This is a thread of interest to me since I've got a similar situation too. I've got a small 16 gallon tall tank with some wysteria, Anubias barteri, Red Crypt, Java Fern, Moss Ball, and I think Anubias congensis in it. They all should be low light plants.
(1) Do I need more light than the 15 watts for the 16 gallons I get from standard hood? I've heard that I do, even though with the high substrate in the tank I probably have more like 12-13 gallons of water. I've been able to find a 36 watt CF retrofit kit that promises to do the trick. I hear that this is unnecessary for these plants. Doing a retro will be very expensive ($75 minimum) and will supposedly greatly increase algae too.
(2) Do I really need a CO2 injector with a tank this small? It's difficult enough to cram all this into my apartment and also take time for yet another think to cram into the tank. I don't care for massive plant growth, just very gradual and more maintenance. Right now I have a small air pump with a stone just above the gravel that runs at night. I'm not sure is worth much of anything but figured it might help from what I read.
It seems you know a lot more about these kinds of plants than I or many others do and I have received conflicting advice. Thanks so much for sharing.
