If I combine that with my current all glass aquarium hood with 1 15w fluorescent light will I be able to grow at least medium light plants on my 20g? I want to grow Hygrophila, amazon swords, crypts, possibly cabombas, and some vals.
So I would have 45 watts of fluorescent lights.

Would that be enough? and would I need c02?

EDIT: I was going to go with the 65w coralife compact fluorescent strip but I realized I would not be able to afford that for a long, long time.

2-3 watss per gallon for medium light plants i think. That looks fine

Coralife fixture is only 30 bucks more no?

In any case, that would be low-med light. The reflectors on those standard fluorescent lights kinda suck. CO2 would not be required.
