I did a search for this topic and it seems that I cannot find enough specifics to help me decide on lighting.
So after several long months of setting up my 240gal freshwater tank (I will spare the details for now) I am ready to square away my lighting.
I have tried all sorts of lighting on several different tanks over the years and found that my requirements aren't that big.
For the plants that I am using, the intensity does not need to be that strong based on past experience. I am using dwarf and giant hairgrass, tropical java fern, 4 types of Crypts, Bolbitus and Anubias.
The tank dimensions are 2'x2'x8'.
Metal Halides are not desired due to heat and size. I think T12, T8 or CF will due fine. I don't even think the CF is necessary with the plant pallet I am using.
T8 has given me great results with high internsity needing plants. The plants that I am using do not require serious lighting, so T12 could be the ticket.
I am leaning towards T12 because I think there are more "colors" to be found with this type of bulb. T8's tend to be too yellow. I like the ominous white, pink or blue that T12's can deliver.
The real question is, will T12's suffice for a 2' deep tank? I think 3 watts/gal would be sufficient, but that doesn't play too well when the tank is this deep.
Any suggestions, recommendations or past experience out there?
I need to get on this part of the project!
