Would this be ok to use for my 2 gal Betta tank? If it is, is there any way to cut the bottle size and mixture measurements down so it can all work with a regular Coke bottle? I guess that using a 2 liter bottle with my 2gal would last longer, but I'm not too sure on that.
Any help?
Oh, here's the link: http://www.plantedtank.net/articles/DIY-Yeast-CO2/7/ --- I found it in another thread.
