This will be a freshwater setup. I'm not planning on planting it at first--perhaps in the future. Initial setup will be eight 32W or 40W T-8 tubes at 6800K and 10000K. I've considered other colors, but really like the bright blue-white the higher temps give.
Any more details on this cross-bar frame idea?
You're right, my bad. 2' wide tank, 2' wide fixture
. My initial thoughts were if you angle them up like a gable/peak, the light is going into the room more than into the tank.
Do you already have the fixtures?
Maybe 2, 36" fixtures would be something to consider? Evenly spaced on a horizontal plane, I don't think you'd have any dark areas in the tank. You could mix the bulbs too, 10kK, 6700K, Actinic since you have 8 bulbs. Yep, the 10kK/blue does look good (love it on my BW
Here's a great fixture with those dimensions: 3Ft/4Bulbs fixture
Crossbar, like a roof rack on a car is what I was thinking. Kinda like this: ROOF RACKS CROSSBARS CROSS BAR CAR CUV SUV WINDOW FRAME | eBay
Or build a hood like you see on many large tanks and hide the fixtures all together.
