Aqueon Actinic Blue Aquarium Lamp Deeper water violet light for fish and corals provides the violet wavelengths of light that are found in deeper water and at dawn and dusk. Stimulates neon glow found in GloFish.
Among commonly asked questions is "How long should the aquarium lights be on each day?" Because most aquarium inhabitants and plants come from tropical regions, it is best to mimic the light in this region. Length of daylight varies little in tropical areas, generally lasting 12 hours with an intense period of nine to 10 hours. Keeping lights on for more than 12 hours each day has no practical benefit and can cause algae blooms. It is best to buy an inexpensive timer and automate the light system.

Fluorescent Aquarium Lighting: Coralife Actinic Blue Lamps
With the growing popularity and availability of fish like and decorations like our own line, “glow-in-the-dark” and fluorescent aquariums are becoming more and more common. Most of these animals and decorations are brightly colored in any light but under special lighting, the colors will really glow. There are two main kinds of light that are used in these aquariums: “blacklights” and actinic lights. Knowing the difference between these two can play an important role in making your tank really stand out, as well as in keeping it healthy. For this blog, we will be focusing in general terms only for community aquariums. Aquarium with invertebrates and corals will have different needs since their light requirements are much more specific and extensive.Making the choice between using actinic or blacklights for your glowing aquarium depends on when or how you would like to view it. and are both available with a variety of actinic and blacklight option. Both actinic lights and blacklights make things glow when the light they produce is reflected off of the fluorescent pigments in the object, whether this is light we can see (actinic) or light we can’t (blacklight). These pigments could be in the artificial coloration of an ornament or plants, or in the proteins or cells of a living creature, either artificially or naturally. Many plants and animals that we don’t think of as “glowing” have pigments that are fluorescent under the ultraviolet range. This can help them to blend in or stand out to other animals that can see this range that we can’t. Fish like GloFish have been enhanced with proteins from these fluorescent creatures at their embryotic stages so they can share in these glowing traits.The colors we see around us come from the light’s wavelength, measured in Terahertz (THz) or nanometers (nm). Most people can see light ranging from about 700nm (reds) to about 400nm (purples). Blacklights and both produce light from the bottom of the visible light spectrum (the BIV in ROY G BIV). Most actinic lighting for aquariums has a wavelength of about 420-460nm. The higher end of this range (460nm) produces a more blue color light, while the color shifts to purple approaching the lower end (420nm). This type of lighting is still well within what we are capable of seeing. “Blacklights” emit a light below what we as humans are able to see known as ultraviolet or UV light. Yes, this is the same UV light that we wear sunscreen to protect ourselves against! UV lighting is separated into three major ranges. Blacklight bulbs are UV-A bulbs (315-400nm), the spectrum which causes our skin to tan. For comparison, the UV Sterilizers popular in aquariums for eliminating algae, diseases and parasites are UV-C bulbs (200-280 nm), a destructive spectrum that is mostly filtered out by Earth’s atmosphere and the UV-B range in between is the more damaging rays from the sun that causes sunburn and other harmful conditions.For instance, a popular hood nowadays is the compact Fluorescent hood incorporating an actinic bulb, a full spectrum bulb and a moon light. You could set up the timer to turn on the actinic bulb to go on first and stay on for 12 hours, then have the full spectrum bulb come on an hour or so later and stay on for 10 hours. This could simulate dawn and dusk by having the actinic bulbs come on an hour early and stay on an hour later. Finally, you could have the moon lights turn on when the actinics turn off. Who knows, you may even start to see breeding behavior in certain species that may be more in tune with the light of the moon in this type of setup. Another side benefit of using a moon light is the super cool effect it creates in the aquarium when all the other lights in the room are off.
