There should also be some online articles for
easy-care plants. I have those and don't do
any CO2 injection. One tank has only gravel
as a substrate. Plants do fine. Java Fern,
various Crypts, maybe a sword or two (I still
can't ID some plants!). Lighting is what came
with the hoods (flourescent), nothing extra.
I only use fertilizer in the tank that has a gravel
substrate and only about once a month; the other
tanks have Profile under gravel and get their
fertilizer from the fish. I have baby plants all
over the place.
