by the way, this is a great thread
I do have a question though. I saw it mentioned in this thread that there are some plants that can be kept in low lighting that are traditionally considered "high light" plants due to their need for CO2 injection
Can we make a distinction between low light/no co2 and low light/co2? I know some people still do not inject CO2 into their low tech tanks, so it would be helpful to see what plants can do well without it. It might also be a nice little pushing factor to mess with diy co2 if there is a desirable plant that can live in low light with co2
I'm getting tempted to science experiment out with some diy co2 on my low tech 10 gallon now, especially since I have a high light tank that I want to make hi-tech with pressurized co2 and all.
