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.

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.

Really disappointed that I have to give this one star after all the research and reviews I followed before finally ordering. Set it up correctly however it just did not perform, very poor flow and vibration felt on the unit. Tried and tried again but still the same so it got packed up and sent back for a refund. I’ve just been unlucky to receive a bad unit I guess. Already have seven other canister filters of different manufacturers and sizes running on my aquariums so I was not expecting this when investing in what is supposed to be a very reliable unit.

Funciona perfectamente, gran potencia sin ruidos apreciables. Una buena compra …

Well this arrived I didn't think it would look like a certain kind of hoover lol ,I greased all the o,rings don't forget to do it and propeller , I changed some media I put in some bio plastic pond media in with the media it came with I have plants no fish , it is realy quiet but I thought it would be more powerful for its size with my 4ft aquarium, thou it's powerful enough it's doing it's job il not know fully till fish are in it after a month of cycling the aquarium , the purge pipe outlet seems very fragile it's not tough plastic and you kind of get scared of putting it all together in case it snapsand instructions are to small to read but it's not rocket science to figure it out just look at the picture , I'm happy with it overall and I am surprised it realy quiet I hear the water more than the pump I would recommend to anyone else make sure you put it in another plastic container just in case of leaks or when you want to clean it out and have enough room at the side ,underneath or back of your tank to put it, the purge tap is a great idea of fluvals but a fast water change of a few jugs you don't need itbut great when you will ,I am glad I own iti only wish the pipes where better quality and not cheap plastic thou the purge pipe is better quality than the other pipes, a size down from the fx6 would also be suitable for a tank my size of 4ft but I'd rather this size to be right depending on the choice of fish and what they eat if you have guppies or tetras this is fantastic or even African rock chiclids mubuna,s choose this your choosing right fluval do great products thanks fluval they have been going long enough to know there reliable well my opinion I've not had problems touch wood,has thus for a while now no problems all is good its keep my tank very clean 4ft tank water is clear may need clean it in a month or two the idea of keeping it clean don't over feed feed only twice a day and hzvd cory Dora cat fish yo help clean it and dori g onions with roots in the water gor removing ammonia from water and see how they grow.
