Fluval U2 Underwater Aquarium Filter 110 Litre (30 US Gal)

Product Information

If your filter fits into the rear corner you may not want a water flow that is only unidirectional. Having the option of being able to direct the flow left to right and/or up and down gives greater flexibilty and is a function easily achieved by the manufacturer at little cost. For alternate cleaning. If sponge is the only media available for your internal filter it is tasked with performing the roles of both mechanical and biological filtering. The sponge needs frequent cleaning, yet cleaning risks the bacteria colony. The solution is two sponges, so that they can be cleaned alternately, or even replaced alternately, and the bacteria remains intact. In addition, Fluval U Filters offer installation versatility: they can be installed vertically against the aquarium wall to create currents or customized flow patterns; or they can be placed horizontally in shallow water tanks or to create decorative features such as waterfalls. Carbon inserts have visible benefits as they remove dyes from water, odours and traces of medications. They remove chlorine too. But, for me, the best media option of all is extra biological media. As with the double sponge scenario, one doing the mechanical filtering and leaving the other to do the biological filtering, is better than one media that is tasked to do two jobs. In my book, extra biological means a better filter. It can be used as a lone filter or with other filters for extra filtration and water movement like I use it. Mine has been running for about 7 months now and it is still as strong as ever and continues to be completely silent. It has 3-stage filtration with foams, BioMax rings and Carbon included as standard. You can find replacements for these relatively easily either from your LFS or online.

In terms of features this filter has a three-way flow, offering water flow from the top outlet, the bottom outlet or the built- in, vertically-mounted spraybar in the middle. The flow from the top and bottom outlet is directionally controllable, and a Venturi is supplied.Fluval U Underwater Filter provides complete and efficient 3-stage filtrationto create superior aquarium water quality. All models come with a Bio-Foam filter pad to remove large particles. The larger 2 sizes also include a Poly-Carb pad to assist with removal of fine particles, chemicals and odours. They also have the addition of Biomax filter nodes to assist with biological filtration. Anpassbare 3-Wege-Durchflusskontrolle: oberer Auslass für Umwälzung und Sauerstoffanreicherung, integriertes Düsenstrahlrohr für einen sanften, gleichmäßigen Durchfluss und unterer Auslass für eine Wasserbewegung am Boden des Aquariums

During the test I was still in the early stages of setting up my fish house. This put me in the convenient position of having nine 24” tanks available in which to test filters, with seven containing no fish — so I would do two batches of tests, seven at a time. Offering outstanding 3-stage filtration, with increased water movement and vital aeration, Fluval U-Series internal filters are the perfect solution where external filtration is not possible. The Fluval brand (by Hagen) has become one of the most well known names amongst fish keepers and it is for good reason. For many years now they have provided one of the highest, if not the highest level of quality when it comes to aquariums, filters and other accessories fish keepers have come to know over time. They have expanded their range over time but the quality has stayed the same. Internal filters are the most popular type of filter on the market, with the biggest choice of models and probably the most varied group of people using them — from beginners to nano owners to quarantiners to big cichlid and oddball keepers. Internal filters are readily available and have to cope with a huge range of situations. What I want from any internal is versatility and reliability, as they are often the only form of filtration used in the aquarium. A simple media upgrade is the polyester pad, though with some models it appears to be more about selling the pads as a disposable and hence replacable item more than it actually appears to benefit.Large pallet items like aquariums are deemed delivered successfully with no damage once the the driver has left the property. If a report of damage is submitted after the driver has left we may be unable to assist with replacements. We recommend refusing a damaged delivery, this is the fastest resolution. Fluval U Series Underwater Filters provide complete and efficient 3-stage filtration, including BIOMAX biological filtering, to create superior aquarium water quality. Not much really, other than the flip-top was a bit stiff on our new model and impeller access isn’t as accessible as it was on the previous Fluval plus model.
