saltwater aquariums
are lit using primarily a mixture of white and
blue colored light
, at least that is how it appears to our eyeballs. While some hobbyists prefer a whiter look and some prefer a bluer look, the reason we use this color of light is important.
What lights do I need for my reef tank?
As a basic rule to determine how much light your tank needs, you should consider that most reef tanks require an average of 4 to 6 watts per gallon of light for
low-light corals
and as much as 10 to 12 watts per gallon for corals that require more light.
Do saltwater aquariums need blue light?
What about white light, do corals need them to grow in a reef tank? Corals don’t need a white light to grow in your reef tank. Instead, they need blue light to grow healthily White light is more useful to humans, as it helps them ‘see’ the corals in the reef tank better.
Does a saltwater aquarium need a light?
Coral reef aquariums require a lot of light This is because the coral contains a symbiotic algae called zooxanthellae that uses light to make food for the coral.
Do corals prefer blue or white light?
Efficient photosynthesis requires not only adequate light intensity but also the correct spectrum of light. Terrestrial plants, like those found in our garden, favor colors in the yellow, orange, and red range while corals favor colors in the blue spectrum.
What is the blue light for in a saltwater aquarium?
coral growth
A specific range of the blue light spectrum is directly responsible for coral growth. Our research into the photobiology of corals shows that a specific wavelength within the blue light spectrum significantly stimulates the creation of new calcification centers in the corals’ skeleton.
Do corals need red and green light?
So basically when it comes down to it your coral will thrive under any of these: Red light, white light, green light, blue light, UV light.. or any combination.
Do corals need blue light at night?
Blue light is the light that regulates circadian rhythms (day-night-rhythms), mainly through the cytochromes, receptor pigments of nearly all life forms, from bacteria and yeasts to humans. When blue light is on the signal is that there is no dark period which can disturb corals severely and will not make fish lucky.
Does Bluelight stress fish?
No, you should not keep a blue light or any other colored light on in your fish tank through the night. Unless you have nocturnal fish, they depend on light cycles to maintain their sleep cycle. Leaving a light on at night will disturb this cycle and result in sleep-deprived and stressed fish.
Does blue light grow algae in saltwater?
blue leds
are supposedly not meant to cause algae growth.
Can I turn my saltwater tank light off at night?
You can shut off your aquarium’s lights anytime you want, so long as they’re consistently on for about 12 hours and off for the same length of time Most aquarists prefer shutting them off at night because they would rather see the tank lit up during the day.
How many hours should a saltwater tank light be on?
Essentially, the ideal time to have your lights on full is between 9 and 12 hours Providing ramp up and ramp down time if possible. This gives the coral enough time (roughly 9 hours) to grow and reward from the photosynthesis.
What kind of lighting do clownfish need?
Tang, Angel, and Wrasse Nerd! No, clownfish don’t need lighting , necessarily. If they can see to eat you’ll be fine. You won’t enjoy them as much without bright color (light) and any coral/anemones will require light.
What LED light for coral?
Blue Plus OR3 LED Light Bar The OR3 Blue Plus bars utilize specially selected LEDs concentrated in the blue light spectrum to produce truly fluorescent coral colors.
How many watts of LED lighting do I need for a reef tank?
A good basic rule to follow is to provide 1 to 2 watts of lighting per gallon for fish-only aquariums, 2 to 5 watts per gallon for freshwater planted aquariums, and 4 to 8 watts per gallon for reef aquariums.
Can you grow coral with LED lighting?
Yes, LEDs do grow coral – just ask our experts at LiveAquaria.com! They have been using LED lighting for quite some time now over our coral tanks with amazing results. The specific spectrums provided by LED lighting can bring out colors in certain fish like you’ve never seen before.
How many hours a day do corals need light?
For saltwater reef tanks containing corals, lights should be on for 9-12 hours every day. Corals need light to produce food. An algae in their tissue called Zooxanthellae processes light into energy and without enough light, the coral would die. Fish do not require light to survive.
