Aquarium Lighting: Which is Ideal for my Tank?

Once you decide to bring an aquarium into your home, you will put a lot of time, energy and money into creating a masterpiece aquarium. You have carefully selected the right style aquarium for your taste and placed it in just the right spot in your home. You spent countless hours researching saltwater fish, coral and other marine life to create a balanced and serene aquatic environment.

You’re proud of the masterpiece that you have created and now you should show it off. Lighting is just as important for the aesthetics as it is necessary for your aquarium to grow and flourish. You will want to carefully select it and knowing all of your options will aid you in making the right decision for your aquarium.

Lighting Options

Before you can select lighting, it would be helpful to understand what is available and the advantages and disadvantages of each. In order for your aquarium to thrive and looks its best, it is important to select the lighting that is recommended for your individual underwater community. In this case, one size doesn’t fit all.

Fluorescent Lighting

The most common type of aquarium lighting is fluorescent. One reason for its popularity is that it is the oldest technology available for aquariums. Secondly, it is less expensive than other types of lighting. Not only do they cost less, but they have a low operating cost and emit less heat than other bulbs. However, most fluorescent lights are not compatible with marine life. Full-spectrum fluorescent lights are the only fluorescent lights that can provide the necessary light for a healthy aquarium.

LED Lighting

LED lighting is the newest lighting technology and much more superior to any other lighting on the market. First, the LED bulbs produce considerably less heat than other bulbs and operate at a fraction of the cost of other bulbs. Additionally, these bulbs can last significantly longer than traditional fluorescent or metal halide bulbs. Some people will shy away from LED lighting because the bulbs can be more expensive than other bulbs; however, LED bulbs are the best lighting option for your saltwater aquarium. The LED lights will provide your plants and coral with a good supply of strong light so your aquarium can grow to its full potential. Another benefit to LED lighting is how your aquarium will look. LED lighting will make your whole aquarium seem brighter and colors will be sharper. If you are going to spend the time and money creating your aquarium, don’t you want to show it off in the best way possible?

Metal Halide Lighting

Metal Halide (MH) lights are amongst the strongest marine aquarium lighting available. Metal halides are ideal if you plan on keeping corals that require very high lighting. Metal halides are particularly effective when combined with other types of fluorescent lighting. MH lights are also ideal for deep aquariums because the light can penetrate approximately 24 inches deep. However, MH bulbs tend to produce a great amount of heat and may require that you use a chiller. If financial investment is a concern, it is also good to know that MH bulbs are expensive to purchase. So unless your specific aquarium requires these types of lights, it may be more economical to choose a different type of lighting technology.

There are many aquarium lighting options to choose from. It is important to consider lighting as a factor when purchasing an aquarium. Do your research. Decide on marine life you would like to keep and design your lighting scheme to allow your marine life flourish.

Maintain a Perfect Light and Temperature with Aquarium Chiller and Fish Tank Light

Article by Aquamarinegoods

People have great interest towards aquatic inhabitants and it is due to their interest that aquariums have become a common product in most of the houses. Keeping aquariums at home require lot of care of the aquarium inhabitants as showing negligence towards can affect their life. The life quality inside the aquarium is as good as the conditions that exist inside it. Fish and other aquatic life are quite sensitive to temperature and most of the aquarium inhabitants do well when they are kept in their native temperature. Maintaining a steady temperature in aquarium is quite difficult as sudden change in temperature can lead to disease and death of aquarium inhabitants. Thus, there are many things like aquarium chiller and fish tank light that are required for the ideal aquarium set up.

