Gute Ware, schnelle und unkomplizierte Lieferung, gerne wieder.

In meinen Aquarien, Gesamtinhalt ca. 1500 Liter, laufen seit 2021 inzwischen drei von den Filtern. 2x U4 und 1x U2. Sie fungieren als zusätzliche Partikelfilter. Die Filterschwämme werden dabei wöchentlich gereinigt. Für die biologische Filterung befinden sich andere Filter in den Aquarien. Bei der Fütterung der Fische (Erdfresser) kann ich die Filter für ca. 30 Minuten abschalten. Dann schalten sie sich selbsttätig wieder ein. Das funktionierte am Anfang auch recht gut. Seit einiger Zeit bin ich aber mit dem Anlaufverhalten nicht mehr zufrieden. Wenn ich den Stecker ziehe stellt das kein Problem dar. Ich entnehme den Filter, zerlege ihn (komplett) reinige ihne und baue ihn wieder ein. Es ist bei allen drei Filtern so. Nach einem Stromausfall stehen aber alle drei Filter und laufen nur nach der o.g. Prozedur wieder an. Leider kann ich die automatische Abschaltung auch nicht mehr nutzen. Sonst bin ich mit Leistung, Bedienung und Wartung (ich tausche wöchentlich die Schwämme) sehr zufrieden.

Einwandfreier Filter . 60 l Becken wird super gefiltert . Das beste sind die einzelnen Filterpatronen . Super zu reinigen . Ich bin total begeistert! Das beste ist : er ist so leise man muss schon genau hin sehen das er läuft . Wirklich 1a

Ho appena acquistato un nuovo filtro per il mio acquario e devo dire che sono davvero soddisfatto dei risultati ottenuti. Questo filtro funziona in modo eccellente, garantendo una pulizia costante dell'acqua senza alcuno sforzo.La cosa che più mi ha colpito è la sua silenziosità. Rispetto al mio vecchio filtro, questo è praticamente inudibile. Non solo è piacevole per me non sentire costantemente il rumore del filtraggio, ma anche la mia tartaruga sembra apprezzare la tranquillità. Posso dire con certezza che il mio animale si sente più a suo agio senza interferenze sonore fastidiose.Inoltre, la facilità di pulizia di questo filtro è davvero un punto a suo favore. Basta rimuovere il meccanismo di filtraggio e sciacquarlo con acqua corrente per eliminare i residui accumulati. Non è necessaria alcuna procedura complicata o l'uso di prodotti chimici. È un'operazione rapida e indolore che mi permette di risparmiare tempo e fatica.Ma la cosa migliore di tutte è che grazie a questo filtro, posso cambiare l'acqua del mio acquario con meno frequenza rispetto al filtro precedente. La qualità dell'acqua rimane costantemente alta e pulita, senza dover fare interventi continui.La mia tartaruga sembra molto più felice e il suo ambiente è molto più salubre. Sono davvero contento di aver acquistato questo filtro per il mio acquario. Lo consiglio a tutti coloro che cercano un prodotto efficiente, silenzioso e facile da pulire. Non ne rimarrete delusi!

Ich habe den Filter jetzt 4 Wochen in Betrieb. Aquarium mit 180 Liter und geschätzt 150 Liter Wasserinhalt netto. Mittlerer Fischbesatz (Viele Sammler, Panzer-Welse...). Der Filter macht einen sehr guten Eindruck (Verarbeitung, Strömung...). Die Pumpe ist zumindest für Wohnzimmer/Flur leise genug. Hervorragend ist die Reinigungsmöglichkeit durch die 3 leicht herausnehmbaren Filterpatronen. Das geht in wenigen Minuten. Inzwischen habe die Aktivkohle"Pads" entfernt und in einer Patrone feine Filterwatte eingesetzt (selber zugeschnitten). Wasser klar. Wasserwerte in Ordnung (Nitrat/Phosphat). Meinerseits eine Kaufempfehlung ......

