Great filter – love it
I have the c4.It’s great and I have been in the hobby for over 30 years.I am using it on a 20 gallon tank.You can never have too much flow rate.To slow the turbulence I use a Fluval Edge prefilter, the flow adjuster and an aquaclear 50 foam sponge at the water output.Let me comment on a few negatives people have written about this filter.1) The water in my tank is crystal clear and as Jack Nicholson and Tom Cruise said in “A Few Good Men” ….”It’s that simple.” “Are we clear?” “Yes, sir.” “ARE WE CLEAR!?” “Crystal” ….. LOL,love that movie.To those who said the water is cloudy, yes, it was at first. I think it was because of the C nodes. You need to either rinse it clear for hours before using it or just let the filter do it in the tank. It took about 2-3 days to clear up but once it did, the water in my tank is crystal clear. I have been running it for 2 weeks and without the charcoal. I replace it with the aquaclear Biomax to increase the biological media. The Biomax and C nodes’ fine powder dust clouded the water but like I said, it’s clear crystal clear now. Just let the filter do it’s job and the water will be crystal clear in a couple of days.2) My filter is so quiet that you don’t know it’s on. What I did was apply some vaseline onto the impeller shaft and into the hole of the impeller. I did this without hearing if it needed to or not. I just applied it before I used it. The motor has NO noise at all and the lid does not rattle. The only thing you hear is the water cascading out of the filter.3) The self priming issue is that you need to fill the filter box with water before you start it. Once it is filled with water, it will self primes when you plug it in. It will take about a minute to self prime as it sucks up the water through the siphon tube. To help the self prime and make it more efficient, I clogged the hole on top of the U intake tube. Now when you unplug the filter and replug it it starts right up without it needing to refill (self prime) the intake tube. If you do a water change and the water in the tank falls just above the bottom of the U intake tube inside the filter box you will need to refill the filter box otherwise it won’t self prime. So add water into the box when you refill your tank and when you replug your filter, it will self prime.4) Try to buy the larger filter (C4) if you can. You can always change the impeller to the smaller impeller if you feel the flow it too much or modify it like I did with prefilter sponge and aquaclear 50 foam. With the bigger filter, it’ll clean more and hold more beneficial bateria. And if and when you upgrade your tank, you won’t need to buy a new filter. The impellers for the fluval C series and aquaclear are the same. Matter of fact, the motors are the same for all fluval C series and aquaclear except for the 110 model. It’s the impeller that determines the flow rate and they are interchangeable between models and sizes except the 110.All the positives you’ve read about this filter is true.It’s easy to clean, the red tab that notifies you that your filter foam needs cleaning is great; you are not stuck with any proprietary media which usually cost a lot more to replace; the foam pad and bio media DO NOT need to be replaced – just rinse the foam pad or bio media in used or dechlorinated water. They should last for several years. If you use activated carbon/charcoal which I don’t, you’ll need to replace them every so often depending on your tank load. You can buy any brand of activated carbon and put it into a nylon bag and it’s save you money.Try to use a prefilter. It’s attached to the bottom of the intake tube. It helps to catch the debris and uneaten food before it goes to the foam pad keeping it cleaner. It’ll also increase your beneficial bacteria load and your fish will love to peck on it for the uneaten food. The only thing is that you’ll need to rinse it once in a while or it will clog up completely and slow the filter down to a trickle. Just rinse it when you do your water change.Hope this helps…..may your fishes be happy and healthyUpdate: Feb 22, 2013. The filter is still going strong. The reading of the water has been 0 ammonia, 0 nitrite, and 5 nitrate with weekly water changes. It would probably be the same with a water change every other week. And this is in a very overstocked aquarium. The only thing I need to do is rinsed the prefilter with every water change or it will clog up and restrict the water flow to a trickle and the water to the trickle part of the filter will not get any water. That’s how good the prefilter is in catching the debris and keeping the foam and biomax clean. The red tab pop up device has never moved and when I check the foam it is very clean but I do rinsed the foam every 3 months and LIGHTLY rinse/shake the biomax every 6 months in used aquarium water. DO NOT buy NEW foam or biomax. Just rinse them. They will last several years if not forever especially if you use a prefilter and the prefilter does not need to be changed just rinsed also. I had to clean the impeller just recently since it wouldn’t start back up/spin. It had a lot of slime. I just rinsed off the slime from the impeller and shaft and reapplied some vaseline and it was of and running like new. The water is crystal clear also.Update: Jan 13, 2015. The filter is still going strong. Still quiet as when I first bought it. I have upgraded my tank to 25 gallons and it’s still working like a charm. I have not bought any replacements, just rinsed the prefilters, pads, biomax, c nodes and impeller. My readings are still 0 ammonia, 0 nitrite, and 5 nitrate and I’m changing my water once a month and sometimes once every two months (getting lazy). This is a great filter.Updated…. Feb 22, 2016. The filter is till going strong. Quiet as when it was new. I did replace the form as it was wearing down from squeezing it when I clean it. All the bio medias are still in good and hasn’t broken down. M water reading are the same. Changing water less frequent. Getting lazy because of the good water quality from the filter but not good for the fish which needs the minerals from new water and removal of nitrates.Update…..2/6/2019. The filter is still going strong. Have not replaced any parts except for the foam that i mentioned before. The motor is still quiet and pumping like new. The biomedia are still intach and have not broken down. I have not been as diligent in chaging the water as before. Been changing the water about every three months and the numbers still reading 0,0,5. Upgrading the biomedia and using the C4 will do wonders for your aquarium and ease maintenance care.

