The particular strength of the aquarium external filter is that there is little space wasted inside the aquarium. An aquarium external 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-402 B with UVC-unit can be easily connected to aquariums with a water volume of up to 400 liters. So the operation of large-sized aquariums becomes an simple excercise. The pump capacity is 1000 liters per hour. The aquarium external filter provides for a high flow rate, however it operates quietly. The rubber stands provide for a optimal vibration reduction.
The super quiet aquarium filter technique of the SunSun HW-402B aquarium external filter is suitable not only for freshwater aquariums but also saltwater aquariums.
The aquarium filter is delivered with filter media for the three filter stages. The filter baskets with their practicle 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 aquarium external filter.
Basically, it applies from bottom to the top:
1.stage: mechanical / biological filtration in part
2.stage: biological filtration
3.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 Rings
Ceramic 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 turbulance 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 Fleece
Filter 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 Balls
Bio balls are used in aquaristics as mechanical and biological filter mediat. 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 – optional
Activated 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 to leave 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-402B is the integraged UVC-unit.
The water flow within the aquarium filter makes that in the water first passes the UVC-clarifier unit. Due to the UVC-radiation of the UV-lamp, all harmful algae, bacteria and germs are destroyed and the algae formation remains under control.
Normally, the UVC-clarifier provides for clear aquarium water within a short period of time. You achieve the best results with this combination of an UVC-clarifier an a biological aquarium filter.
UVC-pond clarifiers irradiate the water in a flow-through reactor with UV rays.The UV-C radiation destroys the swimmig algae. The algae agglutinate to large particles and ca be easily removed by means of mechanical filtering.
Our UVC clarifiers modify the tertiary and the quaternary structure of the algae proteins by means of UV-radiation. This means the destructions of the algae which can be removed from the water by aquarium filters.
The life span of the UVC-light source varies between 7.000 and 10.000 operating hours. We recommend to change the light source and to clean the quartz glass of the UV-lamp each year.
The flowing water is purged of harmful bacteria and germs. The reduction of germs has no negative effect on the aquarium’s microclimate because bacteria settle themselves on stones, the filtration surface and in the whole aquarium system for reducing pollutants and they can reproduce themselves. The UV-lamp can maintain the total microbial content of the aquarium water in near -natural proportions.
Ocasionally you can hear the argument a UVC-clarifier is unnatural. Although this is right in principle, the statement is not convincing as a counter-argument, because from this point of view every aquarium filter or the whole aquarium is “unnatural”. Fish kept with a clarifier are said to grow soft and fall ill immediately after being put into other water. Firstly, that is not true, and secondly it could also be argued that a biological aquarium filter is harmful and a a relatively high nitrite content would contribute to the fish’s strengthening. Quite the opposite. In fact a UVC-clarifier helps balancing the natural biotope of the aquarium environment.
After the insertion of the filter media, the aquarium external filter is filled with water. SunSun offers an excellent comfort, the ergonomic pump cylinder on the top of the external filter. For the filling of the filter container – and without irritating suction intake – you simply press the pump cylinder for several times. So the aquarium filter fills up with water caused by every pumping motion
The multi-function valve on the pump head has a quickly disconnecting coupling which separates the hoses from the filter container without emptying it before. The safety hose adapters on the valve, that are easy to lock, provide a high level of seccurity against leakage. The flow rate is regulated by the multi-function valve.
The return hose is led into a clean bucket that is installed below the external filter.
To vent the external filter, the maximum possible flow rate must be adjusted. The manual pump is to be operated until there are no more air bubbles. Thereafter the filled hose is to be closed with one finger und re-installed on the return-piping on the edge of the aquarium.
Before the first operation, the filter materials have to be removed from their packaging.
There must always be introduced only ONE cotton at the same time in the filter.
