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.

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.For daytime viewing, an actinic light is a better choice since it produces more of a brighter light that we can see and less UV radiation that can be harmful to some more sensitive organisms in higher concentrations. Blacklights are a good option for nighttime viewing only, when you may not want to see anything in the aquarium other than those fluorescent glowing objects or fish. You may choose to use one or the other of these lights or a combination of them or more standard “white” lighting which contains a balance of the entire visible light range. Lighting an aquarium containing glowing elements with a more traditional white light or “50/50 bulb” (half white light, half actinic) during the day and changing to an actinic or blacklight at night can truly give you a dramatic change to the look of your aquarium with no more effort than the flip of a switch!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.Artificial vs. Natural beauty... Becoming a common sight in pet stores - Glo-fish. The fish were genetically altered with a protein gene originally injected from jellyfish to make them fluorescent in an aquarium fitted with black light. Welcome to the future.
