Just buy a maxi-jet 400 ($16), drop your CO2 in the air inlet port and be done with your problem.

yep 1/4" no blockage. I guess i'll just leave it and wait for a week or so, it just makes no sense to me.

yeah, i was surprised because everything there is more expensive compared to petco and petsmart. I spent $3+ on one stinkin male guppy versus $1.50.

Just wanted to say thanks for the tutorial! I had forgotten completely that fermentation is an excellent source of CO2.

If anybody out there is interested, here is a tutorial on how to make a little device to count the bubbles being put out by your CO2 generator. (No, I'm not the author, but it looks like a fun project!)

Angry Re: DIY CO2 made easy

Ok I don't know what else to do besides remove the Co2 from my tank :( I redid my co2 on my tank because it stopped producing. I added 2 more bottles (3 bottles with a bubble counter) I resealed all the tubes and let it cure for 24+ hours. I made the jello mix to a T and even added a bit extra yeast when i noticed it wasn't producing after 24 hours. After adding the extra yeast, i went and sealed the lids onto the bottles in hopes that would help. No such luck, no bubbles. At that point I disconnected the bubble maker and hooked it up strait from the bottle to the tank. Still nothing. A few things i noticed though. Half the tube from the bottles to the bubble counter had water in it that never budged. The tube from the bubble counter to the tank would fill with water - never budged. I spent the last of my money on 2 check valves and a glass diffuser lastnight, but don't know if it will help at all once it gets here. I don't know what to do. I am completely stumped and frusterated beyond belief. I have put hours into trying to figure out where i went wrong.

One thing that I missed the first time around was you REALLY have to use hot water to "activate" the yeast before you put it in the bottle with the jello and sugar. It's not a convenience, it's mandatory. Otherwise the yeast never "wakes up", I think. I missed this initially and fixed it by dumping hot water (really hot) into the bottle where the yeast and jello were sitting. I figured that was easier than trying to get everything out of the bottle again.

I used abnormally hot water to where it burned my hands, if i removed some of the water from the jello mix, and added super hot and yeast again, would that work, or will i have to redo everything? The bottles have a foamey bubbly top to them and i can see grains of whatever moving slowly in the bottle.

You don't need super hot water to activate the yeast. I don't even take a temp reading anymore when I activate it. I just run the hot water until it feels hot. Using a measuring cup, add 1 tsp sugar and then 1 cup hot water. Stir to dissolve and then add 1/4 tsp yeast. Let that sit for ~ 15 minutes prior to adding to the bottle..

I have to say, this is rather odd indeed. I know some people will have issues when they first attempt it, but it usually gets going after the second attempt. So sry that this is being such a pain.

Not your fault at all, I just wish i knew what was going on. I am really hoping to get enough money together from Christmas to buy pressurized, but it kinda comes down to gettin shrimpies to make money or pressurized, so maybe I will get shrimp first then hopefully sell enough to get pressurized

Hearing that, I would say that it seems like the yeast is working - either the line is blocked (so the pressure can't get through) or the bottle is not sealed completely (so that the gas is escaping someplace else.) To me it seems like those are the only other possibilities. If the stuff inside is foaming, that has to mean (I think!) that it is producing CO2, and the CO2 has to be going somewhere....

Have you tried just squeezing the yeast bottle (to increase the pressure) and seeing if you get bubbles in the tank? Sometimes the simple solutions are best. That's how I found a leak in mine.

Ooooook think i found the problem. The one thing i didn't try was Jrman's suggestion a while back about spraying it down with 409. Found a leak in the first bottle where the tube was silliconed. No idea how it got there since it is sealed on both sides, but it was there. It has been about 30 min since i resealed it - and i really globbed it on way more then needed. Still no bubbles, but i have high hopes.
