LED Aquarium Lighting For Freshwater Aquariums

A better and healthier freshwater aquarium requires the proper illumination. For your tank, light-emitting diode (LED) illumination offers a number of benefits. There are several options available for this kind of illumination, giving you more possibilities than with conventional incandescent, fluorescent, or metal halide lights. However, you must make a sensible choice to make sure you obtain lights with the proper spectral range and brightness to sustain the vegetation in your tank and prevent the spread of algae.

LED Vs. Other Lighting Options

Standard fluorescent lighting, compact fluorescent lighting, metal halide lighting, and LED lighting are your best choices for freshwater aquarium lighting. Avoid using incandescent bulbs because they are only suitable for tiny aquariums and can produce excessive heat.

Standard fluorescent lights have a good light output and minimum heat production. Compact fluorescent bulbs, which produce more light while taking up less space, are frequently used in aquarium hoods. Due to their complete spectrum, metal halide lamps are better at simulating the tropical illumination that several freshwater fish experienced in their natural habitat and can support photosynthesis in aquarium plants. They can, however, produce a significant amount of heat.

LED lights, in comparison, operate significantly more coolly than conventional fluorescent and metal halide lighting. As long as you choose those with the correct output, they feature a variety of adjustable illumination colors and intensities and work well in both fish-only and planted tanks.

The Pros

To profit from the advantages of this sort of lighting, you could wish to install new LED lighting or upgrade the LED lighting on your current tank. These consist of the following:

Low Energy Requirements

LED lights require considerably less energy to operate. Compared to other aquarium lights, LED lighting is more energy-efficient. Within the first 12 to 18 months, your energy cost reductions will be enough to cover the difference in the price of an LED system.

Low Heat Output

Since LED lights don’t produce as much heat as incandescent and fluorescent bulbs do, they won’t raise the temperature of the water in your aquarium. To prevent the heat, they emit from shortening the LED chip’s lifespan. They still require sufficient air circulation. Thus, they should be kept from other hot lighting sources.

Long Life

The fact that LED lights endure so much longer than other conventional types of illumination is a highly well-liked benefit. Compared to incandescent bulbs, which last between four and twelve months, ordinary fluorescent bulbs, metal halide bulbs, which last between six and eighteen months, and compact fluorescent bulbs, which can last up to 28 months, LED lights have a lifespan of up to 50,000 hours or over six years. Although they are more expensive upfront, you will be saving the money you would spend on replacement bulbs for metal halide, T5, or compressed fluorescent bulbs over the course of five years.

Adjustable Light Intensity

This is especially beneficial for nocturnal fish because it allows for feeding and observing while simulating moonlight in the tank. Even LED lighting panels that mimic the lunar cycle every month exist. Using a remote or an app on your smartphone to change the lighting can be entertaining. Alternately, let your smart light source choose the appropriate colors and wavelengths based on the temperature and stage of plant growth.

The Drawbacks

Although LED aquarium decor has some drawbacks, there are some restrictions that must be taken into account.

Availability

A lot of aquarium kits with lights or hoods with lights do not include LED lights. The Eclipse systems, a popular combo device, are only available with regular fluorescent light bulbs. However, you can upgrade your Eclipse hoods with LED choices. Similarly, fluorescent lights are still available in some light fixtures.

Cost

 LED fixtures are often a little more expensive to buy initially. Although you will ultimately compensate for this by saving energy as well as in the cost of replacing bulbs, your original budget might have to be higher.

Used For Planted Aquariums

The use of planted aquariums is a further major weakness. Only low to medium illumination needs are suitable for many LED light fixtures. That will work well for many plants as well as almost all fish. The ideal Kelvin ratings for the majority of planted aquariums are 6500K to 7000K. You must look for suitable LED lighting alternatives for plants with high light requirements, though.

New items are fast expanding the LED market. Most analysts concur that LEDs have a promising future.

How Should LED Aquarium Lighting Be Selected?

There are more factors involved in selecting the best aquarium light than just personal choice and price range. It has to do with the fish community in your tank as well as the setup you have there. When purchasing an aquarium light, remember that each tank setup has different illumination requirements.

