Saltwater Aquarium Lights
Whether you're cultivating a thriving reef tank or keeping it simple with a fish-only setup, it's crucial to choose the right lighting. Chewy carries an array of saltwater aquarium light solutions, including clip-on spotlights, adjustable LED systems, submersible lights, and more. You can also find replacement bulbs for fluorescent light fixtures, UV sterilizers, and hood lamps. When shopping for saltwater aquarium lights, consider the following:
- Bulb type: LED and fluorescent lights are the most popular for saltwater tanks
- Fixture: Choose from clip-on lights, strip lights, submersible lights, and external lighting systems with extendable brackets
- Size: Select a size appropriate for your tank volume and lighting requirements
- Colors: Most LED lights include white bulbs and a variety of colors
- Adjustability: Some systems enable you to change colors, adjust brightness, or schedule timers
As you're shopping for aquarium lighting, remember that it serves a practical purpose as well as an aesthetic one. In addition to helping your tank look its best, saltwater aquarium light provides energy for photosynthetic organisms to grow and enables you to simulate a natural day-night cycle to benefit your fish. If the lighting system you choose requires replacement bulbs, add them to your Chewy Autoship so you'll always have a spare ready when you need it.
Frequently Asked Questions about Saltwater Aquarium Lights
What kind of light is best for a saltwater aquarium?
What kind of light is best depends on the type of saltwater aquarium you're cultivating. Fish-only tanks have little need for light, but if you're growing coral or other photosynthetic organisms, your lighting requirements may be higher.
Should I get blue or white light for a saltwater aquarium?
A mixture of white and blue light is generally recommended for saltwater aquariums. White light is sufficient for viewing but full-spectrum lighting is essential for photosynthetic organisms. Certain corals may have a particularly high need for blue or purple wavelength light.
Is UV light good for saltwater aquariums?
While UV light can be good for improving water clarity and controlling algae growth in saltwater aquariums, it's generally not used as a primary source of light. It's usually used in the form of a UV sterilizer, which helps kill harmful microorganisms in the water column.
Why do aquariums use blue light?
Aquariums use blue light for aesthetic reasons, to enhance fish coloration and to simulate the effects of moonlight. Practically speaking, blue wavelength light is crucial for photosynthetic organisms like coral and may also promote natural spawning behavior in some species of fish.
Do you need special light for a fish-only saltwater tank?
No, you generally don't need special lighting for a fish-only saltwater tank. Standard lighting is sufficient to give you a good view of your fish and to create a pleasing aesthetic.
Do you leave the light in a saltwater tank on all day?
No, you should not leave the light in a saltwater tank on all day. Both fish and photosynthetic organisms require alternating periods of darkness and light to maintain their natural rhythms.
