SunSun HW-704B Aquarium External Canister Filter 2000l/h UVc 4-Stages

The particular strength of the external aquarium filter is that there is little space wasted inside the aquarium. An external aquarium filter can be easily placed under or next to the pool. For an optimal positioning the hose connections on top of the lid are rotatable at 360°. The large container volume ensures a cleaning with very large filter volume. There is enough space for various filter media.The SunSun Aquarium External Filter HW-704 B can be easily connected to aquariums with a water volume of up to 1000 litres. So, the operation of large-sized aquariums becomes a simple exercise. The pump capacity is 2000 litres per hour. The external aquarium filter provides for a high flow rate, however it operates quietly. The rubber stands provide for an optimal vibration reduction.The super quiet aquarium filter technique of the SunSun HW-404 external aquarium filter is suitable not only for freshwater aquariums but also saltwater aquariums.The aquarium filter is delivered with filter media for the four filter stages. The filter baskets with their useful handles can be filled individually with the filter media. In this respect, please note that the filter media is graded from coarse to fine. The overhead 1st filter stage, the so-called pre-filter retains coarse dirt efficiently and extends considerably the service life of the biological acting filter material that is located on the underlying filter levels.Filter Media:The delivered filter material is considered a standard equipment for your external aquarium filter.Basically, it applies from bottom to the top:1st stage: mechanical/biological filtration in part2nd stage: biological filtration 3rd stage: chemical filtration (activated carbon, turf, phosphate Ex etc.) As for 4-stages filters, you can extend by a mechanical or biological filter stage, depending on the filtering requirements. Ceramic RingsCeramic glass rings for the internal and external aquarium filters. The filter media, with mechanical filtration, are used for removing suspended particles. The ceramic rings cause a water turbulence in the filter basket due to their special form and large surface. By this way floating particles can accumulate during the descent and coarse dirt particles are removed from the water cycle.This filter material creates optimal conditions for filter bacteria which reduce nitrite peaks better than other filter materials. Filter Floss – Filter FleeceFilter media like fleece, floss or sponges are essential in modern aquaristics.Coarse dirt particles are absorbed by means of filter floss, sponges reduce the nitrate, clean the water of chemical impurities and provide ideal conditions for the settlement of filter bacteria.Bio BallsBio balls are used in aquaristics as mechanical and biological filter media. These balls offer bacteria a large area for their accumulation and are considered to be high performance filter media for powerful filter systems. In contrast to other filter media, bio balls have a virtually unlimited life span which makes them a popular and cheap filter medium for pond filter systems, trickle filters and chamber filters. Activated Carbon – optionalActivated carbon is used in aquaristics to filtrate urinary and humic substances, pesticides, toxins, and similar residues and to provide for clean aquarium water. Additionally, the ozone and the chlorine content of the water is reduced through the use of the activated carbon.The activated carbon is particularly suitable for the pre-treatment of tap water, for water clouded with suspended particles and for filtering out residues after a medication treatment.During a medication and algae treatment one should not use the activated carbon. However, after said water treatment the activated carbon is indispensable for removing remnants.We do not recommend leaving the activated carbon in the filter tray over a long period. After the media filter (activated carbon) reaches its absorption capacity, there is the possibility that absorbed harmful substances are washed out and end up in the aquarium water.When purchasing a new aquarium filter or after a complete cleaning, the beneficial bacteria must be enriched again. There are special bacteria cultures that can be added to the aquarium filter, thus facilitating the start.The Highlight of HW-704 B is the integrated UVC unit.The flow of water within the aquarium filter makes that the water first passes a UVC Clarifier unit. Due to the UVC radiation of said UV-lamp harmful algae, bacteria and germs are destroyed, and the algae formation...
