Freshwater Fish Tank Lighting
If you have a standard freshwater aquarium, you should replace the fluorescent light bulbs once per year or when they burn out; whichever happens first. When the light bulb becomes older, the color spectrum begins to shift. Although it is not apparent to the eye because the changes are so subtle, it will cause algae to grow in your aquarium. Another tip is if your light fixture is not working anymore, it might actually be a bad starter. This can be replaced in less than a minute and does not cost very much. Where as a new light can cost $20 to $50 depending on where you buy it. You can also reduce algae growth by having proper filtration and running your lights on a timer.
