The SunSun HJ-611B aquarium internal filter combines an aquarium filter and an aquarium pump in one unit.

The pump performance of the aquarium pump is 450 l/h with a power consumption of just 6 W. The aquarium pump, which has a flow rate that can be regulated 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 60 l, making it a breeze to operate small aquariums.

Upon delivery, the filter unit of the aquarium internal filter is pre-filled with activated carbon as standard. A filter sponge serves as the second filter stage. Of course, the filter unit 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/partially 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 need to be reintroduced. There are special bacterial cultures that can be added to the aquarium filter to facilitate the startup process.
