not sure this is the right place but i was wondering if anyone has a reliable recipe for c02. ive used many yeast to sugar combanations and they work, but not very strong or for very long. 2 litre bottle, 3/4 full, 2 cups sugar, 1/4 tsp yeast,1 tsp baking soda blah blah blah. Ive used less sugar more sugar, less yeast more yeast, warm water cold water, activated yeast beforehand to supposedly prevent mass die offs? brown sugar, molasses,..... the list goes on and on. is it because im using tap water? my water is very hard and ive heard from some sources that this has an impact. im at a loss. planning on getting a 5 lb pressurized setup, but its gonna be a while yet so my two diy reactors are gonna have to do for a while. any experts out there that can explain a good recipe to me as though im dumb monkey? i would be very thankfull

Have you tried different yeast ? Not different amounts, different yeast all together. IME, that stuff becomes less active the longer it sits around the house.
In the past when I had trouble getting the mixture to work, going to the store and trying some different yeast usally worked like a charmIf you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

thanks for the quick reply cliff. yes ive got 3 different kinds in the fridge as of now. the packets of ultra active yeast i bought recently give strong results for a day or so and then it dies off fast. the regular bakers yeast lasts a week or so but even with 2 reactors going, im barely getting a bubble per second. my 29 gallon has a drop checker in it and it reads insufficient all the time. cant wait to get a pressurized system!!!

First off, I get better results with live yeast from the store that is refrigerated. Next, have you tried using less sugar to start, and every other day, add some more (to equal the remaining same total but added over a week?) This should make it more even.Knowledge is fun(damental)