Positiv: der Filter ist einfach zu installieren, Filtermaterial ist okay, Kabel ist lang genug, minimale Laufgeräusche.NEGATIV: nach 5 Tagen löst sich die Saugnapfhalterung von der Scheibe! Nach Reinigung und erneutem Ansetzen: Saugnäpfe lösen sich nach 5 Minuten. Ich habe neue Saugnäpfe gekauft von Fluval und: der gleiche Erfolg.Fazit: die Saugnäpfe sind zu klein für den Filter > Filter okay, Halterung unterirdisch schlecht.Nachtrag: nachdem der Filter 3 Monate in Betrieb war, noch 1 Stern Abzug!! Das Filtergehäuse lässt sich nicht mehr zerlegen für die Reinigung, das Gehäuse ist verkantet und nichts geht mehr. Resultat: keine Kaufempfehlung!!!

Manque les filtres. A acheter séparément mais ce n'est pas indiqué ici. Dommage. Retour et remboursement.

I really like it. It works well for my 30l aquarium and I prefer this one rather than Stingray, that I had before. It is easier to clean, less chances for fish to be trapped and there is a space for bacterial substrate. And it is silent. The only downside is that you cannot change sponge without detouching the filter from the wall. I hoped it will be as easy as with Fluval U2. But it's very minor problem.

