Product Description

canister
The Fluval FX5 Canister Filter offers unparallel filtration power, maximum versatility and incredible control in fine-tuning water characteristics. The multi-stage system allows you to stack filtration media in the precise combination of layers that will work best for your aquarium. In the end you are provided with infinite flexibility in creating and maintaining the ideal environment for your fish.

It’s massive capacity and powerful integrated motor processes and re-circulates 563 gallons of water every hour enabling you to precisely manage water conditions for aquariums as large 400 gallons. It will hold up to 1.5 gallons of media, yet it is compact enough to fit under almost any aquarium cabinet.

With Fluval’s unique Smart Pump technology, this self-priming system offers plug-in-and-start convenience. Upon start-up the canister fills with water, pauses to evacuate air, immediately begins the filtering process and continues filtering until it is unplugged. Once every 24 hours, the filter will pause again to evacuate any air that has become trapped in the system to maintain the total vacuum necessary for maximum efficiency.

Fluval FX5 Details

• High performance, canister filter for aquariums up to 400 gallons.
Multi-directional Output Nozzle – Twin-output nozzle can be adjusted to create specific water flow to reach all corners of the aquarium.
Self-Priming Instant Start System - Just add water and plug in. The FX5 has a “Smart-chip” in the motor, allowing it to be self-priming.
Smart Pump Technology – Allows system to shut-down and purge any trapped air, every 24 hours. This procedure eliminates any accumulated air-pockets, within the canister, providing you with maximum performance.
Aqua-Stop Valves – Unique “Click-fit” technology allows for fast set-up and leak-proof maintenance. The valves rotate 360 deg and are directed at 55 degree angles for easy positioning. The flow control allows you to regulate water flow, with no harm to the motor.
Purge Valve – Allows for partial discharge of debris, without disconnecting or opening filter. It can also be used to drain the aquarium utilizing the filter pump. This is beneficial on large aquariums.
Multi-Functional Rim Adapter – Innovative rim adapter easily secures hosing and fits most standard trims.
Clog-free Strainer – Heavy-duty anti-clogging strainer prevents blockage, even in a planted aquarium. Maintains constant water flow, even when covered with solid waste.
Electronic Circuit Board – Continuous monitoring of impellor speed and pump power ensures optimum output and efficient energy usage. Motor will turn itself off if impellor is impeded.

Product Features

AquaStop Valves
aquastop
The AquaStop valves make maintenance easy by allowing you to stop the water flow with an easy 90-degree turn of the valve lever. This means you can separate the hosing from the filter in one step. The valve lever can also be used to regulate water flow with no harm to the motor or its components. Three valves are provided: one for the intake, one for the output and one to be used to drain the filter under certain circumstances during the maintenance process.

Click-fit Connectors
clickfitconnectors
Click-fit connectors are designed for quick set-up and leak-proof maintenance. You just push the intake and output assemblies (Aquastop valves and attached hosing) down. Once you hear the “click,” you know the connection is secure and watertight.

Lift-Out Stack of Media Baskets
media baskets
The lift-out stack of media baskets is at the heart of Fluval multistage filtration. These large capacity baskets enable you to stack filtration media in the precise combination of layers that will work best for your aquarium. Use one type of media in each basket, or layer two or three types to suit your aquariums needs. Each basket is lined with a foam insert for effective mechanical pre-filtering. The instant-release T-handles let you lift, then separate the basket stack quickly and easily, making routine maintenance simple.

High Capacity Canister
The FX5’s compact, super capacity tank processes and re-circulates 563 gallons of water every hour and accommodates the stack of media baskets with their capacity of up to 1.5 gallons of media. Yet this enormous-capacity tank is short enough (21 inches) to fit under most large aquariums.

Key Features

Multi-Directional Output Nozzle
outputnozzle
The flared spout of the adjustable twin output nozzles sends multiple streams of purified water toward all corners of the aquarium, creating currents that agitate the water to break down wastes and help hold them in suspension until they can be drawn into the filter by the intake strainer. With more waste solids kept afloat, fewer settle, which means that bottom surfaces, and in fact the entire aquarium, is kept cleaner.


Clog-Proof Intake Strainer
intakestrainer
The wide, rounded mouth of the FX5 intake strainer is shaped to siphon water quickly. Covered by a fine screen that’s beveled to repel debris, it is virtually clog-proof, so there is never a build-up of solids that could impede water flow.


SMART PUMP™ Technology
Designed and engineered for reliable filtration of delicately balanced aquarium environments, Fluval’s FX5 Smart Pump technology employs an electronic circuit board to continually monitor the pump. Impeller speed and force are constantly measured to ensure powerful output and energy efficiency. Smart Pump technology is also critical in evacuating any air that may build up in the system. Once every 24 hours, the filter will pause and allow any trapped air to escape, thus maintaining maximum filtration efficiency.

Self-Priming Instant-Start System
With the FX5, there’s never any need for manual siphoning. Simply fill the canister with 2 gallons of water, plug the filter in, then the filter will complete the filling process from your aquarium. It pumps for 2 minutes, pauses for 2 minutes to evacuate air then restarts immediately.

