The first thing that we noticed about this item is the beautiful square-shaped tank that is made of glass and curved at the corners. This gives you a better view of the fish in the tank and enables you to notice if there’s some abnormality immediately. 

The back panel is also made of clear glass, which makes it convenient to add a refugium. Another thing to note is the glass quality. Although it is impossible to ensure zero scratches on the glass, any sort of wear and tear will be at a minimum with this product.

Moreover, to amplify the beauty and increase the tank’s visibility, there is an in-built hood with an LED light installed in it. It is perfect for corals and mostly all other types of reed species as it comes with actinic moonlight and a timer. The customizable filters allow you to raise a range of SPS corals too.  

What Could’ve Been Better?

There is hardly any complaint that we have with how well this item performs. However, we noticed that it was a little loud. The noise is specifically audible during the night when the room falls silent. We recommend that you do not keep the tank in your bedroom. 

  • Attractive design
  • See-through glass on all sides
  • Suitable for a range of corals
  • Easy to clean
  • Makes a little noise

It is highly efficient in creating the most suitable environment for marine life to thrive. With this device, you will face no trouble feeding the fish, and raising them becomes super convenient.

Why Did We Like It?

The LED light in the tank is quite notable as it adds to its beauty and highlights the marine life in it. However, even if you keep the light switched on throughout the day, you need not worry about wasting electricity. The LEDs are highly energy-efficient and thus are pretty cost-effective. They are mounted in such a manner that the light gets distributed equally in all corners of the tank. 

Additionally, this tank is easy to use. Unlike many tanks where you could face difficulty removing the canopy to feed the fish, this one is relatively simpler. The glass canopy slides smoothly over to the rear end of the tank through which you can feed the fish and check the water condition. 

Furthermore, maintaining the best water quality inside the tank is crucial to ensure thriving marine life. And this product helps you do that in the most efficient fashion. The adjustable filter pump in this device adds to its overall convenience.  

What Could’ve Been Better?

After using it for a few months, there’s one downside to this product that we noticed. Cleaning seems to be quite a challenging task. The placement of the filter motor is such that it gets a little difficult to access. So, we suggest that you keep this in mind on your cleaning day and reserve some extra time for this. 

  • Premium-quality performance
  • Stylish design
  • Easy to use
  • Helps to maintain good water quality
  • Cleaning is time-consuming
Tank Capacity: 3 gallons | Lighting System: LED lighting | Filtration System: 3-stage filtration | Tank Material: Glass | Additional Features: Sleek, contemporary design

Why Did We Like It?

One thing we can say is that this tank is an excellent choice for hobbyists, beginners, and professionals alike. Simply put, it is so easy to use that irrespective of your level of expertise in working with aquariums, you will not face any difficulty in maintaining this one. 

Moreover, the LEDs that are attached to the tank are pretty versatile and come with customizable functions. Depending on the time of the day, you can either shift it to white or yellow light, based on your preference. 

Plus, the filtration system of this tank is quite noteworthy. It is not a single-stage filter. Instead, it is a 3-stage filtration process that provides the most potent combination of biological, mechanical, and chemical filtration for the aquatic lives in the tank.  

What Could’ve Been Better?

The performance of this product is undoubtedly top-notch. However, there’s one thing that calls for improvement. The connecting plug is a little short, and therefore you need to put your tank very close to the power source. Or you can make use of an extension cord to tackle the problem. 

  • Easy for everyone to use
  • LEDs add beauty to the tank
  • Water filtration is incredible
  • Simple cleaning process
  • Cord is too short
Tank Capacity: 20 gallons | Lighting System: LED lighting | Filtration System: Internal filtration | Tank Material: Acrylic | Additional Features: Includes GloFish special effects

Why Did We Like It?

When it comes to looks, this one will surely grab your attention. The manufacturers have spent a good deal of time and effort in perfecting the design. And now, this stands as one of the most attractive choices under the 20-gallon category. It is mainly the honeycomb design pattern that makes it stand out amongst its contemporaries. 

Additionally, if you are thinking of raising corals, this tank can be an ideal fit. The hooded LED lights are highly efficient and suitable to help the corals thrive. The actinic moonlight setting further helps in the process. 

On top of that, the kit is quite well stocked and adjustable if you want to add other products like protein skimmers and water heaters to help the aquatic life survive better. You do not have to buy any tools or instruments separately to ensure this.  

What Could’ve Been Better?

Once again, we did not find any significant downside to this. However, after a few weeks of using it, we noticed that the rear end’s filter compartment is a little small. And in case you have big hands, you might find it a little hard to reach. To avoid minor injuries, we suggest that you wear gloves whenever maintenance is required.

  • Unique honeycomb design
  • Well stocked kit
  • Can be used with other aquarium products
  • Great for raising corals

The 20-gallon reef tank is ideal for those who want an aquarium to accentuate the décor but does not want it to take up much space. This size is perfect for accommodating multiple fish without occupying too much space in the room. 

Moving on, setting up this reef tank is a no-brainer. The user manual is extremely well laid out and takes you to step by step through the process of setting it up. So, even if you are installing it for the first time, you will face no difficulty doing it. 

