fixture for your tank from our wide variety of aquarium lighting.
Saltwater aquarium lighting requirements are different for different types of tanks.
To keep the aquarium light on all night or not to keep the aquarium light on all night—that is the question: Whether 'tis nobler to give your fish a bit of darkness in the evenings, or risk stressing them out with a perpetually lit tank? Seriously, though, If there's one you don't want to do, it's stress out your fish. And fish do stress easily, especially if their environment has been altered drastically.
Aquarium lighting serves various purposes from spotting tank problems to regulating the eating and sleeping of your fish, but periods of darkness are necessary in order to mimic your pet's natural environment. Just imagine your fish swimming in the ocean as the sun sets and the waters gradually darken. For a number of hours per day, darkness rules and fish sleep. So, in artificial lighting, how much darkness should aquarium fish have each day?

Getting the proper amounts and types of lighting in your fish tank is vital to the health of your fish and plants. Even though your fish are in an aquarium inside your home, they still need to experience light as they would in nature so you want to be sure to provide around 12 hours of light a day. Consider using a timer so that you can consistently light the tank, inconsistent lighting may stress your fish which can lead to health problems.If you are planning on keeping plants in your fish tank, then the lighting requirements are a bit different. If you have tried to keep plants in your fish tank only to have them grow weak and die after a few weeks it is simply because you do not have the right type of light. Contrary to what many people think, aquarium plants are not hard to keep alive and should last as long as house plants with the proper lighting. If you want to keep anything other than a basic fern plant, you need a tri-phosphor tube or full spectrum fluorescent bulb which will provide the full spectrum of light that plants require.Although most aquarium setups come with hoods that have lights fitted right into them, you can also purchase different types of to suit your needs. Most beginning aquarists need only to use the lighting that is provided with the aquarium as long as it is fluorescent lighting and your tank is for fresh water fish only.If you have a saltwater tank that you plan to keep only fish in then the fluorescent lighting you would use in a fresh water tank is probably sufficient. If you want to keep live coral or rocks you will need much more light. Many people start out thinking they only want to keep fish but eventually want to expand their horizons and add and in this case it is wise to get a hood that has fixtures for 2 tubes, that way you can add more lighting as your aquarium grows. Although some corals can survive with 4 watts of light per gallon, most will need 5 - 8 watts to remain healthy and alive.
