Ok I need advice. I bought a light for my tank at a yard sale, only paid $3, can't beat it. It's just a regular light you normally see on freshwater 10 gallon tanks. I am planning on buying a T5 bulb if I can find one that fits and have to get a canopy to set the light on. But now I was thinking about getting a different light fixture to go on the tank because I don't think I want to have a lid on the tank. Should I stick with the light and get a canopy or get one of the fancy looking lights that kind of hover over the water and hold onto the side of the tank. Links to some good (cheaper) ones would be appreciated! Oh and the bulb that fits in the fixture that i have now is only 18", is there a T5 that will fit?
