Fluval U2 Internal Aquarium Filter – Up to 110 Litre Fish Tanks, 400 L/H Adjustable Flow, 3-Stage Filtration with BioMax, Freshwater, Marine & Reptile Use

Best in tank filter I’ve had. Bought as original tank filter went down in my 130l , the pros of this filter are - -super quite , hardly any noise -smart looking / blends in / fits nicely -3 different spray modes (top , bottom or middle for gentle flow) So easy to use / setup and for maintenance The water is really really clear with the active carbon in the filter , it comes with ceramic media too which is a bonus Overall really good filter , highly recommend this in tank instead of external canister

We bought this as the filter we had was not doing a great job water was never crystal clear. Bought the u2 and over night the water was clear. The pictures added to this review are from this weekends water change/aqua scaping. The water got super cloudy due moving the sand about. With in a few hour a noticeable difference. This morning the tank was crystal clear. Out water is dark due to new wood tanens being in the water. But the water its self is beautifully clear. Quiet filter and easy to use. It is quite a big filter. We have ours hidden behind some wood. The three settings for bottom middle or top flow is great to have. Easily removed for filter changes. I cant recommend high enough. You can feel the quality. If you order this get a eu to uk convertor plug as mine came as an eu plug and not a uk one. Wasnt an expensive add. Even that doesn’t take away for how great the filter is

Brought to replace a failing one. I find these last a few years and then start failing. I like this filter, it is quiet and does the job well. Needs cleaning about every 2 weeks in my 100L tank.

Good item keeps tank clean

TOTAL RIP OFF. DONT BUY AS IT IS AN AMERICAN PLUG WHICH DOENT RUN ON 240V, US RUNS OFF OF 120V I BOUGHT AN ADAPTER FOR US PLUG BUT THE FILTER BURNT OUT AND IS NOW BROKEN DONT GET RIPPED OFF LIKE I DID, SAVE UR MONEY & GO TO SHOP, OTHERWISE U WILL REGRET BUYING IT

I recently upgraded to the Fluval U2 Underwater Filter after using the standard filter that came with my Pets at Home LoveFish tank, and the difference is huge. The old filter felt like a gentle trickle in comparison. This one actually moves the water properly and keeps it clean and clear. The Fluval has three flow settings depending on what you need, top, bottom, or full middle. I personally use the top outlet with the nozzle angled towards the surface. This keeps the surface water moving and means I no longer need to run a separate air pump. There’s less tubing in the tank, far less noise, and lower power use overall. I’ve been running it for about a month now with no issues at all. It’s easy to maintain, runs quietly, and feels well made. I’m using it in a 64L tank with shrimp, tetras, and snails, and the flow is just right, strong enough for good circulation but gentle enough for smaller fish and shrimp. I got it for £40.50 it’s great value for what you get, especially compared to the basic filters that come with starter tanks. If you’re still using one of those, this is a solid upgrade that makes a big difference to water clarity and general tank health.

Bought to replace a JBL CristalProfi on the strentgh of other reviews on here. It's being used on a Fluval Roma 125l tank, which in theory this U4 filter should be more than enough to handle. Whilst installing and cleaning is straight forward and inexpensive (replacement filters are cheap and easy to come by), I've been disappointed with the water clarity of the tank, despite regular water changes. Using on the middle or bottom filter settings the tank clouded up relatively quickly, so I've always had to use on the top and most powerful setting. More recently the filter completely stopped and needed a jolt to get it running again. Whilst it does an OK job my previous JBL filter produced clearer water and for longer, but was more time consuming to replace the filters and media. Will look into upgrading to an external filter next time.

Really good filter. I've been having it for years now and honestly im really happy with it. Im using it in a 90L tank, works great, not too strong water flow, which is good for my lazy fish. Its easy to assemble and clean, quiet (especially if fully submerged) and not too heavy. There's no smell from it if cleaned properly

Acquistato in sostituzione del filtro integrato del mio Askoll Pure XL 94 litri. Con i pesci Oranda, che sporcano moltissimo, il filtro integrato nel coperchio non era sufficiente a garantire una buona filtrazione. L’acqua era sempre torbida e piena di impurità. In più il precedente, essendo integrato nel coperchio di plastica, era estremamente rumoroso. Questo Fluval è incredibile. Estremamente silenzioso, arriva completo di tutti materiali filtranti, ha l’uscita del flusso regolabile: - uscita dal basso - uscita centrale più distribuita - uscita dall’alto con valvola Venturi per l’ossigenazione (più rumorosa per via delle bollicine) Tutti i problemi di sporcizia nell’acqua si sono risolti nel giro di due giorni. In più la manutenzione sembra semplicissima in quanto il filtro è apribile dall’alto e i materiali sono facilmente estraibili. Consiglio a chiunque cerchi un filtro estremamente silenzioso ed efficace con un’ottima portata d’acqua senza necessariamente creare troppe correnti. Prezzo più che adeguato.

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!

I had a cloudy aquarium with a filter priced 400 rs. It had to run for a week to make the water clear and the water flow was strong which made the fish hard to swim on their own. But this filter does magic. With in some hours after installation, the water became crystal clear. The flow is very smooth too.

Zeer stille pomp. Filtert erg goed. De aquarium opnieuw ingericht water was rommelig geworden met drie kwartier weer geheel helder.

it worked flawless for 20 months and stopped working. I dont know how long is the warranty on it.