Plus, the kit is exceptionally well-stocked. Apart from the tank, there’s one UL heater, filter, energy-saving, and color-changing LEDs, and 2 Wonderland plant multipacks included in the package. You will not have to incur any extra expenses to buy any essential tools.  

What Could’ve Been Better?

Even though the package includes a thermometer that helps you keep a check on the water temperature, there’s a small glitch. It is a little too big and tends to stick out of the tank. We suggest that you be careful while walking around it. 

  • Exceptionally well-designed
  • Compact size
  • Includes detailed user instruction
  • Comes with all essential accessories
  • Size of the thermometer is too big

It comes with an excellent filtration system that keeps the water in the tank speckles and maintains the best condition inside. The filtration system is well-hidden from view and placed behind the tank to not ruin its aesthetic value. 

Plus, they offer incredible customer support. You can reach out to them 24×7 in case there’s some maintenance issue to resolve or if you need help setting it up.  

What Could’ve Been Better?

Powering this item might seem a little challenging to some. We noticed that the cord is short, and you have to ensure that there is a charging point close to the tank. Otherwise, you can use an extension cord to power it easily. Even the USB that is included in the pack comes without an adapter, you might have to purchase it separately.

  • Designed exceptionally well
  • Highly efficient filtration system
  • Responsive customer service
  • Easy set-up process

Moreover, you do not need any added accessories to set up this item. It requires no special stand, and the cushioned bottom of the tank prevents it from sliding off. Place it on any table that you fancy, and you are good to go!

And the best thing about this is the 3D background décor. It is stuck to the back of the tank with water-proof glue, and it makes it look like a dreamy underwater world. This provides an excellent playground for small fish and shrimp and brightens the aquarium, making it look more lively. 

What Could’ve Been Better?

While using this, there’s one thing that you need to keep in mind. The filtration system is quite strong and is not very suitable for small betta fish. We recommend that you turn down the power of the system or avoid putting tiny fish in the tank. 

  • Maintenance is simple and cost-effective
  • Brilliant design
  • Cleaning the tank is quite easy
  • Simple installation process

Feeding the fish will no longer be a hassle with this product. There’s no need to slide off the heavy glass or turn off the tank when you put the granules. This item comes with a hinged lid that gives you easy access. The feed hole is covered with a silicone plug, and you do not have to worry about the water evaporating fast. 

Plus, the design of this tank is such that the waterline is not visible. The circular shape of the aquarium conceals the water line completely. Similarly, the airline is placed at the bottom of the tank and discreetly goes to the back of the aquarium. 

Additionally, the simplicity involved in operating this item is incredible. It has non-slip feet at the bottom that enable you to place the tank anywhere you like without fearing that it might slip.  

What Could’ve Been Better?

The only downside that we noticed about this item is that sometimes it gets a little challenging to work with a magnetic lid. If you decide to put more accessories in the tank, such as submersible water heaters, the chances of the lid remaining open are rather high. 

  • Easy to use
  • Cleaning is quite convenient
  • Water does not evaporate easily
  • Waterlines and airlines are well concealed
  • Big accessories may not fit in

Additionally, the filtration system in this tank is entirely customizable. So, depending on the kind of fish or corals that you want to keep, go ahead and set the system’s power accordingly. This would help you prevent any form of probable accidents that might be fatal to the fish.  

What Could’ve Been Better?

The only downside to this product is that the protein skimmer included in the pack is of poor quality. Indeed, the kit is well stocked; we couldn’t help but feel that the quality of the skimmer could have been better.

Buying Guide For The Best Nano Reef Tank

Now that you have read about the top 10 nano reef tanks, were you able to make a choice? Well, we know it is not so simple. Just knowing about the products’ features is not enough to help you make the best call. 

There are a few other factors that need to be taken into consideration. And in this section, we are discussing them in detail to help you make an informed decision. So, let’s check them out!

  1. Tank Shape And Size

This is one of the most important considerations before you decide on an option. The size of the tank directly affects the health of your fish. If you already know what kind of fish or coral you want to keep, it is better to select a tank accordingly. 

Note that a bigger tank is better if you want to house more fish and is highly suitable for corals.

The shape of the reef tank is also quite crucial. Mostly, the common types either come in squares or cubes. We have noticed that people tend to opt mainly for cube-shaped ones since they look more attractive. 

Thus, we suggest that you can go for a large nano tank unless space is an issue and keep adding new fish as and when you like. 

  1. Lights

Lights add beauty to the reef tanks, and you should always be careful on this front. Not just that, in case you are housing corals in your tank, their growth and color is highly dependent on the kind of light that’s present in the tank. 

If you are keeping saltwater corals, you will need a high-color temperature warm LED lighting system. And in case you are going for freshwater marine life, you will require a low-temperature LED to support their growth.

In the list mentioned above, you will find options that come with adjustable LED color settings. You do not have to stick to just white or yellow; you can play with other colors, like blue and red. However, always keep in mind to go for energy-saving options to make sure that the power consumption does not hit the roof.
