ok folks,i`ll try to keep this short.I have a 120 gal,60 inch tank,freshwater and no plants.As you may know,60 inch fixtures are hard to find so I bought a 48 inch and 2 aquarium lights at Home Depot.Seems to me both ends of the tank are a little dark.The fixture is to be housed in a hood I constructed.I guess my question is there a 48 inch I can buy that will light this up,or just give me some direction. Thanks

If the tubes are 48-inch, and two of them, you have plenty of light, especially without plants. I have this over my 5-foot 115g. It is heavily planted, and has done well for 15+ years.

Without plants, I would even consider a single 48-inch tube. The more light, the more algae, though again without plants that is not really an issue. And algae will handle a lot of nutrients. More important is the brightness on the fish. This does matter, depending upon the fish. A brightly-lit tank, and one with no "cover" as plants would provide, can be very stressful to many fish species.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