Things that are part of aquarium setup like lighting system, electrical filtration system and water pump submerged inside the aquarium causes the temperature within the aquarium to rise. Aquarium being closed from all sides have no option of losing temperature to the atmosphere. Beside all these, the hot summer months also contributes in the rise of the aquarium temperature. This is the time when aquarium chiller come handy as it not only helps in reducing the temperature inside the aquarium but it also helps to maintain a steady temperature within the aquarium. This is the most significant use of the water chiller and without aquarium chiller the life inside it is quite difficult and almost impossible.Aquarium chillers that are commonly available are in-line and drop-in chillers, the in-line chillers are installed just adjacent to the tank and coolant is fed with the help of an external probe, which is placed in the water. Different types of aquarium chillers are available for different capacity of aquarium. In small saltwater or freshwater aquariums thermoelectric chillers are used, which are considered as best for the tank having capacity of below 60 gallons and that has a slow water flow. Large aquariums usually make use of the in-line chillers. The in-line chillers are available in variety of capacities and hence can be used with different aquarium tank capacity. This chillers require plumbing and therefore they need to be installed with proper planning and is best to install at the time of installing the aquarium only.

Besides aquarium chillers another significant accessory is the fish tank light, which is vital to provide ideal lighting conditions to the aquatic inhabitants. Aquatic inhabitants like fish, reefs and plants also require seven to eight hours of light like the human beings for their proper growth. Among all the options available in the fish tank lights, LED lights are the most preferred among the marine and reef hobbyists. LED fish tank light is preferred because it offers high intensity light while producing low heat, which is preferred in saltwater reef systems that requires low water temperature. This light also have good controllability of color spectrum and output of the light. Today people need to carefully select an aquarium chiller and fish water tank for successfully keeping and managing an aquarium.

Aquarium Lighting

Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (January 2008)Aquarium lighting describes any type of light that is used to illuminate an aquarium tank or in some instances, such as with reef aquariums, support the life contained within. FreshwaterFreshwater aquarium lighting often comes in two forms; one is a screw-in style incandescent bulb and the other is normal output fluorescent lighting. Screw-in compact fluorescent lighting is also used in freshwater aquaria since it provides brighter light output than traditional screw-in style bulbs.More demanding freshwater set-ups, such as planted freshwater aquariums, may require stronger light sources. Compact fluorescent bulbs, high output T5 bulbs or metal halide lamps are often used over such aquariums to encourage plant growth. While these lights can provide a better spectrum than traditional ones, they often use more electricity and have a high heat output. ReefThe reef aquarium field is where aquarium lighting varies the greatest. Some reef aquarium keepers use VHO (Very High Output) fluorescent tubes, compact fluorescent lighting, and metal halide lighting since they provide much brighter light than average fluorescent bulbs and come in a variety of spectrums. Reef keepers often opt for light of varying spectrum. Since many corals require a deep blue or actinic spectrum of light to thrive many aquarists must supplement traditional white light with light of this color. Also popular with reef keepers is T5 High Output fluorescent bulbs. These bulbs are thinner than traditional T8 bulbs and provide a much brighter, more powerful light.Another light source in reef aquariums today is metal halide lighting. These high output lights closely recreate the shimmering effect of bright tropical sun over a patch of coral reef. Metal halide bulbs come in a variety of spectra from 5000k on up to “20,000”k and allow for a variety of light hungry corals to survive under them. Many aquarists will use metal halide bulbs in conjunction with either power compact fluorescents or T5 fluorescents since halide lighting does not have the overall balanced effect of other light types. While very useful to reef aquarium keepers, halide lighting also uses a lot of electricity (150-400 watts being common)and produces copious amounts of heat. Most reef keepers mount halide bulbs at least one foot above their tank and some, due to the lights’ heat output have had to add chillers to keep aquarium water cool.Many light fixtures come as all-in-one units with light for both daylight hours and nighttime viewing. LED lamps of 3/4 to 2 watts can be implemented to come on at night, simulating the glow of the moon over the tank. All in one fixtures require large fans to cool the bulbs and achieve maximum light efficiency. LED lighting is also becoming more common for not only lunar lighting but also to simulate daylight conditions, LEDs have a higher initial cost than other lighting sources but utilize much less energy. They are also dimmable. LEDs produce a very narrow color spectrum that is limited to a narrow band of wavelengths. For this reason an array of different colored LEDs is required to be used in combination to simulate spectral coverage that is suitable for coral growth. Early adopters of pure LED based systems have reported that the limited color spectrum provided by LEDs may not produce optimal coral growth.v  d  eAquarium and fishkeeping hobbyTypesFreshwater aquarium Marine aquarium Brackish water aquarium Community tank Biotope Reef aquariumAquarium equipment and furnitureFilter Berlin Method Protein skimmer Deep sand bed Heater Refugium Calcium reactor Bog-wood and Driftwood Airstone Live rock Substrate Fishcam Aquarium fish feeder Aquarium lightingFish termsHardy fish Dither fish Algae eater Bottom feeder Tropical fish Coldwater fish Painted fishFish foodFlake food Feeder fish Bloodworms Brine shrimp Tubifex tubifex Daphnia InfusoriaListsList of freshwater aquarium fish species List of freshwater aquarium plant species List of freshwater aquarium invertebrate species List of marine aquarium fish species List of brackish aquarium fish species List of aquarium diseasesOther termsAquascaping Spawning triggers Reef safe MacQuarium Bath treatmentAquarium magazinesPractical Fishkeeping Tropical Fish Hobbyist Koi Aquarium Fish InternationalPeopleTakashi Amano Herbert R.

