Internal filter guide

A filtering of the water in one fish tankis usually mandatory to build or maintain a stable biological system. An aquarium filter cleans the water mechanically and on a biological basis. It removes dirt from the water and provides a good base for accumulating useful bacteria that help break down or convert the dirt. Basically, two types of filters are offered: outdoor and outdoor internal filter , Decisive criterion in the selection of the type is the size of the aquarium. From about 100 liters are mostly external filtersappropriate. In smaller aquariums are usually internal filter used – and exactly this is it here. They are typical beginner equipment, namely simple and inexpensive. However, soil filters are usually not included among the internal filters, although they are also installed inside the aquarium. There is no justification for it, it has just naturalized.

The filter principle and the structure of an internal filter

In the filter derives a rotary pumpthe water through one spongewhich can be made of different material. It mechanically filters out the particles of dirt and, through the bacteria in it, biological purification is also carried out by biochemical conversion. internal filter have a relatively small size, suck the water mostly from below and are often with suction cups on the aquarium inner glass or with hanging devices on the fish tank back wallattached. The individual elements are:
– Filter container with open-pored sponge
– Filter head, in which usually the centrifugal pump and its drive motor is integrated
– The engine is usually operated electrically, but there are also air-aisle variants
– Cable with plug to supply the motor with operating voltage
– Impeller pushing the water out of the top of the filter
– Some filters are equipped with a special nozzle (diffuser), which sucks additional air and introduces into the aquarium, which is advantageous at high stocking

Advantages and disadvantages of internal filter

Advantages:
– small size
– easy installation, care and cleaning
– Highly recommended for beginners, already often included in aquarium sets
– possibly equipped with diffuser for advantageous water / air circulation at high stocking
– Price is usually much lower than external filters
– no risk of leakage through the filter

Disadvantage:
– Filter performance is lower than with external filter, therefore not suitable for larger aquariums
– The positioning of an internal filter often looks aesthetically unsuccessful, d. H. the optics disturbs and should be hidden, z. B. by installing behind plants
– Filter system is not expandable

Tips for use and precautions

– When cleaning the filter, do not wash the sponge hot or cold. That harms the bacteria. It is best to express the filter in the aquarium water, z. B. in drained water after a partial water change.
– Consider the existing or planned biosphere in the specific filter design, d. H. in small fish or shrimp, a normal filter that sucks the water through slits can cause great damage. Remedy can be created by coating the intake with z. B. fine-meshed but water-permeable fabric. While it may be possible larger particles of pollution get stuck, but the animals are spared.
– Some aquarists have an aversion to electrics in the water. The engines in internal filters, however, are usually sealed waterproof and safety concerns are usually unfounded, unless there is a defect. However, if work should be done in the aquarium where the hands are submerged in or in contact with the water, then in any case all plugs must first be pulled to safely disconnect the power supply, as water and electrical voltage are a dangerous combination.
– The filter should be inspected regularly and the sponge should be cleaned. However, the respective conditions must be taken into consideration, ie. H. too frequent and frequent cleaning may cause more harm than good, as the bacterial fauna in the internal filter It can be disproportionately attacked.
