    I know that this is a bit of an old thread, but I have some general C02 questions......

    Is the setup sold on bigals (or whatever the link was) too big for a 20 gallon long aquarium? I am lightly planted, but plan on going moderately planted pretty soon.

    Also, I read that it's good to have an airpump running at night only when you have plants so that you still have plent of O2 in the tank for the fishies. Is adding a C02 system going to dramatically reduce the amount of O2 in my tank at night? Should I look into a larger air pump for night time use?

    THANKS!

    You are better off making your own out of a soda bottle or a gallon juice jug. The nutrafin system.....is a bit of a ripoff imo. Plus, a 7 dollar glass diffuser will do a much better job than that bubble ladder, and won't be as much of an eyesore.

    If you have healthy, growing plants, the water will be saturated with oxygen, and that amount will hold both the plants and the fish over until the light is back on again. You can run an air pump, but you need to put it on a timer to shut off and let the CO2 build up an hour before the lights go on. It's next to impossible to asphyxiate your fish with CO2 via a DIY yeast solution, so you don't need to worry about that. Just try it out. If you see fish gasping for air at night, then turn the air pump on

    Ok.
    Gonna go ahead and give this thing a shot!

    How large of a bottle should I use?

    I have seen a lot of different numbers. It's going to be for a 20 Gallon tank.

    Also, is an airstone going to be suffiecient, or do I really need a glass diffuser?

    A large juice jug will work great.

    Glass diffusers not only work much much better, they look better too for a few bucks more. The bubbles are a tiny fraction of the size of normal airstone bubbles. You can use an airstone, but you need an additional way of chopping the bubbles up even more, like a powerhead or filter impeller. That means you have to position the airstone well, and because most airstones can blow bubbles from all sides, that gets to be hard to do as the stream of bubbles will change from time to time. I had my diffuser set up so the mini bubbles all went straight up into the intake of the HOB filter. Because I have a Aquaclear, the bubbles that don't dissolve right away get sucked and pushed upward through the sponge and filter floss, which guarantees pretty much 100% dissolve rate.

    or you can probably get one by posting from: (this is where I got mine from, 7 bucks shipped)
