The interval between filter cleaning depends heavily on the type of filter, the filter volume and also the number of fish kept in the aquarium.
It is certainly important that filter cleaning and water changes are not carried out at the same time, otherwise the balance in the aquarium will be disturbed too much.
Replace the filter floss. The other filter media do not have to be replaced every time, but can also be washed out (read on the filter medium how long the respective medium can be used).
Wash the filter medium in a kettle of aquarium water and not under the tap. This preserves some of the bacteria.
Never wash all the filter media at once - it is advisable to draw up a cleaning schedule.
When cleaning, also remove the rotor and clean the motor.
Nobody usually likes visible technology in the aquarium, but without technology it is (almost) impossible.
The technology can be covered with roots or stone structures. However, make sure that the flow through the filter is not blocked.
In a well-planted aquarium, the green filters or pipes disappear.
If you have a black filter, you can also attach a black film to the back (outside) of the aquarium so that the filter is no longer noticeable.
The internal aquarium filter is compact and is placed inside the aquarium. It draws in water through a pump mechanism and passes it through various filter media to remove dirt, excess food and harmful water components. Internal filters are easy to install and ideal for smaller aquariums or those with little space around the tank.
An external aquarium filter, on the other hand, is positioned outside the aquarium and works by using hoses to transport the water from the tank into the filter and back. These filters often offer greater filter capacity and more efficient cleaning, as they can accommodate a wider range of filter media. External filters are particularly suitable for larger aquariums and offer the advantage that they do not take up any space in the aquarium and do not impair the view in the aquarium.
Both filter types have their advantages and disadvantages, and the choice between internal and external filters depends on various factors, such as the size of the aquarium, the specific needs of the fish and the space available.

Mein Hamster Theodorius hatte vom Futter hier drei Monate aggressiven Durchfall. Muss an der herausfordernden Qualität liegen, der arme ist sich sonst nur chicken-nuggets gewohnt…
