Reef Aquarium and Corals

Choosing to start a salt water aquarium rather than a fresh water aquarium means that you can choose to include soft or hard corals within your tank.
Many people confuse corals as being inanimate objects or rocks, but this is a complete misconception; corals are in fact animals, which is why they require a specific environment in order to survive.

Hard corals are typically seen as the easier of the two species to keep, as they are less sensitive to fluctuations in homeostasis within the aquarium.

Hard corals fall into one of two categories

  • LPS which stands for large polyp stony

  • SPS which stands for small polyp stony.

Though similar, most laymen are probably familiar with SPS species, which are the more commonly seen varieties in the natural world.
Of the two, most people consider LPS corals to be easier to keep and maintain.

SPS corals are more susceptible to imbalances of nitrates and phosphates, as well as requiring a great deal of light, a strong flow of water, and being very sensitive to temperature fluctuations.
Therefore, it is far easier to encounter problems with this variety.

When it comes to growing coral for your marine, saltwater aquarium, the clear front-runner of the lighting options available to you is LED lighting.

In comparison to alternatives such as fluorescent lights, LEDs have a number of advantages , including far greater energy efficiency and lower power consumption, the ability to support a full spectrum of color and other lighting effects, and vastly superior longevity and lifespan.

To make the most of your new LED lights, we’ve put together a list of tips for choosing LED lights, as well as some things to do and things to avoid when setting up an LED lighting system.

How to choose the best LED aquarium lighting for corals

When you’re selecting a coral LED lighting, you should take the following points into consideration to be sure that you get a product that is suited to you and your tank:

  • Consider the coverage offered by your LED lights. The shape and angle of the included lenses will directly affect the angle at which your lighting is projected. Typically, 90-degree angle lenses result in very focused light and less coverage in larger tanks.

  • Consider what color LEDs a unit includes. The phrase ‘full spectrum’ means that a product covers all wavelengths of light. This is particularly useful in tanks where the inhabitants include fish, plant life and coral, as different wavelengths have different growth benefits for different species.

  • Think about how often you need to access your aquarium for maintenance, cleaning and other routine tasks. Consider how a mounted or hanging lighting system might impact on these actions and the best way to position the system around this.

What to do

  • Play around with your colors.

    The full spectrum of colors offered by many LED lighting systems are not just for show, despite creating some very attractive tank effects.
    Using the appropriate wavelength of light for a particular growth stage of a coral’s life can increase growth considerably.
    Either way, whether you want an attractive looking tank or improved growth amongst your coral organisms, you should experiment with different combinations of LED light and research into tried and tested methods.

  • Utilize your LED dimmers.

    LED lights traditionally come with dimmer switches, which allow you to tailor the exact level of brightness within your aquarium.
    They also allow you to blend different colors together, which can create different effects, promote the growth of numerous lifeforms simultaneously, and also extend LED lifespan by spreading the load across multiple LEDs.
    Finally, they also bring out the color in your corals and fish.

  • Provide ventilation for lighting.

    As cooling fans and heat sinks on LED lighting systems are typically mounted on the reverse or sides of a unit, your lighting system won’t transfer heat directly into your tank’s water.
    That said, excessive heat build-up can damage LED components, leading to a reduced longevity.
    There are ways of preventing this build-up from becoming a problem, such as using a hanging light setup, avoiding canopies, or incorporating additional fans in smaller spaces where ventilation is poorer.

  • Research what colors benefit your fish.

    It’s not just corals that can benefit from LED lighting.
    Some species of fish prefer varied levels of brightness and specific wavelengths of light.
    You may learn which of your fish prefer which types of light from experimentation within your aquarium, once you’ve set up your LED lights.

  • Maximize the beauty of your corals.

    Coral is a naturally-stunning organism with a wide spectrum of colors.
    Some LED lights bring out these colors better than others and really make them pop.
    To achieve the most impressive appearance in your marine aquarium, look for LED lights in the ‘actinic royal blue’ spectrum.
    For soft corals, often called ‘softies’ in aquarist circles, combine some magenta LEDs using a dimmer to control the combination of the two spectrums.

  • Set up your own cycles.

    Depending upon the product that you’ve chosen and the functionality that it supports, you may well be able to set up your own lighting cycles.
    Some products support pre-set cycling, whereas others will allow you to tailor your own using the built-in dimmers.
    Common choices include ‘day’ and ‘night’, or ‘daylight’ and ‘moonlight’, simulating high-intensity and low-intensity lighting cycles, respectively.

What to avoid

  • Don’t expose your LEDs to water.

    Despite your LEDs being designed to sit in close proximity to the water within your aquarium, they are still not designed to get wet or be submerged.
    Such exposure to water over time could lead to corrosion of vital components, as well as electrical failures and short circuiting.

