Keeping an aquarium is passion with many people but maintaining it is quite a job. One has to take care of many things so that fish inside the tank might remain safe and healthy. Fish are fragile creature so they need a lot of life-supporting systems to live. Besides continuous supply of fresh water, you need to have aquarium light in the tank. It is must to get the light as it supports life inside the aquarium besides making the aquarium look really beautiful. For the owners looking for lights for the tank, there are many choices available in the market. Apart from the lights, you would also need a good aquarium pump to supply water supply as well as clean out the used water from the tank.
While looking for the aquarium light, you should have an idea about what are your requirements. It is imperative that buying the lights fulfill all your needs. Apart from fulfilling the needs, the lights would also make the aquarium look attractive. Buying beautiful lights would add great beauty to the room in which it is placed. Most of these lights have got fabulous features would be very useful for the users. No matter where you keep the aquarium, lights will add a certain grace and beauty to the space. Not only the lights but the aquarium pump will also prove to be quite useful for maintain the aquarium in a better way.
Moreover, the aesthetics of the room will also be greatly enhanced by installing a beautiful aquarium light. However, it is recommended that you should search the market before going ahead with the purchase. It is better to assess your requirements and then go ahead with the purchase. All kinds of lights are available in the market. Over the last few years, mushrooming of online stores have added another dimension to shopping. Now, you shop online for lights sitting from your with a click of your mouse and the ordered product will be delivered at your doorstep.
All stores, online as well as on-site, offer a wide variety colors for your aquarium light. Many a light come with timers for dawn and dusk effects. What is more, the lights are kept cool by high powered internal fans. Many aquarium owners prefer LED moonlights for their fabulous effects. And, one can find these lights for aquariums of all sizes. You can find that numerous reputed brands offer these fantastic lights for fish tanks.
With the advent of newer and better technologies, increasing intensities and a growing spectrum, there are many options to consider.
Many, if not most aquarium corals contain within their tissue the symbiotic algae called zooxanthellae. It is these zooxanthellae that require light to perform photosynthesis and in turn produce simple sugars that the corals utilize for food. The challenge for the hobbyist is to provide enough light to allow photosynthesis to maintain a thriving population of zooxanthellae in a coral tissue. Though this may seem simple enough, in reality this can prove to be a very complex task.Some corals such as mushroom corals and polyp corals require very little light to thrive. Conversely, large-polyp stony corals such as brain coral, bubble coral, elegance coral, cup coral, torch coral, and trumpet coral require moderate amounts of light, and small polyp stony corals such as Acropora, Montipora, Porites, and Pocillopora require high intensity lighting.
Of the various types, most popular aquarium lighting comes from metal halide, very high output or VHO, compact fluorescent and T5 high output lighting systems. Although they were once widely used, many reef tank aquarists have abandoned T12 and T8 fluorescent lamps due to their poor intensity, and mercury vapor due to its production of a limited light spectrum.
Recent advances in lighting technology have also made available a completely new technology for aquarium lighting: lightemitting diodes (LED aquarium light). Although LEDs themselves are not new, the technology has only recently been adapted to produce systems with qualities that allow them to be considered viable alternatives to gas- and filament-basedaquarium lighting systems. The newness of the technology does cause them to be relatively expensive, but these systems bring several advantages over traditional lighting. Although their initial cost is much higher, they tend to be economical in the long run because they consume less power and have far longer lifespans than other systems. Also, because LED systems are made of hundreds of very small bulbs, a microcomputer can control their output can be controlled to simulate daybreak and sunset. Some systems also have the ability to simulate moonlight and the phases of the moon, as well as vary the color temperature of the light produced.
The choices for aquarium lighting are made complicated by variables such as color temperature, (measured in kelvins), color rendering index (CRI), photosynthetically active radiation (PAR) and lumens. Power output available to the hobbyist can range from a meager 9 W fluorescent lamp to a blinding 1000W metal halide. Lighting systems also vary in the light output produced by each bulb type—listed in order of weakest to strongest they would be: T8/12 or normal output lamps, compact fluorescent and T5 high output, VHO, and metal halide lamps. To further complicate matters, there are several types of ballasts available: electric ballast, magnetic ballast, and pulse start ballast.
