Buyers’ Guide

Do I really need lights for my aquarium? 

Yes. While most aquarium kits come equipped with built-in lighting, if your aquarium doesn’t have a lighting fixture built into it, we strongly urge you to buy lights for it separately. Aquarium lighting is an essential piece of equipment that can definitely not be skipped. 

Firstly, you need the lights for the aquatic life inside your aquarium. Your fish need a constant regular pattern of light and darkness in order to develop healthy sleeping patterns. Aquarium lighting is also specifically built to simulate sunlight and moonlight which is very beneficial for your fish. It relaxes them and helps prevent stress-related diseases. 

If you have live plants inside your aquarium then having lighting for it becomes even more necessary. Plants require light in order to photosynthesize and grow properly. You can’t expect to have healthy aquarium plants without decent aquarium lights. 

Lastly, you’ve bought an aquarium that’s going to have fish and plants of beautiful, brilliant colors. It would be a shame if you didn’t invest in aquarium lights that would be able to show off their beauty effectively. 

What are some aspects to keep in mind when purchasing aquarium lights? 

There are a number of factors you can keep in mind and ponder over which will help you make an informed decision while buying aquarium lights. Some things you should look out for when buying aquarium lights are: 

  • Material 

If you’re ordering online, you will only have online reviews to go off of and make an estimate but if you’re purchasing your aquarium lights at a store in real-life, we urge you to properly inspect your aquarium light to make sure it’s made from high-quality material that will last you a while.

Inspect the fixture that’s used to house the LEDs, ask if it’s waterproof or water-resistant, inquire about the lifespan of the LEDs inside. All these aspects play a great role in how much value you will be able to get out of your aquarium so it’s important you inquire about these things from the manufacturer before you make your purchase. 

  • Cost 

We highly recommend you don’t skimp out on lights as they can be just as important for the welfare of your aquatic fish and plants as your aquarium itself. 

Obviously, you should get aquarium lights that will provide the greatest effectiveness when it comes to the illumination of fish and the effective growth in live aquarium plants but you should also do this while keeping in mind the money you have in your pocket. 

Often times, a lot of aquarium lights have high prices because they are packed with features that everyday fishkeepers usually don’t need. It’s important you do your research to make sure you’re not spending money on a product that’s expensive because of a feature that isn’t even necessary for the type of fish or aquarium plants you have. 

  • Aquarium Size

This goes without saying but you should definitely shop for an aquarium light that is appropriately sized for your fish tank. If you get one that’s too big, it might be too overbearing your fish, if you get one that’s too small, it might not fit and might not be enough to illuminate the entirety of your aquarium effectively. 

What are the different types of aquarium lights?

Lights for aquariums are usually divided into four categories. These categories are: 

  • Normal Output Fluorescents

These versatile lighting systems offer an easy way to light an aquarium. They offer light that is suitable for both freshwater and saltwater fish-only aquariums. Different types of bulbs are often utilized together in order to produce lighting that is most appropriate for one’s aquarium. 

  • Compact Fluorescents 

These are higher output versions of normal fluorescents. They consist of dual or quad tube bulbs that give out a higher light output. They are appropriate for aquariums that require high-intensity lighting. 

  • Metal Halides 

Metal halide lights are high-intensity lights that are very popular among more veteran aquarists. They have a reputation for having immensely high penetration power in the water in large or deep fish tanks. They are also notorious for heating up the water drastically so you normally have to invest in a chiller if you’re going to use metal halide lights. 

  • LEDs 

LEDs stand for light-emitting diodes and they are currently taking the aquarium world by storm. They have quickly risen to the top as the most popular option for lighting aquariums due to their compact size, easy-to-use nature and infinite customizability.

Can I build my own lights for my aquarium?

You can definitely opt to build your own lighting setup for your aquarium but as you can imagine, this would be much more resource-intensive and time-consuming. We recommend you don’t do this if you’re a beginner as you might end up with a final product that is inadequate for lighting up your aquarium.

Do fish sleep when I turn off my aquarium lights?

Yes. As we mentioned earlier, fish need a regular cycle of light and darkness in order to develop sleeping patterns and healthy circadian rhythms. If you turn your aquarium light on at night, you can see your fish swaying around gently as they’re resting. 

Frequently Asked Questions (FAQs)

What type of light is best for freshwater aquariums?

Out of the four options that we’ve discussed above, your best option for lighting freshwater aquariums is definitely LED lighting. LEDs give you the liberty of customizing and choosing the intensity of light for your aquarium. LEDs also utilize electricity a lot more efficiently. Freshwater aquariums are often small in size and come in the form of desktop and tabletop aquariums. LED lights are perfect for aquariums such as these due to their compact size and flexible nature. 

How do I measure the intensity of light in my aquarium? 

When we’re talking about the amount of light needed to light up an aquarium, the intensity of light is usually measured in watts per gallon. 

How much light does a reef tank need?

Reef tanks often require a lot more light than freshwater tanks or saltwater fish-only tanks. As stated above, the intensity of light when talking about aquariums is measured in watts per gallon and a reef tank normally requires anywhere between 4 – 8 watts per gallon of light. For example, if you have a 20-gallon coral reef tank, you will require an aquarium light that operates anywhere between 80 and 160 watts. 

How much electricity is generally required by aquarium lights?

As you can probably imagine, this has a lot to do with how big your aquarium is and how intense your aquarium lights are. You can get a good estimate of how much electricity your aquarium lights will use by looking at their operating capacity. 

For example, freshwater aquariums normally require anywhere between 3 – 5 watts per gallon of light for 10 – 12 hours a day. So if you have a 20-gallon freshwater aquarium, you will require a light that will be operating anywhere between 60 – 100 watts every day for 10 – 12 hours. 

How high should aquarium lights normally be hung above the water surface?

You can get a good estimate of this just by eye. We recommend turning off all the lights in your room and judging how intensely your lights illuminate your aquarium as you adjust its height above your aquarium. 

As a good rule of thumb, any height equal to or above 24 inches from the surface of the water is appropriate for most aquariums unless you have an exotic species of fish, plant or coral which require special lighting conditions.

Can I leave blue light on in an aquarium as a night light?

Blue lights often allow humans to observe what nocturnal fish are doing during “nighttime”. However, this can sometimes be disturbing for them if the lights are too bright. 

Owners with nocturnal fish often invest in red lights. To the fish, this comes off as darkness whereas it allows us to observe them. 

Do Neon Tetras require light at night?

Like most fish, Tetras also require about 12 hours of light each day with 12 hours of darkness in order to develop regular sleeping patterns. Some species such as Neon and Glowlight Tetras enjoy subdued lighting during the night.

Does blue-colored light bother or annoy fish? 

They’re not necessary for most freshwater aquariums but there’s no harm in having them either. Most fish don’t care if you have blue-colored lights in the aquarium. Just make sure they aren’t overbearing to the point where they may be stressful for your fish. The only real thing you have to worry about is the intensity of the light shining over your aquarium.

Are LED aquarium lights cooler? 

Yes. LEDs are widely known to operate at immensely cooler temperatures than incandescent or fluorescent lights.

Can fish in my aquarium see the color of the light? 

Yes. Fish retinas have rod and cone cells which can help them detect the colors of the light that’s shining into the aquarium. Some species of fish can even see ultraviolet light while other species are highly sensitive to polarized light. 

Final Verdict

Aquarium lights are a piece of equipment that is just about as essential to the successful running of a household aquarium as the aquarium itself. 

After long arguments and research, we’ve decided that the NICREW ClassicLED Aquarium Light is definitely the best aquarium light out there. It features insanely effective features all at a very modest price.
