The best filter for aquarium: types of filtering, photo-video review
– These are the simplest and at the same time effective filters for an aquarium. Some “old-fashioned” call them “glasses.” The essence of their work is very simple – the filter has a pump (motor) and an absorbent sponge.
The pump pumps the aquarium water, which passes through the sponge, is cleaned. Such filtration effectively copes with the removal of large contaminants: food residues, fish excreta, residues of dead organisms, etc.
If you have a small aquarium and not very large fish swim in it, such a mechanical filter will be quite enough.
– These are filters that provide filtering through various absorbents. The most common absorbent is aquarium coal. Also in the aquarium used and other absorbents – ion exchange resins, for example, zeolite.
Filters that provide for the possibility of such filtering are more practical than mechanical ones. Since the pores of absorbent materials are able to absorb smaller particles of pollution of aquarium water, and ion exchange resins can effectively fight even the most harmful poisons – ammonia, nitrite and nitrate, which are formed and gradually accumulate in the aquarium.
Biofilters filters and aquarium biological filtration
– These are filters that combine the possibility of using various types of filtration of aquarium water. Some filters have all three of the above filtering types.
But it is worth noting that even the simplest mechanical filter can be used as a combined one. That is, use in it and absorbent sponge, and for example aquarium coal.
The aquarium filter is a device that cleans a decorative aquarium in which fish, plants and other animals live. Filters for an aquarium do not only clean the water, but also the soil, so these devices can be of various kinds. Which is better to install a filter for an aquarium?
In this matter it is necessary to understand in detail, given the functionality and purpose of the equipment.
Filtering devices are characterized by the features of the design position and a set of functions. Therefore, they are of the following types:
Internal filters for the aquarium – they need to be installed inside the tank. These are the most famous devices for cleaning home pond. It is better to buy those who start the aquarium business, because they are inexpensive and easy to operate.
Their main drawback is the bulkiness, which occupies a considerable area inside the aquascape.
Watch the video story about the internal filter.
External filters for the aquarium – they are preferred by experienced aquarists. This type of device is installed on the outside near the tank, and 2 tubes are placed in the water.
The first one pumps out stale water, the second one pumps clean after the cleaning process. The advantage of an external device is a high level of efficiency, ergonomics.
Such equipment is more expensive and takes up a large space behind the aquarium.
Mounted filters for aquarium – this type of device is installed near the wall of the tank, and the mechanism with the filter is lowered into the water. While he gained wide popularity among fans.
Bottom filters for the aquarium (false) – the filter plate of the device is laid out on the bottom of the tank, and on top is lined with a soil substrate. Cleans the soil and water from harmful impurities that remain after uneaten feed.
The filtration process starts from the bottom, and goes up, as a result, the water is purified twice – through the filter and through the soil. The disadvantage of such installations is a low degree of performance, a complex operation scheme.
They are not installed in spacious tanks.
Types of elements for filtering aquarium environment
The process of filtration inside the aquarium is of these types:
- Mechanical (grains of small debris are separated);
- Biochemical (harmful substances and impurities are neutralized).
These functions are performed by filtering elements that are present in the device. They remove a certain amount of accumulated dirt, freeing water space from harmful substances.
Sponge filter – inside the mechanism there is a sponge filter element, of a large-porous or fine-pore structure. Dirty water is absorbed by pressure, it passes through the pores of the spongy material, and leaves mechanical debris on it (uneaten food, plants, extraneous fragments). After a week of continuous work, colonies of beneficial bacteria will appear on the sponge, which will function as a biological “filter”, freeing water from accumulated nitrates and methane.
Spongy tissue needs cleaning every 14 days. The permissible terms of cleaning the sponge are given in the instruction manual of the device.
Activated carbon is a filler for an aquarium filter that purifies water qualitatively thanks to its pronounced chemical properties. However, when using activated carbon, you need to be careful: the full saturation of the sorbent with harmful impurities, can give a backlash.
Harmful substances with excessive accumulation in the coal, will be thrown back into the water, which is fraught with negative consequences for all inhabitants of the aquarium. Better use other types of cleaners.
Biological fillers from multi-pore ceramics are popular in modern aquariums. These are ceramic balls, the surface layer of which quickly accumulates in beneficial microorganisms that create millions of colonies.
Biological treatment in this case increases several times. Ceramic cleaning devices are used simultaneously with mechanical filters.

