Sunsun 302 NON UV Canister filter 1000 LPH no media

A great advantage of the aquarium external filter is that space is not wasted inside the aquarium. An aquarium external filter can easily be placed under or next to the aquarium. For an optimal positioning the hose connections on top of the cover 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-302 can easily be connected to aquariums with a water volume of up to 400 liters. So the handling of large-sized aquariums is easy. The pump capacity is 1000 liters per hour. The aquarium external filter provides a high flow rate, however it works quietly. The rubber stands provide an optimal vibration damping.

The super quiet aquarium filter technique of the SunSun HW-302 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 practical handles can be filled individually with the filter material. In this respect, please note that the filter material must be graded from coarse to fine. The above lying 1st filter stage, the so-called pre-filter retains coarse dirt efficiently and extends considerably the service life of the biological working filter material that is inserted in the filter stages beneath.

When purchasing a new aquarium filter or after a complete cleaning, the helpful bacteria must accumulate again. 
There are special bacterial working stocks that can be added to the aquarium filter, thus facilitating the start.

Operation:
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. 

Cleaning:
The multi-function valve on the pump head has a quick disconnect 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 security against leakage. The flow rate is regulated by the multi-function valve.

Ventilation
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 has to be operated until there are no more air bubbles. Thereafter the filled hose is to be closed with one finger and to be re-installed on the return-piping on the edge of the aquarium.

Note: 
Before the first operation the packaging of the filter materials has to be removed.
Be aware that only ONE wadding can be inserted into the filter at the same time.