This is a long term review as this exact filter was bought April 2018 and used yearly/monthly/weekly/daily/hourly/minute by minute ever since !I've been a Fluval customer for decades, I've had a number of their filters with dozens upon dozens of tanks over the years and what keeps on me being loyal?1. Quality2. Dependable3. Does it's job day in day outI've been in the hobby for decades and have kept salt/fresh bare bottom/planted and everything in between. I've given speeches, helped 100's of people in this hobby and in all that time and experience you can easily weed out poor manufacturers and you quickly gravitate to manufacturers who provide that dependability that is DEMANDED with the aquarium hobby.In all my years I've never had any Fluval filter quit working for me. Personally I'm in the underwater/submerged phase of tank keeping I guess you can say. I've converted all my main tanks with the Fluval U series and three tanks have this same Fluval U3 for a few different reasons, most importantly is for it's silent operation. I have a couple tanks in bedrooms and the old HOB Hang On Back type filters tend to let the water drop too far as to create that waterfall noise. Some may like that noise but I call it noise for a reason. With the underwater series such as this U3 there is zero and I mean ZERO noise from the filter.No fish stories here so I included the three U3 series filters as proof.For the filter itself, you can adjust the outflow in various regards, the filter unit itself clips into a holder which is suction cupped to the aquarium glass wall and opening the top door to change filter material is quick and painless. If the filter does not sit well in the filter cage something is just blocking it a tad, most likely it is the power cord so just rerun the cord past the clips on the back of the filter and your good to go again.TIP ► When doing any tank filter maintenance I strongly suggest to turn it off first. When I do filter maintenance I completely remove the entire filter into a bucket and then open it to change out filter pads. I do this because if you change filter pads in the tank and plug the filter back in, debris will shoot out of the filter like a hurricane. Change out filter pads in a bucket, rinse the filter itself in some water and you've minimized the debris hurricane.TIP ► There are 5 basic areas within the filter.1. The ceramic media. Never clean this part...leave it nice and dirty. Caked in debris isn't needed but if there is just remove that debris, don't try to 'wash' the ceramic rings. They also don't need to be replaced. If they are turning into powder, sure but in all my years I've never had to replace ANY ceramic media !2. On either side of the filter there is a course then fine area. The course is the sponge and material is first trapped into this. When you do your REGULAR maintenance squeeze this out in water only. You don't need to replace this as the sponge will last for many, many, many years.3. The final stage is a bad that 'polishes' the water and this includes activated carbon within that filter pad. In my tanks I don't run activated carbon and I caution against using that in most cases actually, so when my filter pad gets dirty I only squeeze this filter pad out in water and I don't replace it. The filter material's integrity against the plastic filter pad cage will last for years and years. People replace their filter material much too frequently.Sorry aquarium filter manufacturers... But they all tend to advocate replacing the filter material wayyyyy to frequently. Replacing filter materials is a huge profit maker for manufacturers.TIP ► In doing filter maintenance when a filter sponge or pad needs to be rinsed some people state to not use tap water as it contains chlorine and possible chloramine so those people say you should only rinse out filter material in cycled tank water. For my own practice I use tap water and I'm never concerned with the tap water chlorine or chloramine.TIP ► In doing filter maintenance only do ONE SIDE at a time. Since the beneficial nitrifying bacteria is held in the filter material if someone were to 'clean' the entire filter - all filter material, the tank can be put into a mini-cycle. Not really a good thing. Only clean 50% of the filter per time, doing this will give a more chemically stable aquarium.TIP ► A dirty filter is a wonderful filter. While you don't need to live with 50% water flow rate from the original brand new condition, people hurt their tanks by cleaning filters too frequently. The nitrifying bacteria is held in the filter material so cleaning the filter too often will easily cause a mini-cycle which will always put stress on livestock. Crystal clear water = dirty filter. Clean filter = zero cycle. Might sound strange but it's the truth.TIP ► If you hear the word ' cycle ' with this hobby that is in reference to a naturally and beneficial occurring chemical process where ammonia is converted to nitrite and then over to nitrate. A brand new tank will take aprox 30 days naturally for this to happen. At that rough 30 day mark PPM readings will be 0 ammonia, 0 nitrite and a reading of nitrate. In terms of fish you need really nothing for nitrate so your reading can be low however if you have live aquarium plants a reading of nitrate is mandatory.TIP ► In all my impeller filters, right out of the box I use a small dab of 100% pure petroleum jelly and rub it all around the magnetic part of the impeller. This will help with lubrication and a small tweak we can do to even further make the tank more quiet. Not gobs are used just a thin coat. I've done this for a very long time and there have been ZERO negative effects in any of my tanks. If this is not done, that beautiful slime coating found in mature aquariums will form within a couple weeks and naturally coat the impeller. I still just use the petroleum jelly anyways.TIP ► Please be very careful about filter placement especially if someone has fine substrate material especially such as sand. This can easily get sucked into the filter and once it hits the impeller it could easily give a louder grinding sound. When people come to me about grinding filter noise this is the first thing I ask them to check. Make sure the impeller cage is 100% clean of any debris. I typically say no closer than 4" so the substrate bottom when people have those fine grain substrates. Standard type gravel size which I only use, I can let the filter stand right on the substrate itself.TIP ► If by chance you have any sort of filter that the impeller appears to be caked with material and cannot be washed off just use a fine piece of sandpaper. Something like a 200 grit is what I have used in the past to make sure there is nothing 'stuck' on the magnet that can cause unwanted noise. This goes to any brand of magnetic impeller filter. You don't need to grind the magnet away just make the surface clean once again.TIP ► My first tip above talked about a dirty filter being wonderful and people clean it too frequently. This is 100% the case...however if your filter requires cleaning more than every 2-3 weeks then it is not the filter but the tank itself has a maintenance issue. If could very well be a buildup of mulm/detritus from lack of regular tank maintenance. Your filter will collect floating debris however if there is too much floating debris then any filter no matter brand or size will clog. That is our issue not a filters issue of not functioning properly. An aquarium filter's purpose is to COLLECT floating material not to magically make floating material 100% disappear. It is OUR regular maintenance job to remove that collected material.TIP ► A simple way to see if a filter is working properly, HOB, underwater or whatever is if water is being moved by the output. If water is being moved, the filter itself works. If the water is only moving 50% from original flow rates that means it is a very dirty filter that needs our cleaning maintenance...the filter did it's job just fine as it collected the floating material....the 50% flow rate is our issue with tank maintenance.There is much more I can write but I'll cut it off there. Good luck with the hobby, keeping aquariums is a wonderful thing.This brand is legend...please don't let someone else tell you otherwise.=====================Overall: 10/5 Yes a 10 out of 5. Fluval filters are amazing.Suction power: 5/5Easy to clean: 5/5Noise level: 5/5=====================Helpful, is how I hope you find my review

