Hi! First post here. I saw this website and figured it could be really useful for setting up my tank.
I have an old bowfront 40g I really want to turn into a planted tank.
I have a t8 fixture(i think? The old bulbs in there are about between the size of a quarter and a nickel), and I would like to go for medium lighting.
Heres my fixture:
(sorry about the dustiness of it, i need ot wipe it off)
Each bulb is about 18 inches. http://www.drsfostersmith.com/produc...fm?pcatid=4489
I was thinking about getting two of these. Would this work? How many watts per gallon would that be, do you think?
