Fish Tank & Aquarium Lights

Whether a fish is living in salt or freshwater, aquarium lighting is always a necessity for any tank. Lighting is not only ideal for the pleasure of those viewing your aquarium, but it also gives off vital energy and influences fish behavior and other living things, like coral. Fish tank LED lights are a game changer from the standard fluorescent lights. This light takes very little energy to produce, and has a low heat output. LED lights have different color spectrums that provide various enhancements and effects. For this reason, it's important to know about each one. Freshwater fish tank LED lights come in a variety of colors, like white, royal blue or magenta. They can be one tone or combined for bonus effects. The less intense white LED aquarium lighting enhances red, yellow and orange tones and is excellent for strong growth in your tank, as well as supporting photosynthesis. The more powerful white light complements silver, blue, black and green colors and is a good choice for tanks with a large quantity of fish. This tone can be combined with blue or magenta aquarium lighting. If you combined this with blue LED aquarium lighting, it will give off a deepwater appearance and will provide added shimmer to blue, green and red tones. If you're interested in something for your freshwater tank that has a lot of plants and fish, the combination of white and magenta could be the best choice for you. This will encourage plant growth and help them reach their color peak. This combination will enrich green, red, yellow, blue and orange colors. The royal blue fish tank LED lights used alone are the perfect choice for fluorescent fish and will definitely give them a pop of color. The magenta aquarium lighting, which can be used by itself or combined with white and blue aquarium lighting, is ideal for planted aquariums and boosts red, green, blue and pink aquarium inhabitants. Saltwater fish tank LED lights have the same tones available, but also have an LED aquarium lighting combination that gives you the opportunity to fit your aquarium's color necessities perfectly. The less intense white LED aquarium lighting enriches blue, red, orange and green tones and is great for coral and macro-algae growth. The more powerful white light enhances blue, purple, pink and magenta colors. The royal blue light by itself is great for deep tanks and heightens blue, green, orange and pink fluorescent colors. You can combine white and blue LED aquarium lighting to boost coral growth. There's also blue and magenta, which is a great mix to keep your coral vibrant and colorful, enhancing blue, purple, orange, yellow and green colors. The most popular mix for saltwater is the LED combination that enriches all colors and is great for any tank. For example, the Aquatic Life Edge Aquarium LED Light has settings to replicate underwater sunlight and moonlight. If programming your aquarium lighting from the comfort of your own couch sounds pleasing, the Current USA Orbit Marine Aquarium LED Light gives the same effect but with a cordless remote. This LED aquarium lighting system also includes weather effects like cloud cover and lightning storms.

Frequently Asked Questions about Fish Tank & Aquarium Lights

How long should aquarium lights be left on?

Aquarium lights should be left on for between 8 and 12 hours a day. Planted aquariums with live plants need more light, and these should get 10 to 12 hours of light a day. Tanks without live plants do better with slightly less light, or roughly 8 hours a day, as too much light can promote algae growth. You can get aquarium lights with an integrated timer or plug them into a programmable light strip that is timed.

What are the different kinds of aquarium lights?

The different kinds of aquarium lights include standard fluorescent lights, compact fluorescent lighting, high intensity metal halide lighting and LED fish tank lights. You can also find specialty T-5 HO (High Output) bulbs for planted aquariums and VHO (Very High Output) bulbs that produce high-intensity light. Choose from aquarium hood lights, top-mounted aquarium light fixtures, aquarium lights with nightlight features and more. The best kinds of lights for most aquariums are usually long-lasting LED lights or low-heat fluorescent aquarium lighting fixtures.

Do aquariums need special lights?

Aquariums do need special lights, both to enhance their aesthetic beauty and to help the fish and plants inside thrive. There are many types of fish tank lights for different fish habitats and specific lighting needs. You should choose a light that is not too bright, to avoid disturbing your fish and promoting algae growth, and pick one that doesn't give off too much heat. If you have live plants in your aquarium, be sure to choose a light that is appropriate for their needs.

How do I choose the aquarium lights for my fish tanks?

Choose the aquarium lights for your fish tanks based on what is living inside them. While fish need some light, their light needs are not as intensive as those of live plants, so consider the needs of your aquarium plants first. If you have an unplanted tank, try to get lighting that most closely emulates the natural environment of your fish. Different species of fish are used to different amounts of light, so check lighting recommendations for the type of fish you have.