Which filter is better to choose for a home aquarium? All filtering installations to some extent well cope with their functions. All manufacturers of cleaners provide a wide range of devices that have their own advantages and disadvantages.
Before buying an appliance, consult with experienced aquarists and vendors.
- For a spacious tank you can buy an internal filter. There is a good brand of aquarium filters called “Aquael Fan”, which produces cleaning mechanisms in Poland. Devices of this brand are easily operated, reliable in use, and do an excellent job of cleaning the water environment. They also saturate the water with oxygen (produce aeration).
- Equipment of the German company “Eheim” is in great demand among aquarists. The cleaning devices of this manufacturer are noiseless; they can be used in tanks of any capacity. They perfectly save the internal space in the aquarium. You can purchase an external filter, but it can be expensive.
- One more good cleaning installations of the Polish manufacturer Aquael UNIMAX. They are inexpensive, high quality and effective.
- The well-known German company Tetra, in addition to fish feed, also produces biological water purifiers. They perfectly remove pollution, are able to work without replacing the filter elements for at least six months.
- Bottom filters for aquariums also come from different manufacturers. Their prices are relatively low, but their maintenance takes longer. Famous manufacturers of bottom filters: Aquarel, Eheim, Resun.
At first glance it may seem that the main differences between the filters are only in their appearance. But, in fact, the difference is not only in size, color and material. The most simple and economical devices have the appearance of foam sponge; Such a filter can be either open or hidden in a plastic container equipped with a tube.
The latter connects the cleaning device to the compressor. Thus, the air passes through the compressor itself, followed by water with particles of bacteria and dirt.
The liquid is filtered and fed back to the aquarium cleaned.
Buying this filter, do not forget to pay attention to adjusting the power of the air flow. Otherwise, the inhabitants of the aquarium will be sucked with water into the compressor. It is unlikely that the sponge filter will be the answer to the question “which filter is better for an aquarium.”
The thing is that after a couple of weeks the device becomes clogged and stops working fully. Therefore, every 2-3 weeks this filter should be removed and cleaned independently.
This is precisely the disadvantage of the sponge cleaning device, since removing it, you raise the water sludge and send it back to the bottom of the aquarium. In addition, the microbiological climate of the “water kingdom” is disturbed.
Also, you will not be pleased with the noise filter and its low performance.
The advanced, best filter for an aquarium is a glass filter. It is also based on a sponge or foam rubber, but its “insides” are enclosed in a body having an elongated shape.
In addition, this device has an electric motor. Today this species is especially popular.
In case of a choice between several manufacturers, do not give preference to Chinese products. Its quality can hardly be called excellent.
Certainly, filters made in Italy or Germany will differ in special reliability. They are slightly inferior to devices from Poland (their products quickly clogged up).
The cost of the filter depends on its power. In order to find the best option, calculate the required power. Determine how much liquid the tank holds; for each liter, on average, it accounts for about 3 liters of the cleaning device’s hours of operation.
A great option – filter with adjustable power.
Arrangement of an aquarium requires consideration of many factors, because it is far from a self-sufficient system, it constantly requires the introduction of the necessary substances and purification from products of pollution and decay. An important device that provides both of these functions is the filter.
Therefore, you should find out which filter is better for the aquarium.
Immediately it is worth making a reservation that deciding which filter for the aquarium is better to choose, it is necessary to take into account the volume of water for which it is designed. After all, not even the best instance of the filter can cope with the purification of the volume of water two or three times its calculated indicator.
For small aquariums fit internal filters, reinforced on the bottom or walls. Purification here occurs by sucking water through synthetic cotton wool or foam rubber.
Bottom internal filters hidden under a layer of soil look more beautiful, but this design makes it difficult to rinse the filter material, which is simply necessary from time to time, therefore, wall-mounted internal filters for an aquarium are considered more convenient.
External aquarium filters are considered to be much more convenient and efficient. They are located above or behind the aquarium.
As the filtering material in them various porous materials can be used. The most effective and convenient are filters located above the surface of the aquarium. Water is sucked into them and, passing through the filtering material, drips back into the aquarium.
When the filter is clogged, the tank glass overflows, and the water flows into the aquarium again. This is a clear signal that indicates the need to wash the filter, which is carried out indiscriminately with the basic structure of the water purifier.
Typically, the filter material is easily removed and washed, and if necessary, replaced with a new one.
