Lighting in an Aquarium

The basic role of the aquarium lightning is to allow the fish-keepers to watch their fish. But, what’s more important, it provides the energy to the plants and animals that are photosynthetic. It’s usually the primary and the only source of lightning and it’s of big essence to any system that has plants, coral or anemones that are photosynthetic. The behavior of your fish is also influenced by the source of lightning and their psychology and health and the well-being of the whole tank depends on lightning.

Different set-ups demand different kinds of light fixtures and light bulbs. There are various different lightning options for fish-keepers and their fish, of course. The diversity of types of lightning makes it possible for the aquarists to provide the proper source of lightning for their fish. Tank lightning is grouped into three general types: there’s the common fluorescent lightning, metal halide lightning of high intensity and compact fluorescent lightning. Common output fluorescent lightning or standard fluorescent lightning are the easiest to provide the illumination for an aquarium. Choosing this sort of lightning is best for saltwater-fish-only tanks and fresh tanks, too. There’s a large selection of bulbs made for this sort of lightning and everything seems to allow the fish-keeper to customize tank lightning. You can use different bulbs in order to provide the right kind of lightning for you fish.

Actinic white bulbs create a mild blue or white light that, actually, recreates the marine light. It is a mix of a blue and white actinic light. This light may be pleasing to your eyes and, also help the photosynthetic growth of corals. Color-enhancing bulbs emit warmer and richer colors and really increase the spectrum of colors. They are made to display the colors of your tank’s inhabitants. It’s good for saltwater and fresh-fish-only tanks. Daylight bulbs provide something close to natural sunlight because they emit the wavelengths of already visible light.  The whole color spectrum is also emitted. These bulbs are made for general purposes and ideal for any type of saltwater and fresh tanks. Actinic bulbs provide all kinds of blue of the color spectrum. They imitate the light conditions of deep water and help creating the needed energy for growth of photosynthetic corals. They are appropriate for marine aquariums and coral reef tanks. Plant bulbs provide the light needed for the plants’ growth. Because they emit both blue and red regions of the spectrum of colors, they maximize the photosynthetic activity of plants. High-intensity bulbs emit a crisp white light and are usually combined with actinic bulbs in marine tanks. They imitate a brilliant light that’s found in deep water and they emit a white-blue light. This light appears pretty cool. Compact fluorescents are a higher version of normal output fluorescent lightning. This lightning doesn't have single tube bulbs, but incorporates quad or dual tube bulbs so that greater light is emitted. It can easily replace two normal fluorescent fixtures, and provide as many light as the common fluorescent fixture does. 

They also save a lot of space and are a good choice if you want to upgrade your fish tank and your light system in it. They are nothing more difficult to handle than normal fluorescent light systems, but they still have all the advantages of the normal ones. Compact fluorescents are ideal for marine and freshwater tanks. Metals halide lightning systems have a good reputation among advanced fish-keepers. Unlike other HID system, this one provides a wide range of colors of the color spectrum and the rendition of colors produced by them is well suited for tanks. They are great for aquariums, especially reef tanks, because their inhabitants need high lightning conditions. Metal halide lightning is most commonly used for very large tanks or the ones that are deeper than 25 inches. That’s because of the inability of other systems to provide that much light.


When choosing the right system of lightning for your tank and your fish depend on your taste, the size of your aquarium and the fish’s needs. But, make sure not to experiment with lightning systems that are not made for fish tanks. The health of your fish and the beauty of your aquarium depend on the source of lightning a lot. So, be well informed, and choose carefully.
