If you are newly decorating your home, you might stumble upon the idea of keeping an aquarium. But as we all know, there are a lot of factors that you need to consider before buying one.

An aquarium can beautify the look of your home. The beautiful plants and the fishes in the tank will make a pretty picture for everyone to admire. However, to keep your favorite marine life and aquatic plants, you need a proper tank.

The tank you choose will serve an essential purpose by providing a proper place for fishes and corals to live in. It should serve as a natural or realistic environment for your pet fish.

This is because choosing the wrong type of tank can harm marine life and eventually kill it. The size of your aquarium will ultimately influence your choices regarding aquatic plants and fishes.

The Fluval Edge is a nano aquarium. A nano-sized tank is usually smaller than its large counterparts. For instance, this tank holds only 12 gallons of water.

In this Fluval Edge review, we will dive into the details of the product, breaking it down to pros and cons. Based on this review alone, you can decide whether or not to purchase the aquarium.

Things to Consider Before Buying

An aquarium requires a lot of accessories before making it livable for the fish. People who want to keep different types of fish and plants also need various kinds of things to keep them comfortable in the tank.


The size of the tank will determine the amount of fish that you can keep. Also, the aquarium size depends on its allocation. A large container can sometimes be challenging to install in your home.

For instance, the product we are reviewing in this article is comparatively smaller. Let us have a look:

·      Limited Marine Life

If you are planning to keep a lot of fishes of all sizes as well as large aquatic plants in your aquarium, then this product is not for you. The compact size of this tank will only allow you to keep a small number of fish and plants.

For hardcore aquarists, this can be a tough choice because fishes like Neon Tetra, Longfin Zebra Danio, etc. are large creatures which can only live and thrive in a big aquarium.

Moreover, the small size of this tank also limits the choice for large aquatic plants. For instance, plants such as Amazon Swords and Java Moss are known to grow pretty fast in the tank, so they are only suitable for large aquariums.

However, in the Fluval Edge tank, small fishes like guppies, bettas, and red cherry shrimps can be kept, and it is also an excellent option for a beginner.

Presenting The Fluval Edge 12 Gallon Aquarium

The 12-gallon aquarium weighs around 34.5 pounds and is a more extended version of the 6-gallon tank. It features 42 LED lights, which is sufficient enough to lighten up the whole aquarium.

Out of the 21 LEDs, there are 39 white lights and three blue lights. The blue lights can be used during the night to imitate moonlight. You can also switch the lights from blue to white throughout the day.

Furthermore, there are three settings, deep blue, on and off, and daytime so you can choose the one you like. It looks aesthetic because you can see everything correctly through the clear glass.

The aquarium is available in white and black. It has a powerful filtration system. The Edge Filter incorporates Cycleguard as well as Nutrafin Aquaplus and Nutrafin Cycle for cleaning the water efficiently.

Its filtration method is so effective that you only need to clean it every three months.  The tank also includes perforated cover. However, the top aquarium in the market right now is the Marineland Portrait Aquarium.

The Marineland aquarium has moonlight and daylight settings, which makes it different than the other products. The white LEDs create a shimmering effect in the water, whereas the blue LEDs provide an enchanted moonlight glow.


  • Stylish and modern design
  • Powerful filtration system
  • 42 LEDs including three blue lights and 39 white lights
  • Removable perforated cover for maintaining filter and the tank


  • Compact size limits fish choices
  • The access at the top is quite limited

Fluval Edge Review: Features and Benefits

·      Elegant Tank

The selling point of this product is the unique tank itself. It is different than all other tanks in the market. Although the tank can be filled to the brim, if you keep any bettas in it, you have to leave a little space at the top for the fish to breathe appropriately.

The tank’s glass is shiny and crystal clear. Its 360 views will allow you to see every inch of the tank, and this will come in handy, especially when you’re cleaning it. Moreover, its small size will enable you to fit the tank anywhere in your home.

You might have a little problem while maintaining the tank because it has a small opening. So you can use a magnetic glass and gravel vacuum to scrub the tank thoroughly.

·      Efficient Filtration System

This tank comes with an effective filtration method. It includes a standard mechanical, chemical, and biological media used for removing debris, chemicals, and bacteria, respectively.

Along with this, you will get the Nutrafin Cycle, which will produce good bacteria. The bacteria will effectively rid your tank from diseases and illnesses. Not only is the system robust, but it is also hidden from view.

It conveniently remains concealed from the view, so you don’t need to worry about it blocking your tank. The filter might be a little loud and noisy, but this only happens for a few days.

After that, the filter will operate quite silently. The system also has space inside of it, so you can even add accessories like water cleaning pads. Furthermore, you can adjust the speed of water with power settings.
