SunSun Aquarium Internal Aquarium Pump 300l/h2W for 40l Fish Tank HJ-311B Filter

The SunSun HJ-311B aquarium internal filter combines an aquarium filter and an aquarium pump in one unit.

The pump performance of the aquarium pump is 300 l/h with a power consumption of just 2 W. The aquarium pump, which has an adjustable flow rate via a slider, features a swiveling outlet nozzle with a diffuser. Additionally, oxygen can be supplied to the aquarium through a hose.

The aquarium internal filter can be easily used for aquariums with a water volume of up to 40 l. Operating small aquariums becomes a simple task.

Upon delivery, the filter unit of the aquarium internal filter is standardly filled with activated carbon. A filter sponge serves as the second filtration stage. Of course, the filter unit of the aquarium internal filter can be filled individually, but it should be noted that the filter materials must be graded from coarse to fine.

Filter media:
1st stage: mechanical/part-biological filtration
2nd stage: chemical filtration (activated carbon, peat, phosphate remover, etc.)

When purchasing a new aquarium filter or after a complete cleaning, beneficial bacteria must be reintroduced. There are special bacterial cultures that can be added to the aquarium filter to facilitate the start.
