What is actinic radiation?
Electromagnetic radiation that is capable of initiating a chemical reaction.
The term is used especially of ultraviolet radiation and also to denote radiation that will affect a photographic emulsion.
From: actinic radiation in A Dictionary of Chemistry ».
What is actinic blue light?
Actinic Bulbs – Emit light predominantly from the blue end of the color spectrum. Recreates light conditions found in deep water and provides the light energy necessary for proper photosynthetic coral growth. Actinic bulbs are ideal for reef aquariums. Plant Bulbs – Emit light that stimulates plant growth.
What does a blue light do in an aquarium?
This is particularly good for nocturnal fish, as a dim blue light can be left on the tank to simulate moonlight and allow for feeding and viewing purposes. There are even LED lighting strips that replicate the monthly lunar cycle. You can have fun changing the light with the remote or app.
Do LED lights cause algae?
LED aquarium lights are not any more likely to cause algae growth than fluorescent bulbs, with some hobbyists even convinced that an LED bulb will actually discourage algae growth. … The general ‘algae’ rule is if the intensity is too high, algae will soon start creeping from the edges of your fish tank.
Are LED lights harmful to fish?
Yes LED lights are okay for fish. LED lights are also okay for live plants in freshwater aquariums. Aquarium lighting should be turned on for approximately 8 to 12 hours per day.
How many hours light do corals need?
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.
What is actinic lighting for aquarium?
Actinic is a term used to describe lighting which produces high levels of light in the blue wavelengths. This type of light is important in aquarium use as the blue wavelengths of light penetrate water far deeper than other visible wavelengths.
What light do I need for corals?
SPS corals require the most lighting while soft and LPS corals can do well even with lower intensity fluorescent lighting. Actinic or more blue lighting should be used even with metal halide lighting to achieve the best possible coral coloration.
Can fish sleep with blue LED?
Can Fish Sleep in Blue Light? A blue ambient light in an aquarium is meant to mimic moonlight. They are a great addition to any tank as they don’t affect the day and night cycle of the fish or plants and don’t contribute to the growth of algae.
Do blue LED lights cause algae?
Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.
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.
Does actinic light grow coral?
All actinic bulbs will not grow coral. All white bulbs will lack in certain spectrums. Corals need blue and red really. While 420nm might not grow anything, it is still needed to have a full spectrum lighting.
Which Colour light is best for aquarium?
Red, blue and green LEDs are in popular use for standard aquarium lighting since these light temperatures greatly enhance the colors of the objects inside the aquarium. The colors of aquatic plants appear much more rich and vibrant, red fish, shrimp and of course red-leaved stem plants look much flashier.
What color light do fish like?
Best Lighting to Show Fish Colors A very bright light spectrum as a 10,000k light will tend to showcase shimmering shiny or fluorescent on your fish as well as any shades of blue should really start to pop.
What color light do corals need?
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.
Is blue light better for corals?
corals use more of the blue white and humans use more of the white. but take that with a grain of salt, corals can utilize a lot of the light spectrum, however blue light is more useful then white light.
