Ok, I'm getting brave and I am going to rig up the DIY CO2. I want to have lush plants with loads of growth, instead of a few leaves every now and then. I have goldfish, so the plants are of the easy to grow or maintain variety=anubias, moneywart, ludwiga, bacopa, amazon swords, anacharis...the goldies tend to eat the plants, so I don't do any fancy varieties-just cheap (for replacement purposes), but those listed have held up well enough to grow a bit- or atleast stay ahead of the goldies snacking.
Occasionally, they go crazy, and I have to replace a few plants.
I have a 100 gallon, an 80 gallon and a 38 gallon, all with about 2+ watts of light per gallon.
I hope you guys that have done this DIY CO2 for a while, would be willing to answer some questions:
*I have a lot of empty 3 liter coke bottles on hand, can I use them instead of the 2 liter size- to save on amount of stuff under the tanks? Or are the 2 liter size just better for this purpose?
*How many 2 or 3 liter sized bottles with yeast mix would I need for each tank to produce an adequate amount of CO2? ( I was thinking 3-3 liters for the 100, 2-3 liters for the 80, and 1-3 liter for the 38)
*Lastly, what amount of sugar and yeast for the 3 liter bottle? I have only found the measurements for the 2 liter and I am not sure how much to increase the sugar/yeast.
Any help would be greatly appreciated!
