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

Absolutely! Hands down the best canister filter out there. If you don't have one and you're waiting, stop, go get it now, you won't regret it. There is no noise. It's easy to install. The flow rate is superb. Water clarity is spectacular. You couldn't ask for anything better. Go get you one! What are you waiting for?

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.

So, it's only day one of having my tank filled and filter running, but that's all I needed to have enough information to write an initial review. Why? Three reasons. I'll start with the easiest...as with my experience with the Fluval 306 in the past, the FX4 is extremely quiet, which is an absolute must!!! Second, the filter is extremely easy to set up. Finally, because I don't have any standard faucets where I can use a hose adapter, I tried a couple other ways to fill my tank...both of which failed. I finally decided I would just carry buckets of water over to the filter and try out the pump function of the FX4 and HOLY MOLY, what a life saver!!! Yes, with a 120 gallon tank, it took 20+ trips from my kitchen sink to the aquarium (I'm going to figure out a simpler plan for water changes that's for sure :) ), but the pump function work flawlessly and vwalla, tank filled! Fluval has never let me down. This is the third filter of theirs that I have used... I definitely recommend them to anyone trying to decide which one to use.

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.

Great size and functionality, using it for a 600 liter aquarium, doing g a great job.