Ich selbst habe jetzt schon den zweiten Fluval U2 für mein 60 lt. Aquarium in Gebrauch und finde ihn wirklich gut. Er filtert das Wasser schön sauber und meinen Fischen geht es gut. Der Filter ist unschlagbar leicht zu reinigen: Einfach nach vorne klappen, Deckel öffnen und die drei Filterpatronen entnehmen. Unter lauwarmen Wasser oder im abgesaugten Aquarienwasser ausspülen, wieder einsetzen, fertig. Einfacher und bequemer geht's nicht. :-) Ich selbst reinige auch alle 1-2 Monate den Antriebsmagneten. Auch das ist sehr einfach: Boden abziehen, Antriebsmagnet entnehmen, säubern, Halterung von Mulm befreien, fertig. Bei diesem Filter müssen keine Schläuche oder ähnliches aufwenig durchspült und gereinigt werden, der Filter ist in 10 min. gesäubert.Ich hatte den ersten Filter knapp 2,5 Jahre in Gebrauch. Erst im letzten Vierteljahr fing der Motor etwas zu schwächeln an: Er schaffte es nicht mehr, Luft für die zusätzliche Belüftung des Beckens anzusaugen, die Filterwirkung war jedoch immer noch ausreichend. Trotzdem kaufte ich jetzt einen neuen Filter, um evtl. Problemen während der Urlaubszeit vorzubeugen. Den alten Filter habe ich als Ersatzfilter behalten. Die Filterpatronen mußte ich bisher nie austauschen. Wenn man sie regelmäßig ausspült, funktionieren sie einwandfrei.Lt. Fluval folgende Fiilterwartung empfohlen:"Filterpatronenaustausch alle 3-6 mon., Antriebsmagnet jährlich tauschen. Filterreinigung: Einmal pro Jahr". Nun ja...Klar, nach 3-6 mon. ist der Schaumstoff der Patronen komplett dicht. ;-) Wenn ich jedoch den Filter einmal pro Monat säubere und die Filterpatronen beim regelmäßigen 2-3-wöchigem Wasserwechsel ausspüle (!!!), ebenso den Antriebsmagneten reinige, dann kann ich mir das Geld für den empfohlenen Ausstausch sparen. ;-) Auch habe ich so meine Zweifel, das der Antriebsmagnet 1 Jahr (!!!) ohne mal gereinigt zu werden durchhält. Klar, daß der Motor dann auch schneller kaputtgeht...Ich gehe davon aus, daß der Filter bei guter Pflege wieder seine 2-3 Jahre problemlos seine Arbeit verrichtet. Und dann werde ich mir auch den 3. Fluval U2 kaufen.

Wir haben ein kleines 60L Becken und hatten nur einen schwachen Filter dabei.Dieser hat auch endgültig seinen Geist aufgegeben.Ein neuer, guter und günstiger Filter musste her.Dieser hier hatte viele gute Bewertungen und der Preis schien auch sehr verlockend. Der Hersteller hat ohnehin einen guten Ruf.Der Filter ist etwas größer als unser alter, doch stört er auch bei kleinen Becken nicht.Dadruch, dass der alte Filter kaputt war , wurde das Wasser immer schmutziger. Der Boden war ziemlich drecking.Der Einbau war am Abend und dann am nächsten Morgen war ich begeistert. Das Wasser glasklar, der Boden komplett sauber O.O TOP!Das meiste wurde hier ausführlich beschrieben, also nur kurz meine highlights:+ leichte Montage+ nur noch alle 2-3 Wochen Wasserwechsel nötig (vorher war es nach 1 Woche aller höchste Eisenbahn)+ leise+ 3 Einstellmöglichkeiten (3 Düsen und jeweils in der Stärke regelbar)+ Das Becken hat nun eine hervorragende Wasserbewegung+ Luftventiel, dadruch sprudelt es. (dann allerdings deutlich hörbar)- bis jetzt nichts negativesKann ich jedem Aquariumbesitzer mit kleinen Becken empfehlen.GrußDW
