Thread: Diy C02

    Default Diy C02

    I plan on putting a DIY C02 setup on my 65g.

    I had planned to use a juice bottle and a 2 liter bottle for my reactors, and a water bottle for the third chamber. My question was with the yeast mixture.

    I was wondering if 2 cups of water, 2 cups of sugar, and a 1/4 cup of of yeast(Activated). Will this mixture work or should i add another reactor?
    Coastie-to-be... hopefully.

    When I used a DIY CO2 reactor, I used a 2 liter pop bottle which I filled 3/4 the way full with warm water, 2cups of sugar, and 1/2 teaspoon of yeast. I would add the water and suger and mix it up really well. I would add the yeast last and shake it up a little more

    Seamed to work well for me. This would last about 10 days. I had two bottles with a third overflow bottle (pic below)

    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I'd use a 1/4 tsp of yeast.

    I can keep my DIY CO2 going for a month when I mix in a multi-vitamin.

    Crush it up into a powder and shake until it all dissolves. I can never really get all of it into solution but its the thought that counts right?

    hmm I'll have to give it a try. I mixed up my first batch just now and attached the system(I already had it made). How long until i should expect to see bubbles?