Purge Valve
The FX5 canister features a purge valve drain at its base. This makes it possible for you to empty the canister for maintenance before moving it.

The Fluval FX5’s superior performance and capability are backed by Fluval’s well-earned reputation for the best fish and aquarium care. Hagen Aquatic Research Station certification is your assurance of the most up-to-date and reliable research in aqua-care science. The use of the Fluval FX5 will help provide your fish with the aquatic home they deserve. *The FX5 helps meet the desired objectives of any aquarium. For the best performance, the Fluval FX5 Filter should be placed completely beneath the aquarium.

I've had my Fluval FX5 since summer of 2008 and have been running it non-stop since then on a 125 gallon freshwater aquarium. In 2009 I added a Coralife Turbo-Twist UV Sterilizer (36 W) and my water has been absolutely crystal clear for months at a time (I highly recommend this addition). The few times I've noticed it get a little murky (when the curtain was open and sunlight enhanced algae growth) it was totally clear within 12 hours.

The Fluval FX5 is a great filter but requires regular cleaning (every 1-3 months full filter clean). However, you don't need to replace all of the media each time you clean the filter (which can get really expensive). Instead, you can use a garden hose or similar very strong spray to clean the main filter sponges (around the edges of the filter) and the blue filter pads. The white polishing pad should be replaced regularly. I rinse the bio media in tank water and dechlorinated fresh water to get rid of any chunks of things.

As others have said, expect a tiny bit of water when you close the valves and remove the hoses to move the filter, which makes sense since there's about 2" between the valve shut off and the filter. I keep a towel wrapped around when I remove the hose and have never had an issue with getting my hardwood floors wet.

The filter, when full of media and water is heavy but not too bad. It weighs around 40-50 lbs like that (depending on your media).

I suggest having tube cleaning brushes on hand to clean out the intake and output tubes (the ones in the filter - no need to remove the filter tubes from the filter to the aquarium). Otherwise a sponge will clean the inside of the filter perfectly and a strong spray will clean everything else.

When it's running it is incredibly quiet.

I've been running the FX5 on a 125 gallon turtle setup for about two months now. Setup is very easy, especially if you have previous experience with canister filters. I saw another review that stated that the filter was noisy, but mine is pretty quiet even when the tank stand's door is open and the filter is exposed to the room. My flowrate has been relatively high, especially considering that it is packed with biomax and polishing pads. It is important to note that unlike other Fluval canisters, this beast actually filters water from top down, so you'll want your finer media like polishing pads in the bottom basket.

I docked a star because I am not a big fan of the design of the internal media baskets, nor do I like the cheap plastic 'T' rods that are used to pull them out. Also, despite the stop valves on the intake and outtake hoses, be ready to clean-up water when detaching for routine cleaning.

Although the Eheim Professional Canister Filters are arguably better for certain purposes, you aren't going to beat the value of the Fluval FX5. The features and specs you get are equivalent to several much more expensive filter options.

I'll keep it short and to the facts.

The FX5 does everything it is advertised to and is very quiet. I am using it on an 85 gallon freshwater tank stocked with 7 3-4 inch African Cichlids, 10 2 inch clown loaches, 10 tiny convicts, one 6 inch plecostomus, and 2 one inch rays. I only add aquarium salt to the tank and treat the tap water with Aquasafe during 25% water changes once a week; no other chemicals. After running the FX5 for 3 days I tested the water for ammonia (0 ppm), ph (7.5), nitrite (.5 ppm), and nitrate (40 ppm); all within tolerances for an established community tank, albeit a little low for the cichlids.

My conclusion? The FX5 rocks and is well worth the money.

My long journey to this conclusion (in short form)-

I read all of the reviews and ordered an Eheim Pro 3 2180 a couple of months ago. Sent it back immediately because I use salt in the water and that would destroy the internal water heater and subsequently the pump (according to the Eheim technician).

I then ordered an Eheim Pro 3e 2076; it came, it leaked profusely at the pump-to-canister seal (made an incredible mess), tried all of the solutions mentioned in the troubleshooting section of the documentation, called the tech line to no avail, returned the pump for full refund.

I then ordered an Eheim Pro 3e 2078; it came, it leaked profusely at the pump-to-canister seal also, became disgusted at the product quality, returned the unit for a full refund.

I then ordered the Fluval FX5; it came, it worked as stated, I'm very happy!

Hope this helps.

I got one of these from my local F/S, and it works great. It is very large though, which to me is a good thing. More Water volume which is always a plus with saltwater aquariums. It comes with a DVD that tells you how to set it up. You don't really need the DVD, because it is quite simple to set up and get started. It comes with more than enough hose to do the job. I have the hose coiled around in the bottom of my stand it is so long. Every night it shuts off to let the air bubbles escape and then turn back on. You don't have to do anything to start it. So far their have been no leaks or mechanical failures.
