it warm.
4) Added Prime.
5) Shook the bottle.
6) Hooked up to tank.
Right now I'm seeing the yeast particles just floating in the mixture. I'm pretty sure this means it's dead. And this was a brand new pack of yeast too! If I'm doing anything wrong, please tell me. Thanks.
I don't think that's the problem. Firstly, I put a little cool water in the tank before I put in the hot water to balance the temperature. After the bottle's filled up, the top feels warm, but the bottom still feels cool. Secondly, the water at its hottest doesn't exceed 90-93F.Hi Overgrowth,
I suspect that the hot water is killing your yeast. I had the same problem for several batches of DIY (when I was doing DIY). I found the trick was to fill the bottle with lukewarm (body temp) water then add yeast and shake. Also, I never connected my tubing until the bottle dropped to room temperature to avoid a suction occurring as the bottle cooled and sucking the water out of my tank.

The previous two tries I used colder water than the current attempt, but there were no bubbles.Are you using a new package? I would try again but use colder water, the initial start up would be slower but you wouldn't run the risk of burning the yeast & for the tubing to the cap I never use a glue gun.. I just can't get a good seal with it. I used to use sealant but I hated waiting long for it to cure so now I just use super glue...take the tubing & put it in about an inch then put superglue on the top around the tubing & pull down. Works everytime
This. Treat the yeast like you would if you're baking bread. It really helps to proof it first because it starts bubbling faster and you can double check that your yeast is alive.Put your sugar in your pop bottle. Fill the pop bottle with the warmest temp the yeast will tolerate (110 F). Shake to dissolve the sugar completely. Pour a small amount of that mixture into a cup (preferably pre-warmed but if it's thin walled plastic like a measuring cup I would skip this step). Sprinkle your yeast into this liquid and give it a gentle stir. WAIT UNTIL THE YEAST IS FOAMING. 10-15 minutes usually. Then add this mixture back into your main bottle. Add your pinch of baking soda now if you want to. Seal and go.
