Fluval FX6 High Performance Aquarium Filter, Canister Filter for Aquariums up to 400 Gal.

The Fluval FX line of filters is a real work horse which rarely goes wrong if you do the upkeep on it. I use one on the tank I have my turtle in, and it keeps the water crystal clear, even though the old boy digs a lot an tries everything he can to cloud up the water. If I take it off line for cleaning (which is a breeze) or maintenance, it will get the water clear again within an hour if the turtle has been very active while it was off, and much sooner if he wasn't moving around too much. He's a very active turtle, and a very messy eater, but he's neither active enough nor messy enough to overwhelm the FX-6. I also use an FX-6 on my hillstream tank which requires a lot of flow. It pushes the water through at a very good clip so that the stream has a pretty good current for my hillstream loaches and for my rainbow shiners to run in when they're getting ready to spawn. I have the FX-4 on a 20 gallon tank which is probably just a bit overpopulated, But again, it is a good enough filter that it keeps the water quite clean. With surface skimmers on my tanks, even the water's surface is clear. To clean the filter media, all you need to do is lift the media baskets out, the use the filter's bucket to clean the sponges and reusable media, replace the media which has broken down too much to be reused, or which uses chemical treating, then either empty the old water out and replace it with fresh clean, or keep the old water if it's not too bad (it is almost always too bad). The reason you clean the media in the water the filter bucket has in it is so that you don't loose any of the beneficial bacteria which is growing in it. The FX series of filters have variable flow valves, which is a nice feature, though many filters have that. If you close the valves before opening the lid of the filter, you don't have to worry about draining the hoses, and they will be good to go when you turn the filter back on and open the valves. No priming needed. Everything in this filter is easily repairable if something goes wrong. If something happens which wears out the impeller, it's very easy to take the old impeller out, and drop a new one in. It's also easy to replace all the O-rings when they get old and start to loose their ability to seal the unit. If you're unlucky, you might need to do that once a year, but it's more likely that you'll just need put new lubricant on them. I am mechanically challenged, so if I find it easy to take care of, I'm sure just about anyone will be able to do it. I have had problems with several of the other big brands of filter makers, but I have never had a Fluval FX series filter go south on me. I recommend them to anyone who wants to keep their fish's environment clean and healthy. If I ever start another tank, I'll definitely be buying another Fluval FX.

Ive been running the Fluval for about 3 months now, and I am absolutely OBSESSED with its quality. I have a 75 gallon tank with a turtle and pleco (both produce A LOT of waste). Previously I was a die hard Penn Plax Cascade fan for the last 5 years, but my last two had motor failures and they changed their warranty terms finally, so I decided to switch it up. Long ago I wanted a Fluval, but but the price was steep so I settled for less and let me just say it’s the best investment you can make. It’s quiet (don’t know why other reviews say it’s not unless they are keeping their water levels really low), my tank remains crystal clear with my normal monthly maintenance routine, and it is easy to clean and change out my media. The fasteners are really not that complicated and don’t take that long to unlock like other reviews say. The canister itself is designed so that it is air tight and I’ve had no signs of leaking. The outtake is made so you have two options to direct the flow of your water which is helpful if you have a basking platform above half of your tank. Highly recommend.