Decent product
I purchased this filter a month ago. It is installed on a Marineland 60 gal. cube. The aquarium is a Corner- Flo and already has a Fluval 360 installed. The water in the tank was not as crystal as I would like and I think the Corner_Flo option may be impeding the canister a bit. The tank has African Peacocks and Haps in it. They do make a mess. Not wanting to put another canister in the already crowded cabinet. I opted for an HOB filter. I wanted one that was simple to clean and maintain. I looked at the AC’s, Fluval C series and the Eheim Liberty series. This one fit the bill for me. All three filters can use “Bulk Media”. A requirement for me. (hate cart’s and premade foams $$$$$$) Of the original media I only used the the white foam and polyester pad filter and the small pad on the wet dry filter. It took about a week before the main filter pad was starting to clog (red indicator floating) I rinsed it and it lasted about another week. The poly pad on the back is the culprit and they do make the foam with out it. But for me I just decided to toss it and I cut some blue bonded filter material and installed it.. I also put polyester floss in where the carbon would go as I do not use carbon. In the wet dry bio holder. I put Seachem Matrix instead of the ceramic nodes.. Also many reviews on the web state that they do not use the little white pad on top of the wet dry filter. Bad move as the water that comes from the spout has not actually been through the main filter. It is tank water straight from the pump and the debris will clog your bio media. I plan to put some thin foam or polyester there when the original is bad.Overall this filter has been good. The water is much clearer now. The output is designed so that you do not get the “water noise” that some HOB’s have. (Unless you let your water level drop a ways.) The filter has some noise on start up. It has started to diminish as it runs (slime build up in the pump). I did some research on this and it is common. If the amount of noise (what little there is, way less than an air pump) is unacceptable, the application of vaseline or silicone grease to the impeller shaft usually fixes the problem. This filter also has a wide resting area for the tank brim. A good deal for a tank with a frame but not so good with a frameless tank. The problem is in the leveler. The design of the leveler is the same as the AC’s. Both are made by Hagen. The leveler is a snug fit in its hole. However with a frameless tank the tallest leg must be used in order to level the filter. The problem is that if the leg is not completely square with the tank surface. Any pressure applied to the filter during maintenance causes the leveler to “cam or twist”. As the filter is heavy when full of water it moves pretty abruptly when this happens. One could use a block of some sort between the tank and leveler so that a shorter leg could be used which would stop the twisting issue.All in all I like this filter. Have already purchased another and would recommend it .

Dieser Filter läuft wie es soll. Nur der Motor ist etwas zu gut hörbar.Sonst. Gibt es nichts zu beanstanden. Strömung ist mehr als ausreichend. Würde ihn nochmal kaufen.

I bought this filter for my 40 gallon tank. It was noisy right out of the box. I tried leveling it and checked the impeller to make sure it was seated properly, but it still had a vibration and rattle. I contacted the seller and he sent me a new impeller and that fixed the problem. By the way, excellent service and very speedy, did not leave me hanging and waiting. Now on to the filter, this is one of the best hang on filters I’ve had in 40 some years of fish keeping, it is quiet and does a beautiful job keeping my tank sparkling clean. The 5 stage filter system is great and the filter looks awesome on the tank. I could go into lengthy details about the filter but just read the info on it, it’s all true what the manufacturer says. It just does what it’s supposed to do, period. It has a 2 year warranty so you can buy with peace of mind. Unlike some other filters, you can buy any and all replacement parts for this filter at reasonable prices, so chances are this filter will last you a lifetime. I have used Hagen products for 40+ years and they stand behind their products, no ifs ands or buts. So if you are looking for a filter that is (IMHO) one of, if not, the best on the market today, this is the one for you.Peace and happy fish keeping 🙂

For started Amazon royally messed up with this one – the item is shipped with an EU plug so bear this in mind.Disregard most reviews on here, the filter when set up correctly is near silent.English instructions are available the Fluval website but basically it’s important to fill the filter with water before turning it on. Then after the filter gets rid of any air it runs near silent and is barely noticeable.The filter looks great and all media can be replaced whilst it’s running which is a bonus. The trickle feed is brilliant and exactly what I needed for a betta aquarium which doesn’t need a lot of water flow.

