Fluval Chi Aquarium Features

Let’s take a closer look at all the features that the Fluval Chi fish tank has.


First of all, the first thing to know about the Fluval Chi Fish Tank is that it is a small tank, a 19 or 25 liter nano tank. This makes it more than ideal for a medium sized fish or a few smaller fish.

It is not a good option if you do not have much experience with aquariums since in smaller environments it is more difficult to maintain the balance of the parameters.

The Fluval Chi fish tank is square and has a size of 25.4 x 30.5 x 25.4 cm (19 l) and 25.4 x 45.7 x 25.4 cm (25 l). It can easily fit on a shelf, on a nightstand, or on an office desk as well.


Another important point to keep in mind is that this tank is made of glass. Yes, some people prefer acrylic because it has a higher level of impact resistance, but glass looks much better in our opinion.

Although glass may not be as strong as acrylic, it sure looks good, plus the Fluval Chi Tank is built to last. As long as you don’t drop this fish tank from a height, it’ll be fine.


One of the best things about the Fluval Chi aquarium is that it comes with a 3-stage filtration system. The filter included here is more than powerful and efficient enough to keep the water inside the tank clean and crystal clear.

It has enough filtration capacity to process the tank water several times per hour, achieving optimal cleaning. The filter deals with the three main types of filtration: mechanical, biological and chemical.

The mechanical filtration aspect removes all kinds of solid waste from the water. Biological filtration helps maintain a healthy bacteria population to remove ammonia, nitrites and nitrates. Chemical filtration is excellent at removing any toxins, odors, and discoloration from the water.

The filter included in the Fluval Chi is specially designed to prevent water bypass. In other words, every drop of water comes into contact with all 3 filtration mechanisms for great efficiency.

Now what is really cool and unique about the Fluval Chi fish tank filtration system is that it pulls the water out of the bottom of the tank and filters it in an upward motion. It exits out the top of the tank through the stone basket, creating a serene and calming waterfall effect.

This is a good option if you like the sound of water. On the other hand, the filter has a 180-degree rotating filter head, which is great because it provides easy access to the inside of the filter for easy cleaning and media change.

Plant and media basket

Another cool feature of the Fluval Chi Aquarium is the stone basket at the top of the tank. We’ve already talked about how the water flows out of it to create a waterfall effect.

However, what we did not mention is that you can replace the stones with whatever you want, rocks or even some kind of decoration. It may not have a lot of functionality, but it certainly provides an attractive look.

At the same time, the inside of the tank has a plant basket. This plant basket is removable so you can easily take care of the plant when the time comes. Simply lift the basket out of the tank to perform plant maintenance.

You can also change the plant that is included and replace it with a plant of your choice. It’s a cool feature that allows you to add a fake or potted plant with minimal effort.


The Fluval Chi fish tank comes with a full LED lighting system, something virtually every aquarium needs to have.

This particular aquarium comes with a 12-LED submersible lighting system. The lights are encased in a waterproof housing to ensure no water damage.

Having submerged lights is a neat feature that not many aquariums have. It creates a really cool look on its own, helps plants grow, and helps light up the tank.

There is also a second set of upward facing lights directed at the water coming out of the pebble basket filtration system at the top of the tank. This creates a very neat dual lighting effect, illuminating the entire Fluval Chi and the space around it.

It may not be the number one light for growing plants, but it certainly works to keep plants alive and fish happy. If you have any questions, you can visit the official page here.