Know about Aquarium Lights

Article by Lighting

Different aquariums need different types of light strength. On one end of the spectrum there is red light, which can only penetrate a short distance. At the other end is blue, which can go further into the water. Most fish are fine with yellow or green light; however, many aquarium plants need blue light to help them grow. There are several types of lighting available on the market for your aquarium.

Normal Florescent BulbsNormal Florescent or NO usually comes with a regular aquarium tank. This is enough for a fish-only setup. The NO bulbs tend to be cool and efficient; however, they are the least penetrating fluorescent bulbs. In aquariums with plants, they might be used as supplemental lighting.

High Output BulbsHigh output (HO) lights are available as T5 bulbs, which are smaller than the normal fluorescent. They emit more heat than the NO bulbs, but they usually come with a built in system to cut down on heat.

Very High Output BulbsVery High Output (VHO) comes in a variety of sizes; one of the most common is the T12. Although these bulbs emit heat, they don’t emit as much as a metal halide bulb. You get a more powerful light than the standard fluorescent. Unlike the metal halide, you get an even light source throughout your aquarium tank.

Power Compact LightsThese bulbs are designed slightly differently from the rest of the fluorescent bulbs. They have only one end cap attachment rather than the standard two, and the bulbs are available in different shapes from twin to square and triple. The bulbs are more efficient and powerful than other fluorescent bulbs. Power compact lights are smaller than normal fluorescent lights.

Metal HalideThis is a high intensity aquarium bulb that produces a focused light. The bulbs are used in freshwater and saltwater aquariums with plants and coral reefs. You will need to use a water chiller with these lights because they heat the water up and you might need a UV shield to cut down radiation. The bulbs are expensive and should be handled with care.

LED LightsLED is not technically a light, but a light emitting diode. It is good for night time viewing of nocturnal fish.

LED aquarium lighting is most commonly used for nighttime lighting but has recently gained traction as being the main light source. Using an aquarium moon light has many benefits, especially for reef tanks. Moon lights complete the day/night cycle and can be synced with a timer to match the lunar cycle. Doing so can stimulate coral spawning and create great nighttime viewing. In addition to creating a cool shimmering moon light effect, LED lunar lights give you a window into what your nocturnal pets do at night. Using LED lighting as the main light source also has many benefits. LED bulbs are extremely energy efficient and last up to 5 years (50,000 hours). LED lights produce very little heat, are highly customizable and among the most handsome (and small) fixtures on the market today.

Saltwater Aquarium Lighting

Article by richard

The type of lighting that we will select for use in our saltwater aquarium is largely dependant upon the grouping of livestock that we will select to inhabit the tank. Regular cycles of light are commonly used to simulate day and night for fish and invertebrates. This encourages a feel of a natural environment among our livestock, cultivating the proper periods of rest and similar such circumstances that are most conducive to their successful and healthy adaptations to our aquariums.

Tanks containing only fish and live rock do not commonly require overly specific lighting techniques. However, invertebrates and the required propagation of various forms of algae that are commonly needed indeed calls for more specific and customized lighting. Choices for lighting our tanks include natural sunlight, Light Emitting Diode (LED), various forms of fluorescent bulbs, and metal halide lights.