  • Avoid damaging your corals.

    Different models of LED lights can generate varying levels of brightness, though any good system will have a means of adjusting the light level used (usually referred to as a dimmer switch).
    With very bright LEDs, there’s a danger of causing burn damage to your corals if you move from a low-light environment directly to using a very high level of brightness.
    You should always start with a lower intensity setting, scaling up the brightness level gradually.

  • Don’t allow a build-up of salt or mineral deposits.

    The downside to salt water aquariums is that you can end up generating a lot of salt and mineral deposits over the course of the tank’s lifespan.
    If not regularly cleaned from the tank, they can become a nuisance.
    However, if not cleaned from the lighting system, they can cause corrosion, directly reducing the lifespan of the LEDs and other integral components.

  • Don’t overload your lighting mounts.

    Whichever way you choose to set up your lighting system, you should ensure that the load isn’t too heavy on its support structure.
    If hanging the LEDs above your aquarium, the last thing you want is for them to fall into your tank, simultaneously killing your fish and damaging your lighting system.
    Similarly, too much load on a rim-mounted lighting system could put stress and strain on your tank’s glass panels.

TIPS to keep healthy corals

Once you've established your corals within your aquarium and have set up an LED lighting system, you can generally maintain healthy corals by ensuring that the water within the tank stays at or around the following parameters:

  • Alkalinity levels around 2.1 to 2.5 meq/l

  • Water temperature at approximately 76 to 82 degrees Fahrenheit

  • Calcium levels around 400 to 500 ppm

  • Magnesium levels around 1200 to 1400 ppm

  • Ammonia, nitrates and nitrites, and phosphate levels at zero

Hipargero Touch Control 30w CREE Nano LED Aquarium Light

The Hipargero Touch Control Light is specially designed for marine life aquarium tanks, with LEDs that are tailored towards the growth of almost any type of corals that you would find in saltwater aquariums.
What's more, the LED channels are dimmable and feature blue and white spectrum lighting; these LEDs are touch-controlled, with variable intensity that can be changed with a single touch.
Keeping the whole unit cool is simple with built-in intelligent fans that tailor their operational speed to varying temperatures, ensuring that the LEDs are kept cool.
Regardless of how fast the fans are running, they're still incredibly quiet.

What we like

  • Specially designed to propagate the growth of marine corals
  • Touch-controlled LEDs can be adjusted in their intensity
  • Reactive fans control temperature in a dynamic way
  • Remembers the previous setting when powered down and back on

What we don't like

  • Some users reported it doesn’t come with setup instructions
  • Can be difficult to mount onto aquariums that have a rim
  • Though specially designed for coral growth, it’s not as good for growth of plant life

If you like intuitive, user-friendly experiences in your products, then the Hipargero light is ideal for you with its touch-controlled LED intensity settings.
As these are remembered when the light is powered down, you won’t have to deal with a lengthy setup process whenever you switch them on, too.
Finally, the intelligent fan cooling system is a truly innovative feature, responding to temperature fluctuations by adjusting fan speed to cool more quickly where required.
This is a feature that isn’t commonly seen in other lighting products.

LED Reef Aquarium Lights for Saltwater Coral Fish Tank

This LED aquarium lighting mounts directly onto the top of your tank using adjustable support legs.
Although this makes it very easy to install, it also reduces access to the tank when you need to perform cleaning or maintenance, when compared to products with separate stands or mounts that sit away from the tank.
However, this simplistic design means that there’s scope to expand the product with additional LEDs so it could realistically serve multiple aquariums of varied sizes if swapped around.
Overall, the LED intensity is reported as being weaker than some competing products, however the price is also more affordable as a direct trade-off.

What we like

  • Easy access ‘On’/’Off’ switch removes the need to unplug AC power to turn off
  • For larger aquariums, expansion slots allow for the insertion of more LEDs
  • Blue and white spectrum LEDs can be controlled independently of one another

What we don't like

  • Mounts directly across the top of the tank, reducing access to the tank if needed
  • Focused LEDs: this unit doesn’t have the best dispersion or coverage

If you’re the type of aquarist running multiple aquariums as part of a larger setup, then this could well be the lighting system for you.
The ability to expand it with additional LED ports means that you needn’t buy an entirely new unit if moving to a larger tank.
However, if you’re the kind of person who needs constant access to your tank, be it for cleaning or the regular introduction of new species to your aquarium, then the mounting system could become a hindrance to you.

Ledgle Led Aquarium Light Dimmable 300W

As is the case for hobbyists into hydroponics and grow-lighting, having the right LED lighting can speed up the growth of your plant life.
With this product, a full spectrum of LED lighting specially targets all the growth stages of coral and plant life, optimizing their growth.
During this time, you have complete control over the intensity of the LEDs through two adjustable dimmer switches, and heat build-up is countered by 3 built-in fans that disperse heat through the rear of the unit.
This prevents any rise in water temperature that could compromise the health of your tank’s inhabitants.

