If you want a small tabletop aquarium, this tank kit is an excellent option for you to consider. It has dimensions of just 24.5 x 11.8 x 16.3 inches, so this tank can fit into nearly any space and liven up the surroundings. Also, being on the smaller end with five gallons of capacity, it is pretty easy to maintain and suitable for keeping small fish or coral.

While the smaller size is great for mini setups in cramped spaces, it does limit your options.

In particular, this tank will not accommodate larger schools of fish and can only fit small decor items. So, if you plan on building a full-fledged setup, a larger alternative might be better for you to consider.

Installation and Maintenance

While many saltwater aquarium kits are pretty tricky to install, that’s not the case with the Fluval Evo V Marine Aquarium Kit. Installation starts with separating all the individual components, after which you should clean them with a wet cloth. After this, set up the filter media, lighting, and integrated parts into their respective locations, lock the lighting system in place, and your tank is ready!

Maintenance is also straightforward with this aquarium kit. Apart from weekly 20 percent water changes, you only need to replace the filter media once a month, and the tank will be clean and clear for your pets.

Also, as the filter media comes right out of the box and is easily available online, you won’t have to worry about scoring stores or the internet for it. Thanks to this, even if you are a beginner, the Evo 5 is a great option to choose.


One of the most striking features of this marine aquarium kit is the tank itself. With an eye-catching honeycomb cuboid design, this tank can liven up any setup and bring your coral to life.

As the three sides are transparent, this tank has excellent visibility and is suitable for 5-gallon saltwater tank setups to show off your decor. 

While the design adds to the look and feel, it makes this tank quite difficult to use with external devices. While most accessories and parts are included, if you plan on utilizing an external filter or pump, it might require some tedious work to get everything in place.

For example, if you plan on using a separate air pump or action decoration, this will have to be kept outside the tank and connected externally.


The Fluval Evo 5 kit offers an inbuilt filtration system that is great if you plan on setting up a 5-gallon reef tank. The powerful system utilizes three unique stages of filtration for an all-around water cleaning.

The system uses mechanical filtration to clear out large debris, biological filtration for bio-waste, and chemical filtration to remove ammonia and toxic substances from your water.

Thanks to its triple-faceted filtration system, the tank provides a suitable environment for fish and coral to thrive.

Included Parts/Accessories

Let’s go over some of the included parts provided in the Fluval Evo 5 aquarium kit:

LED Lighting

The Fluval Evo 5 has a built-in LED lighting system that boosts the utility and appeal of this tank. The system is bright enough to light up the whole tank and is excellent for viewing in the dark.

Along with its aesthetic benefits, this lighting system also boosts coral growth. It is undoubtedly the perfect addition to a reef tank. This light will make tank management a lot easier with an easy on/off switch accessible from the tank’s roof!

What’s interesting is that you can set a day/night timer to the lighting system so that your aquarium LEDs will mimic actual sunset and sunrise times. 

Low Voltage Transformer

This 5-gallon saltwater aquarium kit includes a low voltage transformer that makes it an excellent choice for rural and urban areas. Even if your locality is prone to power or voltage cuts, this device will ensure that the tank keeps functioning properly and your pets and plants remain safe.


The Fluval Marine Kit also comes with a custom tank roof/canopy that is very convenient. It fits on perfectly and is quite sturdy so that you can place light objects on top of the tank without any worry. Also, with its sleek and transparent form factor, this roof highly adds to the overall look of the tank.

An added benefit of this canopy is that it has built-in cutouts that match the lighting system above this tank. You get a seamless setup that blends in and works perfectly together, thanks to this.

Multiple Filter Media

We like this tank kit because all the required filter media is available right out of the box. So, you’ll be getting a Fluval foam filter block, an activated carbon insert, and a BioMax insert for mechanical, chemical, and biological filtration.

So, all you have to do is place them in the filtration system, and you won’t have to worry about replacements for one month.

An added advantage of this kit is that Fluval filter media is readily available online. So, once it is time for maintenance and replacements, you can easily order the media and have it delivered to your doorstep.


Is the Fluval Evo 5 Filtration System Good, or Should I Add an External Filter?

The three-stage filtration system offered by the Fluval Evo 5 is an excellent setup that can deal with mechanical, chemical, and biological filtration on its own without requiring the help of an external filter. It is a perfect solution for beginners and people on a tight budget. 

Can You Use Fluval Evo for Freshwater?

Fluval Evo 5 marine aquarium kit reviewYes, you can use the Fluval Evo 5 for freshwater applications. However, keep in mind that the kit is suited for a saltwater/reef tank and may not work if used with fresh water.

The lighting system is built to promote coral growth, and the filtration system is designed for use in saltwater environments.

Do Saltwater Aquariums Smell?

No, as long as your saltwater tank is filtered properly and has good water quality, it should not smell. If your tank does have a ‘bad’ or pungent smell, it indicates bad water quality. In such cases, upgrading your filtration system or checking for leaks or cracks in the existing system is suggested.

How Many Corals Can I Add at Once?

Adding a maximum of 40 corals at once should be fine, but the exact number depends on your tank size and shape. As corals have a low bioload and don’t create much waste, you can easily add lots of them simultaneously without any issues.

However, we advise you not to add all 40 at once and spread it out within a few days to monitor their health and adjust to your tank.

Can You Have a Lot of Corals in a Tank?

Yes, you can add a lot of corals to your tank. While corals are known to have a low bioload compared to other animals, there is always a limit to the number of corals you can keep in a confined space. 

Should You Add Coral or Fish First?

It is best to add the fish to your tank before adding the coral. To make sure that your pets have time to acclimate to the environment, it would be best to leave them alone in your tank for about a week before you start adding coral.

So, if you are planning on keeping a small variety of fish or coral, Fluval Evo 5 might suit you best. Also, with a unique honeycomb design, it is sure to add to the aesthetic appeal of any space you put this tank in.

As it is only five gallons in capacity, you will be limited by space and might be better off looking for a larger alternative such as the Fluval Evo 13.5.

We hope this review helped you get an in-depth understanding of the Fluval Evo 5 and whether it is the right choice for you.