Natural sunlight is only effective as a light source for a saltwater aquarium in geographic areas located in the vicinity of the equator. This is due to the levels of intensity of sunlight found in such areas. Such aquarist techniques involving the use of sunlight and in the vicinity of the equator are only implemented among large reef tanks. In tanks that are much more commonly found among hobbyists throughout the world, natural sunlight is avoided as a light source as it is potentially detrimental to many forms of livestock for a variety of reasons.

LED sources have a great deal of potential. The jury is somewhat still out on the extent of their practicality and effectiveness, however, so it can depend on which expert we ask as to how they will evaluate LED. One way or the other, the aquarist community would be well served to keep a watchful eye on evolving technological developments among LED light sources, as implications currently include advances in lighting schedules, simulations of lunar lighting, and even the effective simulation of cloud coverage.

Different types of fluorescent bulbs all have about the same intensity, but it is their various shapes and reflectors that result in their unique specifications. The newer fluorescents have improved reflectors, allowing more amounts of light into the aquarium than in years past. The more recently designed bulbs are a bit more costly to maintain than their predecessors, so some aquarists continue to use traditional fluorescent lighting sources.

Metal halide lights are comparable in practicality to fluorescent lighting. Many aquarists consider the primary difference to be that metal halide may be concentrated into specific areas of the tank while fluorescent light is distributed evenly. Metal halide lighting systems are usually more of a financial investment than fluorescent lights, but are required for certain reef tanks.

Overall, it will depend on the specific types of livestock that we desire to maintain as to the importance of our choice for lighting. This is of course directly related to the amount that we should be willing to invest in our lighting and the extents that we will go to achieve and maintain our optimal light conditions.

Fish keepers tips – how to choose aquarium lights

Article by Lighting

Aquarium lighting can be very confusing for many novice fish keepers, there are many different types of bulbs or set ups to choose from and to make things even worse the actual choice of tubes to fit into the units can vary dependant on which livestock that you are keeping. The lighting can be very important for many aquariums; corals in a reef aquarium require the brightest of lighting, as the actual corals are usually light dependant.

Lighting in the aquarium is not just a tool that allows us to observe our aquarium and the inhabitants, it is also required to aid plant growth with photosynthesis and some species of fish prefer bright lighting to be at their best. Many species of fish prefer subdued lighting so this is why there is such a large choice of lighting available to us.

Some of the most common systems include the following tubes

Actinic/White tubes- these are commonly used in marine aquariums as they emit a strong white light as well as light from the blue range of the spectrum which is very important for the corals in the aquarium. They tend to give a nice hue in the tank making it perfect for viewing as well.

Day-Glo tubes- these provide light from the full spectrum thus replicating sunlight hitting the water, you will often see these used in a general tank set up or a community tank.

Color-Glo tubes- When you are after a softer light, these tubes are ideal, they emit a soft glow by using colors from the other end of the spectrum, namely yellows and reds. They are ideal for fish that do not like bright lighting and the tank looks cozy when using these.

Plant-Grow tubes- These are specially designed for planted aquariums and emit light from the red and blue color spectrum. Photosynthesis is enhanced with this lighting thus producing better growth and foliage color from the plants.

High Intensity tubes- These are really powerful and are used to penetrate the deeper reef aquariums so that the bottom dwellers do not miss out on the light source. They have a high Kelvin rating, often up to 20,000K and emit a white/blue light.

As mentioned above there are now choices which type of lighting system we can use, Metal Halides are now very popular with the reef aquarist, they emit a high lighting level but they do use a lot of power to keep the aquarium illuminated.

LED systems are also entering into this hobby and are a lot cheaper to run that all of the other systems, there is a drawback though, they are still very costly to purchase from new. This system does not use tubes but has rows of LED lights that perform the same function(ie LED aquarium lights).

When selecting your lighting always check the amount of lighting that is required to illuminate the water volume in your tank and never use less than is advised, remember that this can be affected by the depth of the tank as well. Always use timers to run your lighting system and never leave the lighting on for too long as this can also encourage algal growth in the aquarium.
