A few years ago, I took my plunge in plants with a small aquarium. I put anacharis in the back of a 14" tall tank and was pretty successful with it without CO2, extra lighting, etc. The tank had minimal lighting, a short yellow fluorescent bulb. The only problem that I had is that the leaves on the bottom fifth of the plant soon dropped off. The healthy growth in the top seem to cut off the light to the bottom. I am making a plan for a 24" tall tank and am wondering if there is some way to avoid this. I am hoping to use CO2 in this tank and appropriate lighting. Any suggestions?
