About this deal

Different filter media exist for varied purposes. For example, for removing an odour or improving water clarity, carbon would be your typical choice.

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. 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. Stage 1 consists of a Foam pad which is designed remove large particles from the water all part of the mechanical filtration. These foam pads should be replaced every 6 months. For the health and survival of your fish you will want to ensure there is strong biological filtration present, and in this case you could use Fluval BioMax and/or Fluval Bio-Foam. 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.

The Fluval U2, U3 and U4 Internal filter have an adjustable flow to ensure the filter meets the needs for different aquarium environments, this consists of 3 flow settings. Top output for increased circulation and oxygenation, spray bar for a gentle flow designed for planted aquariums and the bottom output designed for deep water circulation.

The U series internal filter range are an efficient reliable filter designed as the primary filter for smaller aquariums or a supplementary for larger aquariums. The Fluval U2 can be situated either vertically or horizontally which means this is perfect for both deep and shallow water aquariums such as turtle tanks. It has a lot to do with keeping water clear and your aquarium clean. Fish, plants, and some natural decor all contribute some physical waste to your aquarium. Mechanical filtration takes care of trapping unwanted debris. 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. This form of filtration occurs when natural living bacteria converts the biological waste created by fish and other organisms in an aquarium into a form other bacteria use and remove from the water.

Bio-media does clog over time, and it is recommended to provide clean filter media for effective colonization by bacteria. This family of nitrifying bacteria will benefit from partial media changes every 3-6 months to ensure clean porous surfaces are available. Regular cleaning and replacement of mechanical media, such as foam, also promote better conditions for the growth and prosperity of these beneficial bacteria.Remember, your aquarium filter will best support your aquarium when it is properly maintained. As we have pointed out above, filter media defines the capability of your filter. Just like the tools in the hands of a skilled mechanic, your filter is one of the most important tools for ensuring you have a well-tuned and healthy aquarium. FLUVAL TV Your filter should be used to its full potential by ensuring its output is aggressively moving the surface of the water since this is how you increase the dissolved oxygen content in water. The by-products of the biological waste are known as nitrogenous waste, which can be ultra toxic depending on the pH and concentration. The aerobic bacteria that perform this essential filtration prefer filter media in filters to colonize due to the dimmer or light-free conditions within. Also favourable to them is the strong supply of dissolved oxygen provided by the actual water flow through the filter. 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. Carbon is manufactured from an extremely important raw material that directly impacts water filtration capability. Fluval Carbon is made from bituminous coal – the best source material for carbon that is used for water filtration.

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. Filter media is the core of what a filter does and how well it is going to actually filter aquarium water. The media content of your filter represents its filtration capacity. Simply put, your filter is the vessel that makes changing and maintaining filter media convenient, and it facilitates continuous and effective water flow through the media. Internal Filters are an excellent option for small to medium sized aquaria. They are simple and easy to set up, they sit just inside the aquarium itself meaning they can be easily installed into any fish tank, with no troublesome pipes and hoses. They will also work well as a powerhead for water circulation, with the added bonus of the extra filtration. It is worth noting that you should clean your filters impellor every couple of weeks to ensure it is functioning normally and keeping the water moving around the tank. U series underwater filters offer superior water purification, movement and aeration capabilities and have been designed for use in both fresh and saltwater applications. 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.

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. 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. The most common and versatile mechanical filter media is foam. Cell size can vary in foam so accordingly so does the size of waste it removes. The smaller the cell size the finer the debris it can immediately remove. Foam also has good capacity, making it very capable of handling large waste loads. While foam can be rinsed and re-used many times to ensure its effectiveness, it is strongly recommended to replace it at least twice a year. As it ages in water, it becomes increasingly difficult to rinse thoroughly and may start to wear and break down. CHEMICAL
