Alternate #2

With an attractive, modern design and incredible flow rate, this product provides you with performance that is comparable to the Fluval FX6 filter but with a much easier to handle exterior body.

Quick Summary of the Main Product

The Fluval FX6 filter is often known as a beast in the aquarium filter world due to its superior performance compared to most of its competitors. With its strengthened valves and supremely high flow rate, the Fluval FX6 is appropriately sized for aquariums all the way up to 400 gallons. It has a pump output of 925 gallons per hour and a filter circulation of 563 gallons per hour that both work to produce healthier results. 

Unlike most of its competitors which operate within the same flow rate range, the Fluval FX6 has a much smaller footprint. It has a height of only 21 inches that makes it relatively easy to hide inside your aquarium cabinet or whatever other setup you have for your aquarium. 

The interior of the filter is reinforced to ensure no leakage takes place and for a filter that handles 924 gallons of water every hour, it shows very little signs of clogging or debris getting stuck in it for extremely long periods of time. It’s often quite a while before you have to open it up to perform cleaning and maintenance. 

Features and Benefits

  • Reduced Noise Operation 

There are many aspects in the Fluval FX6’s design which help it operate very silently. 

Firstly, it has rubberized feet which assist in dampening the noise that occurs during filtration. It minimizes noise to the point where you might even start doubting that the filter is even on until you get right up close to it. 

Secondly, the internal motor is specifically designed to vibrate as little as possible during the process of filtration. The minimal level of vibrations occurring inside the Fluval FX6 plays a very significant role in it being much quieter than its competitors.

  • Multi-Directional Output 

The Fluval FX6’s design included twin output nozzles that you can direct in any way you desire. This comes in handy for a number of reasons. 

Firstly, you can adjust them to whatever direction you want in order to ensure that every inch of your aquarium is being provided with the filtered water. 

Secondly, these multiple output valves also play a major role in the flow rate of the filter since you can position them in a way so that your smaller fish are not disturbed or stressed from the currents that the filter is creating. 

The multiple nozzles can also have different modes of output running at the same time. This gives you an even more heightened amount of control over the flow of filtered water running into your aquarium. 

  • Auto-Adjustment Technology and System Monitoring

Fluval has installed an electronic circuit inside the FX6 filter whose job it is to ensure that the filter is operating at the optimal rate. It does this by monitoring the water levels inside the filter and then adjusting the performance and flow rate accordingly. The consistent monitoring not only helps the filter clean your water more effectively, but it also helps extend the filter’s life and longevity. 

  • Stop Valves

These valves are a welcome addition to the Fluval FX6 filter which many of its competitors have started copying ever since they came out with this innovative design. 

The aqua stop valves allow you to easily stop the flow of water to and from the filter any time you need to perform maintenance or cleaning. All you need to do is turn the valve lever and then you can perform all the cleaning you want without having to worry about water or air leaking from the filter or the damaging of filter components inside. 

Once maintenance is finished, you can turn the levers back again in order to let the filter resume operation.

  • Self-Primer System 

If you’ve worked with aquarium filters before, you may share the same annoyance that most fishkeepers have with the task of priming filtration systems. “Priming” essentially refers to the process of making the filter ready for operation before you turn it on. It’s a time-consuming task that is mandatory and can’t be skipped before you turn it on. Turning a filter on without priming it can lead to your filter’s motor burning out. Priming has to be done every time you turn the filter on, i.e., the first time you mount it onto your aquarium as well as every time after cleaning and maintenance. 

The Fluval FX6 filter makes this task non-existent for you through its self-priming mechanism. You don’t have to do any of the priming yourself. All you have to do is mount the filter onto your aquarium, fill it with water and turn it on. The filter itself does the rest. 

  • Clog-Proof Inlet 

You will notice that the intake tube of the Fluval FX6 filter has a telescopic strainer around it. This strainer is present there to catch a lot of the gunk and debris before it even enters the filter itself. 

This is a very handy feature since it allows the filter to run for a very long time before it needs any cleaning or maintenance. It reduces the workload of your mechanical filtration media and also reduces the chances of your filter’s tubing getting clogged. 

Not only this, but this strainer also prevents smaller fish from getting sucked into the filter. It catches them and keeps them there so they are not fatally harmed. If you notice any fish missing from your aquarium, we recommend you check the filter’s intake tube as you might find them stuck to the strainer.

  • Purge Valve 

The purge valve is a very unique feature of many filters that come from Fluval. It’s a valve that enables you to empty your aquarium without the hassle of having to use buckets to chug water out of them repeatedly. All you have to do is attach a hose to the purge valve and open it. The water will drain out to wherever you want. This is very convenient for whenever you want to do water changes or when you want to empty your aquarium entirely. 

Pros and Cons

  • The Fluval FX6 filter features an unmatched level of build quality. The body has a premium feel to it and apparent durability which ensures that the filter will be able to withstand the test of time and will last you a very long time. 
  • Despite the number of features it’s packed with, the Fluval FX6 is extremely easy to use. Fluval strives to make this filter as user-friendly as possible. Features such as the self-primer aim to reduce the workload for the user as much as possible. 
  • With its incredibly high output and filtration rate, the Fluval FX6 filter is able to handle extremely large aquariums and is appropriate for both saltwater as well as freshwater aquariums. 
  • It features excellent water management and a smart design which ensures that the minimum amount of water is wasted. 
  • Due to the number of diverse features packed into this filter and the electronic smart circuitry it boasts, it comes with a steep price tag. While there’s no doubt you definitely get what you pay for with this filter, there’s definitely a chance that many fishkeepers won’t be able to afford it. 
  • Considering its durable exterior, the body of the Fluval FX6 filter itself is quite heavy. You may have trouble handling or relocating it if the need ever arises. 

Social Proof

We’ve had a wonderful experience with the Fluval FX6 filter but we also wanted to know what other people’s experiences have been like so, we delved into the online reviews to find out. Most customers we encountered were highly satisfied with it with only about 15% of reviews being critical of the product. 

We even found customers who gave yearly updates to their reviews in regards to the performance of the filter. There were reviews that confirmed that the filter was running like it was brand new even after years of use. 

Users also appreciated all the extra features that the filter has such as the purge valve. The self-priming feature was something that seemed to be a big selling point as almost every review mentioned how the filter is able to start running instantly which they found very convenient.

Guide to Buy

  • Durability – Fluval Fx6 Review

A lot of companies have started to cash in on the ever-increasing popularity of fishkeeping as a hobby. This means that a lot of companies have started manufacturing aquarium filters with subpar materials that break down after some weeks of use. 

When you go out to buy a filter, make sure it’s well-built and consists of materials that will enable the filter to operate effectively for a long time. 

  • Power Efficiency 

Getting a cheap aquarium filter is not often the best way to save money. Sometimes the most effective way to save money is to get a filter that’s smartly designed so that it utilizes power efficiently. This will be much more cost-efficient and will save you a lot of cash in the long-run.

  • Operating Capacity

You have to figure out how much flow rate you want your filter to operate at and to figure that out, you have to look at how big your aquarium is. This is important to think about because you have to balance adequate cleaning with the peace of your fish. Having too strong a filter can disturb or even kill your fish so this is very important to think about before you go out and buy a filter. 

  • Cost

When it comes to cost, you have to strike a balance between getting a filter that can be as good as it can within whatever price you’re allowed by your budget. Although we encourage saving money, we definitely don’t recommend that you get a generic filter from an unknown brand to do it as that could have unforeseen, undesirable consequences such as the filter breaking down, the filter not filtering the aquarium effectively or even worse, polluting the environment of your aquarium
