All aquariums require lighting. It not only enhances the look of your aquarium, including the dcor and the fish themselves, but it is also necessary for the ecosystem in your tank, especially if you have live plants.
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 aquarium lights is measured in watts; usually, aquarium lighting should be about 2-3 watts per gallon of water in the tank. Planted tanks will require more lighting than the exact same aquarium with plastic plants. More lighting is not always better. Some fish enjoy a very bright lit home, but most like a more subdued environment. Lights that are too intense will stress your fish, and can cause algae growth.
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.
If you have live plants, you'll need an aquarium fluorescent light. Available in the form of tubes or compact fluorescent bulbs, their light is much brighter and does not give off any heat. The fluorescent light can be used by your live plants. If your tank is very heavily planted, you may need more than 3 watts per gallon. A compact fluorescent bulb will fit into any fixture designed for incandescent bulbs, while fluorescent light tubes need to be purchased at the correct length for your aquarium hood.
Some fluorescent lights come in specialized spectrums, though you can use an ordinary household fluorescent light. "Full Spectrum," which contains all of the necessary wavelengths of light, is the best choice for brightly colored fish and healthy plants. Different parts of the spectrum have different effects on your aquarium. Purple-tinted lights will bring out the colors in bright tropical fish; the blue area of the spectrum increases algae growth. Orange-red light is ideal for your aquatic plants.
Although a lot of fish are nocturnal, it is still important for the main aquarium light to be turned off at night to imitate the natural order they are used to. The use of submersible LED lights will allow you to watch your fish when the main aquarium lights are off. You can use different colors to highlight the dcor or the fish. To watch the fish without disturbing their daily routines, use small red or blue LED lights.
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.
