Choosing the Correct Lighting for Your Aquarium

By Leonard Boyler

Lighting is always a requirement for aquariums. Not only does it highlight the fish and the dcor but it also serves the ecosystem in the tank, particularly if you have decided to add fresh plants to your tank.

When buying an aquarium, getting a full tank setup means getting all the necessary equipment, and that includes the lighting. However, if you prefer to have a more customized setup, purchase separate lighting instead. The light you have to get will depend on the size of the tank and your selection of fish and plants.

The power of the aquarium lighting should be around 2 to 3 watts for every gallon of water in the tank. Keep in mind, however, that the lighting requirements for the aquarium with live plants would be more than that of the same aquarium with artificial plants. Be careful though, because more light is not always good for all fish. Some fish thrive in a brightly lit habitat, while some are bothered by too much light and end up being stressed. Furthermore, an environment with too much light causes algae to grow much faster.

For your lighting needs, you can choose between using fluorescent or incandescent bulbs. Incandescent bulbs are inexpensive, and therefore good for smaller aquariums, but their yellowish glow is not quite the same as natural light. They also generate heat so it would be a good idea to keep a thermometer handy, and monitor the water temperature regularly.

Fluorescent light is much more appropriate for an aquarium with live plants. They come in tubes or compact bulbs. The light they emit is more natural looking and does not produce any significant heat. If you have more fresh plants in your tank, you might need more than 3 watts per gallon of water. When purchasing a fluorescent tube, be sure that the length will fit into your aquarium hood. A compact fluorescent bulb, on the other hand, is equipped to fit into any plug designed for incandescent bulbs.

You also need to know about light spectrum. Fluorescent lights have specialized spectrums for your aquarium needs. Full spectrums gives out all the required wavelengths of light that is best for your fish and fresh plants. Different parts of the spectrum have distinctive effects on the different contents of your aquarium. Tropical fish grow brighter with purple-tinted lights. Aquatic plants grow better under the orange-red light.

Your aquarium lights should be turned off at night, either manually or using a timer. Many fish are nocturnal, but even those that aren't need a night. If you want to watch your fish when the main lights are off, use submersible LED lights, which come in a range of colors to accent your fish or dcor. Small red or blue lights will allow you to watch the fish without disrupting their daily patterns.

Aquarium bulb replacement is an important and unavoidable part of the maintenance of your aquarium. The bulbs should be replaced yearly even if they are still working because they gradually dim with time.

Aquarium lighting, well-chosen, will have a big impact on how your aquarium looks and on the well-being of the life in it, so it deserves your careful consideration. - 29953
