aquatica Posted March 1, 2009 Report Share Posted March 1, 2009 How long does it take for CO2 to come out of a DIY co2. Usually it is almost immediately, but one must keep in mind the type of diffuser you use may need more pressure than you are producing. What type of DIY unit have you made? and what type of diffuser are you using airstone etc.? Rudy Quote Link to comment Share on other sites More sharing options...
Blue Ram Posted March 1, 2009 Report Share Posted March 1, 2009 Check and make sure your yeast is still active as it does expire. It is best to keep it in the fridge. Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted March 1, 2009 Report Share Posted March 1, 2009 Mine usually takes a couple hours to start producing enough that bubbles are coming out on a regular basis. The temp of the room will also affect how fast your DIY produces. In the winter, as my tank is in the basement, my DIY was barely producing anything. The mix was too cold. I now put the bottle on top of my lights so they keep the mix nice and warm. Quote Link to comment Share on other sites More sharing options...
catshanon Posted March 1, 2009 Report Share Posted March 1, 2009 Check out the bottom link (if you haven't done so already..), very good explanation of the reactions going on for producing CO2. Treatise on DIY CO2 When I was doing DIY, it took quite some time ( > an hour) for the bubbles to come out of the powerhead..I also found that the airline tubing got clogged with yeast mixture over time...(but maybe that was because I was squeezing the bottle to get the gas into the tank..)

Tarolisol Posted March 1, 2009 Author Report Share Posted March 1, 2009 I did it based off that website, Im thinking my yeast has gone bad because its been lalmost 24hrs and nothing. Its 3 pop bottles and the diffuser is a little power head. Quote Link to comment Share on other sites More sharing options...
werner Posted March 1, 2009 Report Share Posted March 1, 2009 There's always the possibility that there's a leak... Quote Link to comment Share on other sites More sharing options...

If the yeast is alive, in about 15mins it should be all foamy and bubbly. Quote Link to comment Share on other sites More sharing options...
Tarolisol Posted March 2, 2009 Author Report Share Posted March 2, 2009 Ill check my yeast, I dont think there would be a leak, if you check out my 90g tank journal theres a picture of it. Its all push fittings and bulk heads. Quote Link to comment Share on other sites More sharing options...
Baos Posted March 2, 2009 Report Share Posted March 2, 2009 Maybe you have some bad yeast? I use about 1/2 cup sugar, 2 cups ro water, and 1 teaspoon yeast. It goes hard at about a bubble a second for about 3 days. Quote Link to comment Share on other sites More sharing options...
catshanon Posted March 2, 2009 Report Share Posted March 2, 2009 Ill check my yeast, I dont think there would be a leak, if you check out my 90g tank journal theres a picture of it. Its all push fittings and bulk heads. I saw your picture of the DIY in your 90G journal. There are a lot of junctions, so more chances of leaks. Check this out, and see if you can do this. I did the connection by drilling a hole and didnot use any bulkheads and silicone and I was getting CO2 within an hour.. Connection without bulkheads and silicone Quote Link to comment Share on other sites More sharing options...
Tarolisol Posted March 2, 2009 Author Report Share Posted March 2, 2009 Its water tight, push fittings are typically pretty good for that. Im pretty sure its my yeast. Sucks I wasted all that sugar. Quote Link to comment Share on other sites More sharing options...
byte Posted March 3, 2009 Report Share Posted March 3, 2009 (edited) Are you using a check valve in the tubing? Make sure it is installed the correct way Hot water will kill yeast, recommended temperature is 100-110 (40 C). How do I proof yeast to test for activity? To proof yeast, add 1 teaspoon sugar to 1/4 cup warm water (100° to 110°F). Stir in 1 envelope yeast (2 1/4 teaspoons); let stand 10 minutes. If the yeast foams to the 1/2 cup mark, it is active and you may use it in your recipe. Ideal temperature ranges are 100°F-110°F, when yeast is dissolved directly in water; 120°F-130°F when undissolved yeast is added to dry ingredients.

Erin Posted March 7, 2009 Report Share Posted March 7, 2009 I'd also suggest to the leaking. I had the same problem. Just head down to a home depo or such and grab a tube of silicon and put it at around the tubing ie tops of the pop bottles inside and out. I'd first take one out and put it in a bunch of water. if it leave you'll see it bubble there (place the whole bottle under the water). for me the silicon work wonderful.