For Planted Freshwater Tanks

Because live plants require adequate light for photosynthesis to take place, planted tanks tend to have more demanding lighting requirements. When purchasing a LED Light source for planted tanks, the proper type and adequate number are the two main considerations.

Color temp (Kelvin grade) is used to select the best kind of aquarium lighting. The greater the Kelvin value, the bluer the lighting is. The Kelvin value of light decreases as it becomes redder. Aquarium plants can tolerate a broad variety of color temperatures; however, for optimal plant development and aesthetics, the white spectrum from 5500 to 7500 K should be used.

The most effective unit for measuring is PAR (photosynthetic active radiation, measured in mol/m2/s). The PAR gauges how much sunlight is available for photosynthesis and plant development. You may use this dimension to decide whether a product can provide your planted tank with adequate light.

The optimal light must be intense enough to illuminate the tank and meet the photosynthetic requirements of your plants. To ensure that each plant receives precisely the right amount of light for its needs, you will need to install several light-demanding plants in various locations around your tank.

For A Tank With Just Freshwater Fish

less lighting is required in freshwater fish-only aquariums for you to view the fish and for the fish to look for food. The sort of light you select will mostly rely on the species of fish in your tank because different fish species have varying lighting requirements.

The majority of freshwater aquarium fish come from shallow streams with lush foliage above, where they typically get 10 to 12 hours of shady sunlight each day. The greatest reproduction of this type of light is a 5500–8000K aquarium light.

Some fish kept in aquariums are bashful, while others enjoy hiding. When purchasing the light, this needs to be taken into account. The fish may feel uncomfortable if the illumination is too strong. Multiple dark, hiding spots can be added to a tank with fish that both enjoy and dislike light to solve the problem and keep the shade-loving fish happy.

 Finnex Fugeray Planted+ Aquarium Led Light

The elegant metal housing of the Finnex FugeRay Planted+ aquarium is thin. White LEDs, “true red” LEDs, and a number of blue LEDs are included in the fixture.

The manufacturer advertises the red LEDs in the FugeRay as “true red” 660nm bulbs. According to studies, this sort of bulb produces one of the most effective wavelengths for photosynthesis. The best way to determine what your tank responds to is to experiment on your own, but at the lowest level, the red LEDs will offer your aquarium a rudder, warmer color tone.

In contrast to the Planted+ 24/7 that we previously evaluated, the FugeRay does not come with a 24/7 cycle. It does contain blue lights (along with the “true red” LEDs we keep emphasizing) for the night light setting.

This fixture comes in seven sizes:

  • 12”
  • 16”
  • 20”
  • 24”

  • Decent brightness.
  • Attractive light tone.
  • Smooth exterior.

Cons

  • Secure mounting is lacking.
  • Some variants of bigger fixtures bow in the middle.
  • Although the timer is pre-wired, it is not included.

Marineland Led Aquarium Light

Although it isn’t the most stylish fixture available, the MarineLand LED Tank Lighting nonetheless does the job. Although it is more obvious than its thinner cousins, it is not offensive to the sight.

For this fixture, unlike the Finnex types we previously examined, there is no plastic splash protection. This suggests that you probably need a cover (glass is recommended by Marineland). If you have a Marineland hood and want to substitute the fixture that’s presently there, several users advise that somehow this fixture could fit in it.

This light is only available in one size, which is 11″. Although some users claim this light is suitable for tanks up to 40 gallons, the majority of users use it for tanks between 10 and 20 gallons.

Aqua illumination Hydra Twentysix Hd

The newest development in the Hydra series is the Aquaillumination Hydra TwentySix HD.

The HD label is focused on the fixture’s capacity to utilize energy from LEDs (colors) that are not in use to increase the output of LEDs that are employed during the 24-hour lighting cycle. For a suitable mix of light distribution and focusing strength, the Hydra TwentySix HD employed 80-degree focusing lenses. At full power, the Hydra consumes 90 watts. The aquarium water remains cold thanks to the aluminum fixture housing’s effective role as a heat sink.

