I just wanted to share my light modification: Back in January when I bought my tank, stand and equipment from a LFS I was sold a two bulb 28w 48" T5 Coralife light fixture (I didn't know any better at the time). I added a LED fixture to the aquarium in May but wanted to either buy a T5HO or modify this one. I chose to modify the fixture since it would be under $25 plus the cost of new bulbs. If anyone has seen these fixtures, they are about the width of 3 bulbs and about 3/4" high. The smallest T5HO 54W two fixture ballast I could find is 1" x 1.3" x 9.5". When I pulled it all apart I found the original ballast is just a circuit board wrapped in plastic. The channel of the fixture that fits the wires, ballast and switch is about 3/4" square so the new ballast obviously would not fit. So, being that my canopy is floating and you cannot see the light fixtures anyway, I just attached the ballast to the top of the fixture and ran the wires in through the side and kept everything else original.