What we like

  • Built-in fans prevent build-up of heat from lighting
  • Two dimmers provide 100% control of light intensity
  • Full spectrum LEDs provide lighting tailored to varying growth stages of coral

What we don't like

  • Multiple units required for full coverage of larger tanks
  • Red LEDs are less common than blue and white in the aquarist world

For larger tanks with widespread coral growth, this is perhaps not the first choice, as a 90-degree lens design focuses the light and reduced tank coverage.
However, this does result in deep water penetration, so this unit would be beneficial for cylindrical or bow-fronted tanks in particular.
The inclusion of red LEDs is less common in aquarium lighting as opposed to colors like blue and white, but they can be useful for growing plant life and bringing out the colors in certain species of fish.

MarsAqua Dimmable 165W LED Aquarium Light

MarsAqua are known for their high-quality LED lights, though you’ll typically pay a little more than the average for the quality.
Even on the lowest intensity settings, the Dimmable 165W LED Aquarium Light is capable of penetrating deep into tank water, reaching corals at varying heights, and several units can easily be chained together, creating a setup big enough to cover even the largest capacity of aquariums.
Though the light is perfect for creating strong coral growth, it should be avoided with freshwater aquariums; in such setups, you’ll more likely suffer problems with algae growth, so keep these for the saltwater aquarium tanks.

What we like

  • The light mounting kit is very easy to install
  • Multiple units can be daisy chained together with ease
  • LED light penetrates deep into tanks with ease, even on lowest settings

What we don't like

  • Fans can often run louder than other lighting units
  • At the higher end of the budget range as far as LED lighting goes

With both good light coverage and deep water penetration, the MarsAqua works well with aquariums of a variety of depths and sizes, though it’s best to keep this unit for salt water aquariums rather than fresh water tanks.
The LEDs used in this lighting unit are extremely powerful and produce an intense brightness, though you’ll typically pay a little more than with other competing products.
The cooling system also tends to run slightly louder than others, but this is generally expected given the intensity of the LEDs.

- 5-
Phlizon 2017 Newest Extremely Long Aquarium LED Light

The Phlizon 2017 LED light can be purchased in two assorted sizes, with one being suited to shorter, fatter tanks, such as bow-fronted models, and the other suited to longer, thinner aquariums.
Both dimensions of tank are built from high-quality materials and provide real value for money.

The difference in brightness at the lesser and greater end of the variable setting is large, though it’s unlikely you’ll ever need to run the light on its maximum brightness as a result.
Aside from this excessive brightness, the only other fault to find with this model is in its temperature cooling system; just 2 fans are built into this model, and they can be quite loud when running.

What we like

  • Day and Night modes supported through two separate dimmer switches
  • Large variation in brightness possible when dimmer switches are used
  • Full spectrum of light supported; not only red, white and blue, but green and purple, too

What we don't like

  • Only features 2 cooling fans, even on the longer model, whereas many similar models use 3
  • LEDs can be too bright and less aesthetically pleasing if run on their full setting

Depending upon the length and width of your tank, there are two different size Phlizon models to consider, but both are built to the same high standard.
Setting up separate light cycles will not be a problem with the separate dimmer switches, and the sheer brightness of the included LEDs will easily allow you to create intense day and low-intensity night cycles for your tank’s inhabitants.
You may be at risk of burning your coral if you run these LEDs too high, so ensure that you gradually increase intensity over time if opting for these lights.

- 6-
Lightimetunnel 165W Dimmable LED Aquarium

The Lightimetunnel LED Lights employ the use of 3-watt LEDs arranged in a formation of 55 bulbs.
These consist of a full spectrum of colors, including 660nm red, 460nm blue, 430nm purple, 450nm royal blue, 520nm green, and warm and cool white lights.
Two separate sets of controls mounted on the rear of the unit allow direct control over half of the LEDs each.

Through the use of these controls and the variety in the LEDs themselves, it is possible to simulate daytime and moonlight environments.
Finally, it’s worth a mention that the design incorporates 45mil Bridgelux white and 45mil Epistar blue LED diodes, which output 30% more light than competing models.

What we like

  • Compatible with wall-mounted brackets for greater control over your lighting arrangement
  • LEDs divided into two halves; sets of controls on the rear allow independent adjustment
  • Supplied with 2 power cords and hanging attachments for setup

What we don't like

  • Mounting mechanism doesn’t allow for a great deal of vertical adjustment
  • Very sensitive dials can make for difficult fine-tuning of brightness settings
  • Product could benefit from a built-in timer for different light phases

With a full spectrum of LED lighting possible, you can use this lighting system to tailor your aquarium’s lighting to specific stages of your coral’s growth.
The use of high-quality components also means that you can expect a 30% greater output than many other LEDs on the market, split into two arrays that can be independently controlled with separate dimmer switches.
However, if you want timed cycles of varying intensity, then you’re going to have to pick up a timer separately as one is not included with this product.

