Fluval U2 Filter Media - Poly/Clearmax Cartridge, 2-pack.

Product Information

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. 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. 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. It is strongly recommended to dispose of carbon monthly or immediately after it has effectively accomplished a specific requirement, such as the removal of medication after a treatment, clearing of an odour, cloudy water, etc. BIOLOGICAL 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.

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.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. Water quality starts with effective biological filtration. The basic requirement is filter media that is porous and offers a large surface area. It is equally important to remember that nitrifying bacteria that provide this all-important aquatic function are aerobic (oxygen-loving bacteria), therefore, you want the filter output to move and break the water’s surface. 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.

So, let’s consider the basic types of water filtration as well as the types of filter media best suited for the job. FILTRATION – 3 BASICS TYPES MECHANICAL 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. 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. 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. Stage 3 consist of the bio max ceramic media designed for colonising filter bacteria all part of the biological filtration. These should be change in rotation to the foam media every 6 months.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. 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.