Brand-name LEDs from Cree, Osram, and SemiLED are used in the lighting. An external controller is not required for the Hydra fixtures. Through the myAI software, they may be manually set up or remotely operated by a computer or smart device.

You can buy it here.

What Is The Best Light Schedule For A Freshwater Fish Tank?

The next step is to determine how to use the aquarium light to your advantage in addition to benefiting your plants and fish. The majority of freshwater plants and fish require 8 to 12 hours of white light every day. To ensure that your aquarium receives the same quantity of light during the same period of time each day, you should put your lighting system on a timer. It’s important to remember that the residents in your tank depend on the darkness just as much as they do the light.

The simplest method to get your aquarium’s balance just perfect is to try to mimic nature. There are aquarium lights with timers that ramp up and down gradually to simulate dawn and dusk. You may change the light intensity using these as it changes throughout the day. These alternatives are ideal for freshwater aquariums.

It’s also crucial to have a peaceful blue moonlight—created by a number of blue LEDs—and/or a time of darkness at night. To survive, both plants and fish need a healthy ratio of day and night. If the aquarium receives too much light, the plants may become scorched, the fish may become stressed, or algae growth may begin.

How Many Hours Of Illumination Do Plants In Aquariums Require?

The majority of aquarium plants require at least 8 hours of light each day to survive. However, with a 12-hour light cycle, the majority of aquarium plants will develop more quickly and robustly. The ideal light hours might change based on the light’s intensity and the particular needs of your plants. As there are numerous factors to take into account, it is recommended to experiment and modify the light cycle as necessary.

Remember that more light isn’t necessarily a good thing. For instance, if you provide excessive light, you can have too much algae development. This is particularly true if your vegetation is just getting started in the aquarium and is still young.

FAQ

Which Lighting Kind Is Ideal For Freshwater Aquariums?

Standard fluorescent lighting, compact fluorescent lighting, metal halide lighting, and LED lighting are your best alternatives for freshwater aquarium lighting. Avoid using incandescent bulbs since they are only appropriate for small tanks and can produce excessive heat.

The Ideal Hue Of Light For Freshwater Aquariums?

FULL RGB SPECTRUM.

It’s our go-to spectrum, and we STRONGLY advise using it for the majority of freshwater tanks. Nothing enriches your tank and brings out the vibrant hues like a complete, rich RGB (Red, Green, Blue) range of light. It doesn’t just make your fish’s colors pop; it also inhibits the formation of algae.

Are Blue Lights Required In Freshwater Aquariums?

The color spectrum that is least involved in photosynthesis and that our eyes respond to the best is green. For both marine and freshwater reef aquariums with plants, the blue wavelength is likely the most crucial component of the light spectrum.

Do Fish Feel Stress From Aquarium Lights?

Since aquarium fish don’t really require light, it is better to turn it off at night. As fish require a time of darkness to sleep, keeping the light on might stress them out. A dirty-looking tank will result from algae that grows too quickly under too much light. Do not end up leaving your lights on, is the quick response.

Conclusion

Knowing the fundamentals of planted aquarium lighting, you are aware that the solution is not straightforward. You must provide answers to the following questions for yourself:

  • What are you attempting to achieve? Are you aiming to compete in an international aquascaping competition, cultivate your first aquarium plants, or sell plant seeds for a profit?
  • What sort of vegetation do you wish to cultivate, and how much PAR do they need in terms of light intensity?
  • What are the aquarium’s dimensions, and how numerous lights will you need to illuminate it?
  • What is your spending limit, as well as which light will provide the most value?

There is nothing wrong with selecting a cost-effective lamp that works well for maintaining low-light plants when you are initially beginning to plant tanks. The more expensive choices, though, can be worthwhile to explore whether you have some money saved up. These higher-quality lights frequently have longer lifespans and are covered by manufacturers’ extended warranties. Intriguing aspects include the capacity to alter the color spectrum, reduce the intensity, and replicate the gradual dawns and sunsets observed in nature.