Euphotica LED Aquarium Light Fixture for Saltwater/Coral Tanks

With two power cords, easy to understand instructions and a supplied hanging kit, the Euphotica Dimmable Light Fixture is easy to set up straight out of the box.
However, if you’re not keen on hanging your lighting unit directly above the aquarium, you may have more difficulty with this product.

The light includes an LCD touchscreen that makes it incredibly easy to adjust and program your preferred settings, even if you do have to reprogram them.

What we like

  • A hanging kit is included with the product
  • Includes a programmable LCD touchscreen
  • Instructions included with these fixtures are easy to follow and understand

What we don't like

  • Focused light reduces the coverage offered by this unit on larger tanks
  • It is designed to be hung above your tank; doesn’t support other mounting methods

This product could certainly benefit from having an internal memory system for remembering past settings and cycles, as well as a more varied method of securing the lights.
However, a hanging kit is included with the system, plus the setup is clearly explained through detailed, easy to understand instructions.
What’s more, this lighting unit includes a programmable LCD touchscreen.
If your settings are lost, then they are at least easy to set back up using this unique feature.

Aqua Air 20W - Smart LED Aquarium Lighting

The Aqua Air 20W LED Lighting is an ideal product for the entry-level hobbyist or aquarist with only a small aquarium tank.
Built-in mounts reduce the need for any cumbersome hanging system, though do limit the options available for setting up the lights.
Still, this ensures that the tank is always easily accessible for any cleaning, maintenance, or access to other equipment such as filtration media.
Despite its small stature and cheap price tag, there are a range of pre-set and customizable settings, including some that are included for aesthetic purposes, such as the ‘thunderstorm’ setting.

What we like

  • Cheap in comparison to many other models listed here
  • A range of pre-set and controllable setting options
  • Innovative mounting system allows easy access to tank for cleaning and maintenance

What we don't like

  • Fewer LEDs than competing products and not full spectrum
  • Can’t be detached from its mounts and suspended above the tank
  • Aluminum design is less aesthetically pleasing when paired with a dark or black tank

This product is quite unique in comparison to the other LED lights on our list, as it uses a tank-mounted pair of adjustable legs to suspend itself above the tank.
Constructed from aluminum, it is also corrosion resistant. Ideal for entry-level aquarists with small aquariums, this unit comes in very cheap.
Unfortunately, you do lose some functionality by paying less; alternative options for hanging or supporting this lighting unit are non-existent and there are fewer LEDs, meaning that a full spectrum of light is not supported.

- 10-
Aquarium LED Light, ICOCO 55x3W 165W LED Dimmable

This LED lighting unit has a very low level of power consumption compared to similar products in the industry.
That said, the light does not skimp in other areas; the design is high-quality, constructed from aluminum, which offers greater corrosion resistance than plastic.
Despite this benefit, the product still needs to be kept out of direct contact with water, as the LEDs are not waterproof by any means.
Speaking of LEDs, this product has a full spectrum of wavelengths, including blue, white, red and green, giving you full control over the growth of your corals.

What we like

  • Low power consumption; environmentally-friendly
  • Aluminum frame is more resistant to salt water corrosion
  • Full spectrum of light supports both coral and plant life growth

What we don't like

  • Not waterproof and should be kept a safe distance away
  • Day and night lights are controlled by two separate plugs as opposed to one

The ICOCO light is a good-quality light overall, though lacking in any special functionality to set it apart from competitor products, particularly given that it commands an average to high price tag.
However, it makes the list as does have several plus points, including an aluminium frame that is resistant to salt water corrosion, a full spectrum of light wavelengths for targeted growth of coral and plant life, and what’s more, it is environmentally friendly owing to its very low power consumption.


If you’ve chosen to start a saltwater aquarium, then you may well have chosen to populate your tank with corals.
These organisms not only need light, but can benefit from certain wavelengths, too.
Through the utilization of LED lighting, and by choosing the correct intensity and color of LEDs used, you can speed up the growth cycle of your corals and achieve a bigger, healthier size.
Once your corals are established, then it’s simply a case of maintaining homeostasis within your tank’s water, adhering to the chemical balances outlined above.

Always consider how a lighting system will fit within the constraints of your aquarium setup, including how it will be hung or positioned, the size and number of LEDs required for your capacity of tank, and the coverage or spread offered by the lighting system.
When it comes to value for money and propagating coral growth, choosing a full spectrum product is generally the best option.
