Anemoneman and Bob thanks for your input.
I had thought about MH
's for the tank since it is 72" long and has two top braces it is already split up into 3 2' rectangles.
One of the reasons I decided to go with the 4X96W PC
's is because of the tanks width. This is a long and narrow tank.
The tanks measurements are far from standard off the shelf. I know its an all glass tank as I still have the orgional bubble sticker from the tank but it measures 72"Long X 20" High X 13" Wide
The tank is bascily a narrow 125 since a 125 measures 72" Long X 22" High X 18" Wide
In looking at the all glass prodcut line a standard 75 Gal
tank is 48" Long X 20" High X 18" Wide so its got an extra 5" of width vs my tank.
light is great when your needing to light an area that is approx 2 sqft but when your acutally lighting a tank that is more like 2" long x 1" wide I felt I would end up lighting more of the outside of the tank than I wanted.
I must say I have seen tanks with MH
lights on them first person and LOVE the way they look.
