Low, LOW light options - Thanks
 

Thanks for the advice so far. Please feel free to keep advice coming. (
btw, I updated my name from t to Todd, sorry if there was confusion).

Thanks for the species recommendation. I've already setup the aquarium and
have fish in it. My hood I built has 120 watts of light (4 30w full spectrum
bulbs). However, with the tank being about 21" deep, I think it needs a bit
more light. I appreciate the advice about making the effort of putting in
the proper amount of light for plant production. I am endeavoring to upgrade
the lighting in my hood, and I appreciate the advice on species that will
allow me to at least get started.

Warmest thanks,
Todd
