For optimal coral growth, you will generally want a full spectrum of light that includes some reds, oranges, and yellows, but that is heavier towards the blue range..

White light is used over reef tanks purely for the aquarists’ benefit – not the corals’. The green, yellow, and orange components of white light do not help corals’ zooxanthellae photosynthesize.
How many hours a day do corals need light?
10 hoursIf 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.

Yes. at the surface of the water. But corals are pretty hardy and many do well in lower (and higher) lighting.
What color light grows coral best?
Fluorescent Pigments Due to its underwater environment, coral has adapted to grow best using light from the blue end of the spectrum in photosynthesis, and because of this, most fluorescent coral will glow green or red.
Do fish like blue light at night?
Nocturnal fish particularly prefer dim blue lighting at night. The blue lights not only mimic moonlight and, thus, encourage more physical activity, but these also provide them with illumination. There’s also the fact that blue light allows you, their human parent, to view them well.
How much light do SPS corals need?
The general consensus is that a PAR of 450-650 umol is good to maximize the color for most of our sps. In my own experiment this summer where I set up a tank so that it would receive direct sunlight for 4-6 hours per day, during this time the light PAR on the tank reached over 1250 umol.
Is Red Light good for corals?
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 much light do soft corals need?
Over the years hobbyists have discussed crude measurements of the amount of light corals need to thrive. Most successful reef aquarists will use about 6-8 watts of light per gallon of tank water, more in deeper tanks and less in shallower tanks.
Does red light promote algae growth?
Algae uses red light to conduct photo synthesis. 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.
Is blue light good for fish at night?
Perfectly fine in freshwater tanks, and you will be able to see your nocturnal catfish better, just don’t leave them on all night as they are one of the perfect spectrums to help algal growth.
Should I leave my fish tank light on while on vacation?
Put your lights on timers. It’s best to keep up a day/night schedule, if you don’t have a timer keep the lights off (for short trips only, longer trips need a timer). The fish will be less active, thus requiring less food and there will be less risk of having algae blooms from the extended light hours.
How long should the lights be on in a aquarium?
10 to 12 hoursHow long should I keep my aquarium lights on? To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient. Installing a timer or purchasing a unit with integrated timing can make lighting easier––just set it and forget it.
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.
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.
Is blue light better for corals?
Changes in the Color Spectrum When lighting your tank, it’s also important to note that the color spectrum you choose will affect how your corals appear. … To obtain the best color variation in your tank, many professionals recommend you use a lighting system that’s about 50 percent white light and 50 percent blue light.
Can fish sleep with blue light on?
Fish cannot sleep with blue lights on since they require entirely dark conditions for sleeping. Keeping the lights on at night will eventually impact their health, behavior, and well-being.
Why should you turn your red LED lights off at night?
Investing in a few dim, red night lights is one way to appease kids who are afraid of the dark. Leaving lights on at bedtime can lead to unsatisfying, disrupted sleep, not to mention all sorts of health risks. Keep these tips in mind to protect yourself from harmful blue light and to get better quality sleep.
Do corals need light at night?
The majority of coral growth occurs during the day as a byproduct of photosynthesis which is a means to regulate ph inside the coral tissue. Very little calcification occurs during the night. Complete darkness is not necessary, nor natural.
Do Marine tanks need blue light?
Blue LEDs and actinic fluorescent tubes, which have a very narrow output spectrum, are frequently used in reef aquariums. The blue light from these lamps causes a variety of coral pigments to fluoresce, which has an obvious impact on the appearance of the aquarium.
