If you plan to use this type of saltwater aquarium lighting, buy it from your fish dealer.
As you can see, the type of light you need really depends on they type of tank your running. Freshwater and fish only tanks can usually get by with the regular Fluorescent lights whereas the freshwater plant keepers and saltwater reef tank keepers will need to invest in better light sources.
Lighting a saltwater aquarium with fish and no plants coral can be accomplished using fairly inexpensive fluorescent lights. The general rule is to use 1 to 2 watts per gallon. With fish-only aquariums, the color and spectrum of the light is not as important as it is for reef aquariums. You can select the type of light that best suits your preference and shows off the colors of the fish. You should, however, use lights that are made for aquariums. Do not use standard fluorescent bulbs from the hardware store because they can promote the growth of unwanted algae in the tank.

Lighting a saltwater aquarium depends on the type of aquarium you have. If you have a fish-only aquarium, it is recommended to leave the lights on for about 8 to 10 hours a day to simulate the natural cycle of daylight. Any other time period may stress the fish and could lead to unwanted diseases. Use a timer to provide a consistent lighting cycle for your aquarium. If you have coral in your aquarium, you should leave the lights on for at least 10 hours each day. Coral contains a symbiotic algae that needs plenty of light to survive. Many people choose to divide their lights and use two separate timers. This way they can light one set and then the other to simulate sunrise and sunset. This is much less stressful for the animals in the aquarium than having the lights come on and go out all at once.Most of these issues matter more for a reef aquarium than a saltwater fish-only tank. If you do not have any photosynthetic organisms in your aquarium, either lighting works just fine. A fish-only tank only needs enough light for you to see your fish. However, whichever type of lighting you use, you should put it on a timer to give your fish 10 to 12 hours of light a day, since most saltwater aquarium fish come from the tropics and are used to this much light per day.Lighting that is suitable for fish-only saltwater as well as freshwater fish aquariums, light hoods are available in a choice of finishes, a wide range of sizes, and come equipped with standard or NO (Normal Output) fluorescent bulb or tube configurations.

This is because of a process known as osmosis. Osmosis causes water to move from low concentrations of salt to high concentrations. If a freshwater fish is exposed to saltwater, its cells will lose water and the fish will die of dehydration. There are some exceptions. Salmon, eels and some trout have adapted the ability to survive in both salt water and fresh water. There are also a few species of fish that live in what is known as brackish water, which is slightly saltier than fresh water but not quite as salty as salt water. These species can adapt over time to live in salt water. An example of these is the molly.