Diciamo subito, che un filtro per acquario a zainetto, per quanto grosso sia non avrà mai una resa di un filtro esterno. Questo filtro a zainetto, ne ho provati altri, invece è molto equilibrato, potente, silenzioso (almeno per ora), ed ha un giro di acqua al suo interno, ottimo. Io al posto della busta del carbone attivo, ho tolto anche la capsula di plastica rossa, ho inserito a capienza i cannolicchi in calza di nylon, con al di sopra l’ovatta e sopra il suo cestellino, con gli altri cannolicchi in dotazione, per aumentare l’accumulo dei batteri buoni, che non sono mai abbastanza. Ne ho acquistati 2 per due acquari da 40 litrei l’uno, perchè mi piace che l’acqua in superfice sia adeguatamente mossa, per non creare patine oleose eventuali. Logicamente se allestissi un acquario con i Betta splendens questo filtro sarebbe troppo potente, non va bene, a tal proposito, si può regolare un minimo la potenza di uscita dell’acqua, riducendola un pochino. Con il tempo non so se diventerà rumoroso… vedremo, ma per ora sono molto soddisfatto. Consegna Ok, come sempre, servizio Prime, on TOP !

Tengo un acuario de 80 litros con 4 peces cometa de un año. Anteriormente tenía un filtro interior de otra marca con muchísimos problemas de eficacia, ya que no limpiaba lo suficiente y cada semana debía renovar una parte de agua y limpiar.Compré el producto filtro fluval C4 y me vino un primer envío, el producto era completamente nuevo pero tenía una esquina del filtro con un pequeño roto. Pedí el cambio y en 24 h me lo reemplazaron por otro filtro completamente nuevo en condiciones perfectas y rapidísimo. Sin queja ninguna. Servicio excelente.Lo coloqué y comenzó a funcionar, lo tengo aproximadamente un mes. El cambio ha sido fantástico. El filtro funciona perfecto. A los 2 días de funcionar ya tenía el agua limpia, cristalina, transparente, y así la tengo desde entonces.El aparato mide aprox. 21,5 centímetros (cm) de ancho, por 16 cm de profundidad total y de altura total mide 22 cm de altura (sin contar el tubo de captación).La mochila sobresale por detrás o lateral 10 cm respecto del acuarioDe altura sobresale del acuario 7 cm por arriba.El tubo de captación de agua yo lo tengo a 25 cm de profundidad por debajo de la cota de agua. Puede llegar un poco más. Es regulable en altura, se puede bajar o subir y con ranuras en la captación para evitar que entren partículas grandes.No hace prácticamente ruido, sólo el ruido propio de un pequeño aparato, que casi ni se nota, y es completamente normal. Y además lo que se oye es el tranquilizador y relajante sonido del agua al caer por la cascada.Ya lo que es el filtro tiene primero el filtro C esponja o foamex o poliester, el carbón activo, una tela filtrante, las cánulas cerámicas o vidrio, y el agua vuelve a verterse por la cascada. Creo que es un filtrado completo.Se limpia fácilmente, cada 2 semanas retiro los filtros, los enjuago en un recipiente con la propia agua, y los vuelvo a poner, muy fácil.Tiene 2 velocidades, se regula con una palanca parte superior a izquierda, yo lo tengo al mínimo y es suficiente. Algún rato lo pongo al máximo pero casi nunca. Esta palanca no regula la potencia del motor de extracción, parece que sólo regula la entrada de captación de agua, pero el sistema yo lo veo bien.Tiene un pivote rojo, arriba a derecha, que sube cuando está sucio. Pero a mi no me ha subido nunca.El autocebado, con el nivel de agua de acuario alto, he comprobado que desconectando unos minutos la corriente eléctrica, y volviéndolo a enchufar, el mismo se autoceba y vuelve a extraer agua y bombearla. Quizás si pasa más rato, y el nivel del agua del acuario es muy bajo, el filtro perdería agua acumulada y podría no funcionar.Algo en contra, que no tiene esquimer de recogida de residuos superficial. Pero creo el sistema como está es suficiente.Por tanto, es eficaz filtra y limpia perfectamente, gran calidad, silencioso, calidad precio buena, totalmente recomendable.
