Aquarium external filters as aquarium filters for aquariums
External aquarium filters are indispensable components for the efficient cleaning of aquarium water and make a significant contribution to the health and well-being of the aquarium inhabitants.
An aquarium external filter, also known as an external filter for aquariums, is a device used to clean and clarify the water in an aquarium. In contrast to internal filters, which are located in the aquarium itself, an external filter is placed outside the aquarium, i.e. externally as an external filter.
How the aquarium external filter works
The operation of the aquarium external filter comprises several interlinked steps:
- Suction
At the beginning of this process, there is a suction device at the inlet of the aquarium filter. This device is connected to the aquarium by means of a tube or hose and draws water from the tank into the aquarium filter. This water flow is generated by an electric pump. - Mechanical filtration
As soon as the aquarium water enters the aquarium filter, it normally undergoes mechanical filtration. In this phase, coarse impurities such as food residues, plant waste and coarse particles are effectively removed. This cleaning is often carried out using special filter media such as foam or filter fleece. - Biological filtration
The next step is biological filtration. At this point, special filter materials provide a surface on which beneficial bacterial colonies can thrive. The bacteria play a key role in converting harmful metabolic products, such as ammonia and nitrite, into less harmful compounds, especially nitrate. This process is of great importance for maintaining healthy water quality and the well-being of the aquarium inhabitants. - Chemical filtration
Some external aquarium filters also have separate chambers or media for chemical filtration. Here, activated carbon or other chemical substances can be used to remove impurities and unwanted odours from the water. This additional level of purification helps to keep the aquarium water crystal clear. - Recirculation
Finally, the purified water is returned to the aquarium via the outlet of the aquarium filter. This outlet is usually positioned in such a way that it ensures an even flow and a sufficient supply of oxygen throughout the aquarium.
Advantages of external aquarium filters
Aquarium external filters offer a number of advantages for maintaining an aquarium. These aquarium filters are extremely efficient in filtration as they offer mechanical, biological and optional chemical cleaning. Their larger filter tanks and media chambers allow for better biological filtration and provide more space for beneficial bacteria. By moving the water surface, they also improve the oxygen supply in the aquarium. In addition, they are usually quieter than internal filters and easier to maintain as they are placed outside the aquarium. The use of an external filter helps to improve the water quality, which in turn has a positive effect on the health of the aquarium inhabitants. These aquarium filters are also more aesthetically pleasing as they keep the inside of the aquarium free of obstructive filters and hoses. Finally, they are scalable to meet the requirements of your aquarium.
Aquarium external filter types
There are different types of external aquarium filters for aquariums, each of which has its own advantages and disadvantages. These aquarium filters are crucial for the water quality and the well-being of the aquarium inhabitants. When choosing an aquarium filter, you need to consider factors such as the size and type of your aquarium, the specific requirements of your aquarium inhabitants and plants, and your budget. Some aquarium filters are more versatile and can be customised for a wide range of aquariums, while others have specific water movement requirements.
Choosing a suitable outdoor aquarium filter
Choosing a suitable outdoor aquarium filter requires careful consideration. Firstly, you need to determine the size of your aquarium to ensure that the aquarium filter is adequately sized. Think about the needs of your aquarium inhabitants and aquarium plants in terms of water quality and water movement. Decide whether you need mechanical, biological or optional chemical filtration, with biological filtration often being the most important. Consider the noise level of the aquarium filter and your budget. Ultimately, choosing an aquarium filter is crucial to ensure the water quality and health of your aquarium inhabitants. Also follow the manufacturer's instructions for installation and maintenance carefully.
Aquarium external filter care & maintenance
The care and maintenance of aquarium external filters is crucial to ensure the water quality in the aquarium. This includes regular cleaning of the filter media, removal of deposits in the filter housing and checking the pump performance. Keeping the inlet and outlet pipes clean is also important to maintain water circulation. Partial water changes are essential to reduce waste products. Checking seals and hoses as well as regular water quality tests are also necessary. The exact frequency of maintenance depends on various factors, such as the size of the aquarium and the requirements of the aquarium inhabitants. The maintenance of the external filter also contributes significantly to the health of the aquarium and should therefore not be neglected.
Tips: Avoid using hot water to clean the filter material in order to preserve the beneficial bacteria required for biological filtration.
When changing filter media, do not replace all filter media at the same time to minimise disruption to the biological balance in the aquarium.
If your external filter has seals, it is advisable to use silicone grease specially developed for aquariums to maintain the seals. This not only extends the life of the seals, but also maintains the functionality of the external filter.
To summarise, external aquarium filters are indispensable for the efficient purification of aquarium water and make a significant contribution to the health and well-being of the aquarium inhabitants. They provide mechanical, biological and, if necessary, chemical filtration to remove pollutants and maintain the biological balance. The right filter should be selected carefully, taking into account the size of the aquarium, the aquarium inhabitants and aquarium plants, the budget and other individual requirements. The care and maintenance of the aquarium filter are equally important to maintain its performance and water quality.
