Most basic aquariums come with lighting already installed, but you can also buy lights if you want something different. For the novice the lighting in the aquarium should be sufficient if it’s fluorescent, however, this only applies to freshwater tanks. If you will make a saltwater aquarium, better lighting is a must.
Neon lights make the fish healthy; because it most closely resembles natural light – and make the fish look better. Fortunately, incandescent bulbs with fluorescent easily replaced with another.
For aquarium fish only, use 3 watts of lighting per gallon of water in the tank. This amount of light that control algae perfectly – no more powerful and can see the green algae began to form. Do not forget to replace the lamp once every 8 months to maintain this level up to the light. For planted aquariums, different lighting needs. Unfortunately, many people make the mistake of lighting, creating beautiful water plants wither and die within a few weeks. Install tri-phosphor tube or full spectrum fluorescent light to provide the plant with the full spectrum of light they need to grow. Even if the lighting is used depends on the type of plants you have in your aquarium, a broad spectrum light bulb covers the spectrum of red, blue and green should work for most configurations.
This type of aquarium requires more light. If you start with a single fish, and then expand to add other features, the purchase of an aquarium with room for two tubes to have enough space to add more lighting as needs change. Corals require a large amount of light, from 5 to 8 watts.
