If you are setting up a large fish tank, a good aquarium filter is one of the most important things you need. In addition, you need a mechanical, biological, and chemical filter to keep your fish healthy and the water clean and clear.
With that being said, finding a good filtration unit for your aquarium, especially one that performs as advertised, is easier said than done. However, this is what we have found for you – an excellent filtration unit that will keep your water clean.
Fluval FX4 High Performance Aquarium Filter
We will look at the Fluval FX4 High Performance Aquarium Filter, a very large and powerful external canister filter. It has an astounding flow rate, excellent filtration capabilities, and many convenience features. Based on the price, it has to be one of the best filtration systems for aquariums.
Who is This Product For?
The Fluval FX4 High Performance Aquarium Filter is for anyone who needs a large and powerful aquarium filter for a heavily stocked fish tank.
However, this unit is designed for freshwater use and should not be used for saltwater fish tanks.
This is a very large unit that can process up to 700 gallons of water per hour, and it comes with the three major types of filtration, making it ideal for the largest and the heaviest stocked tanks.
In the box, you’ll find a filter for a 250-gallon tank. It has the filtration media included, including mechanical, chemical, and biological. It also includes the metal clamps, flow clamps, an output nozzle, the intake, a small hose, and a large hose.
Overview of Features
The Fluval FX4 High Performance Aquarium Filter has many features worth talking about, so let’s do that now. First, this is an external filter, which does not take up any space inside the tank. With that being said, this is a large filter that will take up space outside of the aquarium, so you will need a fairly large cabinet to house it. It’s also a very heavy filter, especially when it has water in it.
This unit is ideal for fish tanks up to 250 gallons in size, which is massive. Moreover, this unit can pump up to 700 gallons of water per hour.
This means that it can process a 250-gallon tank nearly three times per hour, which should be more than enough to keep any fish tank clean and clear. It also features an adjustable flow rate, so you can turn it up or down as needed.
The Fluval FX4 High Performance Aquarium Filter is self-starting, making it very user-friendly in general. Simply add a bit of water and turn it on; the pump will take over and do the rest for you.
There are special valves that are designed with a leak-proof Click-Fit attachment system. Moreover, these valves are positioned at 45 degree angles, which makes for easy installation and rotation. You also get multi-directional output nozzles that you can adjust to create the type of water flow you need for your aquarium.
This filter features a stackable media basket system that eliminates the need for a water bypass. Moreover, these media baskets are pretty large. This filter performs all three significant types of aquarium water filtration – mechanical, chemical, and biological. Furthermore, this product comes with all of the filter media included.

Suppose the aquarium filter we reviewed today is too big and heavy for you. If this is the case, there are other good options. For instance, the Fluval 07 Series Performance Canister Filter for Aquariums is a slightly smaller and more affordable model from this same brand. It performs really well, it works for pretty large tanks, yet it is not as massive as the FX4.
Overall, we think the Fluval FX4 High Performance Aquarium Filter is an excellent option to consider. It’s big, it’s powerful, and it gets the job done.
