Hi,
I am forced to keep my new project small so I am setting up a 10 to 20 gallon planted tank. Most of my research leads me to costly answers for large aquariums. I was wondering what would be a good system for CO2 injection for a small tank. I would also take suggestions on anything else from substrate to filtration to plant species.
