Request Co2 (reactor) preparations in detail

Yep, I made a video for those of you that want to know the details of my current setup and sugar yeast mixture.
All the information you need is in the video, but once again:
200 grams sugar of which 2/3 is brown and 1/3 is white sugar.
Add HOT water to melt the sugar (half a bottle) and then add 1 teaspoon of yeast, add cold water (1/4 bottle) and shake well.
This should keep your Co2 going for about 2-3 weeks.
Turn on your airpump at night, DO NOT FORGET THAT or else you will kill your fish.
If you dont trust yourself, maybe just open the lid on the main bottle and let the Co2 escape, leave the cap loose and turn it back on in the morning.
The more yeast you add, the more Co2 will be produced, the more foam will build up in the bottle and the faster the sugar will be used up.
Give it a try, it does help ;)
What yeast to use? Just normal baking/bread yeast.
Add baking soda to increase the Co2 production and slow it down a little.

Good luck :)

ok iv been looking for "plain bankers yeast" i dont know what to look for... every time i look for yeast i get "active dry" or "quick rising" yeast and i NEVER see any yeast that is labled "bakers yeast' could you please tell me to BRAND NAME or the same exsact yeast you use... because i cant seem to find the correct yeast.

@killerlief The quick rising yeast is what you DON'T want, but the active dry is exactly what you need. Make sure you update the mixture of yeast sugar and baking soda. 1 cup of brown sugar, half a cup white, 1 teaspoon yeast and 1 tsp baking soda.

This should give you the best result, if not, just try some slight variations.

Take care :)

guys plz help me with this stupid quest ... how can i get rid of the alcohol & got only co2

[oBseSsIoNPC]

@3waad3 I apologize for the late response, I bet you have the answer for your question already. You can't get rid of the alcohol during the process. The bacteria produce it as result of digesting the sugar. But when the mix is done producing Co2, you can just dump the useless solution in the sink. Other than that, there are Co2 cartridges you can buy also. Pure compressed Co2 released by a contraption.

hey man, im going to use this in my 3 gallon tank with my shrimp. because of the smaller volume of water i wont need as much co2. do you think i can use the same recipe, and same size bottle as you, but only put in half a teaspoon of yeast? i hope this will make it last twice as long but still produce a steady flow of CO2

[oBseSsIoNPC]

@bigun1999999 Sure thing man, give it a try. Try and error is the whole concept of these DIY contraptions. Let me know how you make out. Remember, the sugar makes the biggest difference. And make sure you don't use quick rise yeast, only regular. Good luck friend.

how do you store yeast that you buy (since its not all used up at once) ? i put it in the freezer, and everytime i need to use some i take out a bit keep it outside for about half an hour then use the yeast. But when i put it in water there is no frothing....why?

[bluedisk0123]

i would not recomend leting the c02 get into your cannister sometimes it will get trapped and cause pressure on the seals and cause it to leak.