In my opinion, Fluval makes the best filters, absolutely silent when properly maintained. I bought the FX6 to take the place of two 406s I have been running on my 90 gallon aquarium. It took me a while to figure out the filtration flow path but it became obvious after understanding the internal tubes. Still, it would be nice to have a flow diagram included in the owner's manual. The only issue I experienced was more related to the placement in my stand/cabinet but I must assume that most people would run into the same issue if they have a similar cabinet. I wish Fluval would consider using better rubber feet on the legs to prevent vibration but I used rubber/cork pads to isolate my Fluval FX6 from the cabinet floor. The tiny rubber pads that came with the filter were not enough to prevent the filter from developing a low-frequency vibration that resulted in the whole cabinet emitting a very annoying hum. The filter itself is very quiet but sitting in the hollow cabinet allowed the conditions to arise. The filter does not touch the sides of the cabinet nor do the hoses so I knew the filter feet (3) were the only contact point. As soon as I placed these under the feet the vibration ceased and no more humming noise in the living room! Worked like a charm and for less than $8, a very cheap fix! (Bought on Amazon). As I imagined, the FX6 is keeping my water crystal clear with the filtration setup I am using internally that includes Purigen and 2 polishing pads in the last stage. I trust I will get 3 month between cleanouts that I was getting with the 406s with bi-weekly 25% water changes. Been up and running for over a week now and water parameters are perfect. Very happy with this filter. If you have a vibration issue, this should help you eliminate it as well.

Très bon filtre, utilisé pour 2 tortues d'eau, le bruit est résonnable, l'eau reste clair et très propre, le débit est correcte. Le montage est vraiment facile, tout est expliquer en français et detailler avec des illustrations. Pour le nettoyage, rien de plus simple, on peut brancher un tuyau sur la sortie vidange pour vider le contenu et il peut se remplir avec l'eau de l'aquarium, franchement c'est super pratique. La pompe, toute les 12h chasse l'air contenu dans la pompe, tout est automatique, même l'amorçage ! On le branche et ça démarre. Pour l'instant aucune fuite, tout fonctionne très bien , livrer avec des joints en supplément. C'est peut être un peut cher mais côté pratique et gain de temps et performance, je ne regrette rien.

Fluval FX6 ha risolto i mimei problemi di poca dimensione del filtro nell'acquario. Acqua pulita, cristallina e niente più alghe. Le vecchie stanno sparendo e il fondo non ha più residui. Potente e silenzioso. Comodamente riposto nei vani di un Juwel Rio 450 (o Vision 450). Comodo da pulire. Qualche adattamento da fare nella parte superiore dell'acquario (lo ho preferito a fare fori nel vetro). I tubi possono (devono) essere migliorati come estetica e qualità del tubo da parte del produttore, sono grandi, ma gli attacchi rapidi sono ottimi e dotati dei rubinetti di chiusura e apertura. Nulla che dire ottimo investimento. La pulizia del filtro è facile, finalmente niente bagnato o stracci ovunque. Speriamo duri nel tempo.

Great filters. I have 3 FX6s and 1 FX4. They run great and do not need much maintenance at all ADVISE: These are expensive so make the most of them! - Get a prefilter (this will make you only having to clean the filter every 6 months. or even more = Less openings and longer life of filter) - Get Food Grade lubricants for the O-Rings. Apply every time you open the filter! Important to avoid leaks! - Clean the impellor once a year. The output gets a lot better and extends filter life - Do not change the sponges. Only clean the sponges. Changing the sponges and media is only good for Fluval profits but contra productive for the biological filter. (Sorry fluval but the truth) Sponges last for years. Seriously. Also load the filter up with only sponges or pot scrubbies. Ceramical rings are sub optimal.

الفلتر رائع ويعتبر من افضل الفلاتر للاحواض الكبيرة , لكن المفاجاءة التي لم اتنبه لها هي كهربة الجهاز صار منه موديلين موديل يجي 110 مع 60 هرتز تردد والموديل الثاني 220 مع 50 هرتز . علما ان الكهرباء في السعودية 220 هرتز مع 60 هرتز , واضطررت اني اخذ محول للكهرباء . والموديل الموجود من امزون امريكا هو 110 هرتز.

These units are made sturdy very thick plastic buckets with a powerful motor to filter large amounts of water!. I am currently using this on a saltwater tank and it is holding up against the salt after two solid years of running. Also there are complete seal kits that you can buy for maintaining the filters life it even comes with a new impeller and ceramic drive rod assembly and all seals needed. All parts are available and change out easily if broken Fluval though of everything with this filter.