Do corals need light at night?
Even the optimal amount of daily photosynthetic activity generates residual energy inside the coral that must be released, so they need a period of darkness, just as much as they need the light Our research has shown that to get optimal coral growth and coloration, light and dark periods should be about the same.
Do ZOAS need white light?
Any light can grow zoas.
What color light is best for fish?
Tropical, or Colour-Lite bulbs , are designed for fish viewing. These accent red and blue hues, and are ideal for making your fish stand out better. They will give a much brighter visual, and mean that you see your fish more clearly and get the best out of them.
Do blue aquarium lights cause algae?
Contrary to what you may have been told, LED lights do not cause algae growth any more than other aquarium lighting options Some LED lights also have adjustable light options to dim or brighten the light according to your fish’s needs.
Is Moonlight good for reef tank?
Benefits of Moonlight for Reef Tanks They provide comfort to diurnal species that might become scared in total darkness When timed to simulate the natural lunar cycle, they help to regulate aquarium animals’ biological clocks.
What color light is best for coral growth?
LED spectrum chlorophyll A and B for growing corals Wavelengths below 400 nanometers are considered UV or ultra violet Above 700 nanometers light is considered infrared. The color spectrum is very important for coral growth in your aquarium because certain wavelengths are more beneficial to coral than others.
How do you tell if my corals are getting enough light?
Well-Known Member. Keep a look out for a coral color being pale vs bleached as well. A coral that goes pale very quickly after making a lighting adjustment is normally from to much light A coral that does it slowly can be from to little light, to high or low a temp or to low nutrients.
What Colour light stops algae growth?
Our results show that algae grows the best under white light and more in blue light than red light Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth.
What does green light in fish tank do?
An excess of green light within your aquarium is one of the most common causes of nuisance algae development, and can quickly lead to a murky, visually unappealing tank.
What does red light in fish tank do?
Algae uses red light to conduct photosynthesis This scientific fact can be used to limit algae growth. Using only a little red light will slow algae growth. The less you use, the slower algae can grow.
What makes corals grow faster?
Modest lights then with high water flow and heavy feeding will grow corals amazingly fast. Adding brighter lights or leaving your lights on longer will do comparatively less (near nothing) for growth.
What spectrum is best for reef tank?
AquaBlue Plus (AB+) is the go to spectrum for reef aquariums. Emitting the optimal wavelengths and intensity for strong coral growth and color, it’s a proven color spectrum for successfully keeping live corals.
How often should you change water in a reef tank?
As a general guideline, a monthly 25% water change is recommended. However, smaller, more frequent water changes (15-20% every 1-2 weeks) are preferable for heavily stocked aquariums or aquariums with large fish.
Do corals use red light?
It’s important to remember that algae loves red light so definitely don’t overdo it, and many of our deeper water corals like Leptoseris and Stylocoeniella, and many chalice corals will not appreciate too much red light for too long.
How high should light be above reef tank?
Do your best to completely darken the room where the aquarium is located, except for the aquarium lighting. Raise the light well above the aquarium, perhaps as much as 24 inches Pay attention to the “edge” of the light on the floor. It should be fairly obvious with most lights, due to reflector or optic performance.
Do fish like color changing lights?
Another option is the color-enhancing bulb. These are generally warmer lights, which means that they give off an orangish-yellow hue which makes the aquarium environment appear warmer and more pleasant. They work well for aquariums with freshwater and saltwater fish, but not for aquariums that have live plants.
Do LED lights hurt fish eyes?
How Lighting Affects Fish. Fish are not as reliant on light as plants. In general, aquarium owners can use incandescent, fluorescent, or LED lights for fish but should be aware of the heat issues that incandescent lights cause.
Can fish sleep with black light?
Black lights should not be used to heat or illuminate a fish tank Fish need aquarium lighting that’s designed to provide the natural lighting they would receive in the wild. Because black lights are ultraviolet, it’s only safe to use them in small doses.
