jstehman Sounds like a small leak.

If you get a rush of bubbles when you shake the fermenter, you don't have blockage.

Put some kiddie bubble solution on the lids where your airline goes and you will know for sure.

jhays79 Buy a 20 dollar powerhead and run your co2 into thfe intake and let the impellar chop it up and shoot the bubbles across your tank.

plantedtankfan i am using a bell type diy diffuser with a fine airstone on the tubbing from the reactors. I just set this whole system up sunday so it is very new. i think my reactors is producing some co2 but it does get into my tank. It has been over 24 hours now. Today, i shake the bottle and a rush of co2 bubled in to my bell reactor. but then it stop.

puopg I had the same issues as you before. Heres what i do:

I use sugar, Yeast (like fleishmanns or something just basic yeast you can find in grocery stores) and water. for equipment i used a 2 liter bottle and another smaller bottle filled with only water. In teh 2liter bottle i dissolve about 2 cups of sugar into it. Yeast i use probably like 1/2->1 tsp yeast. Proof it for 20 minutes but mixing it with lukewarm water. u should see stuff happening. Then mix the two solutions. I leave some space between the water level and the top of the 2L bottle so you dont get crap flowing into the other bottle. From the 2L bottle, take a tube and route it into the smaller bottle filled with water. That simple acts as a water filter so the CO2 from the 2L bubbles through the water and up. Then from the small bottle, taht rube coming out goes to the diffuser. It will take about a day for you to see good CO2 production. I highly doubt you will ever produce enough co2 this method to gas your fish so don't really need to worry about too high levels. Im sure its possible, but very unlikely.

If you can find it, i mix my yeast with some wine yeast as well. Wine yeast can take higher alcohol levels but produces co2 at a lower rate. However, its very consistent. I tried all wine yeast before. It sucks. Almost no CO2 came out and it takes like 2 days to get going. However, I mixed the two and it wasnt that bad. Also wine yeast settles to the bottom whereas bakers yeast floats. When you change out the yeast solutions, leave some of the Original liquid in as it can help speed up fermentation process IME.

What diffuser are you using? The diffuser might be clogged if it still cant get out.

AnotherHobby How long has it been? Depending on the diffuser and the temperature (cooler temps will slow it down), I've had it take up to 24 hours to get going.

plantedtankfan I just made my second batch of co2. It is not producing any co2 into my diffuser and my tank. But when I shake the bottle, a little bit came out and in to the tank. I checked for leaks already, none was found. I did 2 cups of sugar, 1/2 tsp of yeast and a dash of old baking soda. I mixed the sugar and baking soda with warm water and activated my yeast with some warm water and sugar. then i dump the mixture together and sake and then hook it up to my tubbing.Does the temperature effect the rate of fermentation of the yeast? or what am i doing wrong?

I assume you mean separator and not diffuser. I'd fill the separator maybe 3" from the top. You need a little room for potential over flow from the reactor, and you obviously need an air pocket at the top or fluid will get pushed up your airline.

Also, not all DIY's show this, but you'll want a check valve between the reactor and the separator, and as close to your reactor as possible so you can disconnect it for a swap out without depressurizing and loosing the CO2 that's in your separator.

So the airline tubing from the CO2 canister will go under water and the other airline tubing will be above water right?

plantedtankfan Should I add water to my DIY CO2 separator? I saw some with water and some without water. I am confused. Help...

bennyjam No problem. Glad it was helpful. :-)

funkman262 That's good. And thanks for posting that link. I skimmed through it because I felt like a dummy forgetting about all of that and I realized that I completely forgot about the sugar in my earlier post lol. That write-up is pretty much as good as it gets. There's absolutely nothing that I could add.
