Diy Co2

Hey everyone, question: I was talking with some of you last week about maybe switching over to a pressurized CO2 system. Well, research has indicated that my money situation is not up to that at this time. But I had another idea. All us DIYers use those 2 liter bottles for our CO2 generators. Has anyone ever used the 3 liter bottles instead? I've been thinking about it and if I use two of the 3 liters, I get a total of 6 instead of my current 4. (duh.....thanks for the math update Jake).

Is there any reason this won't work? I certainly can't think of any chemical reason. Input?

It will work. Regardless of whether it is a 20 oz bottle or a 5 gallon bucket. Keep the approximate recipe ratios the same for what has been working best for you. It won't last any longer, but it will generate more CO2 in operation. Good luck!

If you can use any size container then why do you always read that DIY is insufficient for larger tanks? Is it just the inconvience of changing the yeast mix in a large container vs. a tank of CO2? Or some other reason?

It's because production is not steady...and in a big tank, you need a lot of CO2 all the time. I just switched from DIY for my 20 gallon to pressurized. Hooked up my solenoid and needle valve and Clippard tubing (Thanks Rex!) last night. I'll never go back to DIY. It's just a recipe for disaster if you have high light/EI.

Having said that, I am using a 4 L juice jug to do DIY CO2 to my low light 125 gallong SA biotope and it's working ok.
