From its ease of use to its extreme efficiency, it’s a great choice for any larger household aquarium. This is a durable product, and the brand Fluval is known for good customer support, so you won’t have any problem with after-sales service.

It is highly recommended for anyone that are keeping overstocked aquariums such as African cichlid tanks or any other fish in your tank that causes chaos and lots of debris.

What’s Included

Out of the box, you will get the filter, obviously. The unit comes with three huge media trays that are very durable. You will also get the intake and outtake pipe, which are somewhat short, but you can buy longer ones.

In addition, you will find the power cord and pump unit in a separate box that also includes rubber feet, suction cups, two bio-foam inserts, two media packs, three media baskets, a carbon filter pad, one drain cap and utility valve, and a purge valve hosing.

Overview of the Features

Let’s have a look at what features this canister filter has to offer.

Smart Pump Technology

First of all, let’s talk about its built-in electronic controller, aka the smart pump technology. This controller continuously monitors the pump, its output force, and the impeller speed.

To keep the filtration system at its maximum efficiency at all times, this system automatically pauses the machine when air builds up inside the system. It will release the trapped air once every 12 hours.

400-Gallon Capacity

This filter has a high capacity that makes it stand out among all the other aquarium filtration system. That doesn’t mean that it can handle tanks with a capacity of 400 gallons.

While it does lack circulation rate and the fact that it takes about 45 minutes to circulate a tank of 400 gallons capacity thoroughly, it makes up for that lack of circulation rate with a powerful, high-performance pump.

Size

The canister itself is surprisingly small despite having a high-capacity filtration system. The whole unit will fit neatly under most aquarium cabinets as it is only 21-inches tall.

Connectors and Valves

For ease of use and easy maintenance, this filter comes with a pair of AquaStop valves and click-fit connectors that you can use to fit all the components of the FX6’s together. 

This is a highly appreciated design of the system as the connectors simplify the whole process of joining the valves by simply pushing them down onto the filter housing. You will hear a clicking sound that will let you know that the seals are water and airtight.

You can turn AquaStop valves 90-degrees to stop the water flow through the outflow and intake tubing. This allows you to purge the filter easily.

This will also save a lot of maintenance time because you can easily disconnect the tubing and won’t have to worry about water leaking out.

Purge Valve

The valve is located at the base of the canister. When the intake and output lines are closed, you can open this valve to remove any water that is left in the filtration system.

Media Baskets

The most important component of the Fluval FX6 is its media baskets. It has three of them, which can be quickly removed via the simple T-handle release. You can access the filter media on each of them as they are separated.

They are stacked on top of one another, and the whole system is designed in a way that makes it very easy and fast to change media and maintain them. You can also customize the filter media to your liking.

The stock media is good for most aquariums, but if you want more, try some other filter media or ask the pros and see what they are using to make their tanks clear.

Instant Priming System

This machine will start on its own once you set this one up. It will first fill the canister with water, and then it will start pumping. To evacuate air from the system; the machine will pause the pump for 2 minutes.

After that, the pump will start filtering your tank. Long gone are the days where you had to figure out manual siphoning. This is a plug-n-play filter, and honestly, this should be a standard feature among all other canister filters out there.

How to Install

The setup is very simple and easy to install. You won’t have any problems or frustrations when putting it together. As soon as you open the package, it comes with a very clear instruction manual. So, I don’t think I’ve to point out the steps here.

Alternatives

There are two similar models;the FX5 and the FX6. If the prices are close, just go with the FX6. For the money, there isn’t really any alternative.

Conclusion

You will see the results of this filter after running it only for a few days. The water clarity will improve drastically with a steady water flow as well, and you will really feel like you have made a good investment. You will see a noticeable improvement from your previous setup.

I hope you enjoyed this review on the Fluval FX6. For household aquariums that are up to 400 gallons, this one is a beast of a filter.
