Features of Fluval FX6 Canister Filter

Works With Up To 400-Gallon Tanks

The powerful pump system of FX6 ensures filter circulation of 538 US gallons per hour as well pump output of 925 US gallons per hour. There is rule of thumb in the aquarium hobby that filtration should be 6x of the total water volume of the tank. But FX6 has an extremely efficient filtration system which gives it a competitive edge to server even larger tanks. If you have got a large aquarium or maybe even a medium-size one, FX6 will surely be sufficient. As the word goes – there is no such thing as over filtration!

Instant-Start Priming System

Most of the canister filters need priming before first use, and fortunately, FX6 has an instant-start priming system to get it working in just minutes. Though auto priming devices are standard in modern canister filters, they are of great value. You will only need to wait for 1 minute for the filter to pump water and another 2 minutes for it to drive out the air from the system!

Maintenance Reminders

With inbuilt monthly indicator signals, FX6 lets you remember the last time you performed maintenance. However, the high level of efficiency of this filter can allow you to not worry about often maintenance at all!

Multi-Directional Nozzles

Both input and output nozzles can be flexibly regulated to create directional water flow. This will be of great use if you, for example, want to reach the distant corners of the aquarium. Plus, you will have more control over the efficiency of FX6.

Capacious Media Baskets

Fluval FX6 comes with high-volume media baskets. Overall, FX6 can accommodate 5.7 liters of filter media, which should be quite enough for the whole range of supported aquariums. FX6 supports any type of filter media, be it mechanical, biological, or chemical. While this aquarium filter comes with filter media, they won’t last too long, so you should also think about getting spare media if you want to ensure constant water filtration in your aquarium.

Adjustable Water Flow

The AquaStop valves allow you to regulate the water flow of both the intake and the outflow tubes. In addition, you can do a 90-degree turn of the valves to stop the water flow, which in its turn will allow you to perform maintenance. But before, you definitely should purge all the water from the filter. Fortunately, FX6 has a purge valve to allow you to quickly remove the water from the canister with a simple turn.

Quiet Operation

With the precisely engineered bearing, FX6 features minimized vibration and thus operates quietly. If you keep your fish tank in the bedroom, FX6 may be the right aquarium filter for you.

Warranty

And lastly, Fluval FX6 comes backed up by a 3-year warranty.

Who Should Buy Fluval FX6?

Fluval FX6 aquarium canister filter is not cheap. Should you pay the high price for its features? If you absolutely need its functions, yes!

But if your fish tank is upto 240 Gallon you are good to go with FX6’s little brother Fluval FX4!

All in all, FX6 will be capable of dealing with any type of waste or debris, though be mindful that it will depend on the kind of media you use and also the number of pets in the water.

Quiet operation means that FX6 could be put in your bedroom aquarium. However, because noise tolerance of each of us is different, you should make sure that the noise produced by this model won’t disturb your sleep.

  1. I WOULDN’T recommend if you have sand substrate . The filter motor is at the bottom and can easily get damage by sand. My fx6 only lasted 2 yrs and sounded like and helicopter landed in my living rOom . You would think That a $300 filter cOulD handle sand.I also was not impress with the cleaning capabilities of the fx6 and I will stick with Eheim classics filters with the motor at the top of the canisters.
