The inexpensive indoor device has proven itself in fresh water filtration. It is usually installed in aquariums with a volume of 150-200 liters. The plastic case is ergonomic, has no unnecessary parts, protruding elements, or play between structural elements. It is designed for long-term operation without switching off. To ensure high-quality operation, the device must maintain the 8.5 W power declared by the manufacturer. Its average productivity is 600 l/h, which makes it possible to purify water well and saturate it with oxygen.
The owners include the design of the outlet pipe as an advantage of this product. It is equipped with a special rotating nozzle that regulates the direction of flow. The aeration option makes it possible not to use additional aquarium accessories. Not all filters are easy to maintain. However, this model can be assembled and disassembled in a matter of minutes and is easy to maintain.
Description of equipment
If in the recent past most filters only performed mechanical purification of water from suspended matter and other contaminants, today equipment of this type allows solving problems with nitrates, nitrites and ammonia, providing optimal living conditions for even the most demanding tropical fish.
The design of the aquarium filter is simple and consists of the following components:
- water pump;
- housing with filter cassettes;
- compartment with sponges and filler for biofiltration;
- taps with tubes for water inlet and outlet.
The operating principle of such equipment is extremely simple. The water pump used creates a vacuum in the suction tube, which is immersed in water. Water is supplied from the nozzle into the filter housing, which passes through the sponges and compartments with biofiltration filler, after which it is directed under pressure into the aquarium through the appropriate hose.
Today, two main types of aquarium filters have gained popularity:
- internal;
- external.
Internal ones also include bottom filter units that can be placed under the ground, which allows you to solve problems with detritus and various contaminants that accumulate in sand and small pebbles at the bottom.
External filters include classic versions with baskets and so-called backpacks, which are intended primarily for small-power aquariums and are mounted on the back wall, providing high-quality mechanical purification of water and its aeration.
EHEIM Biopower 240 l
A productive and very efficient filter with a rotating pump and a modular design, EHEIM Biopower, designed for aquariums from 160 to 240 liters. It drives water through a complex of filter layers at a speed of up to 750 l/hour. The direction of the liquid inside is from bottom to top, the active component is SUBSTRATpro filler, which, in combination with an organic sponge, performs comprehensive cleaning from solid particles and excess bacteria, the filter also maintains nitrates at zero. It is possible to additionally install a carbon filter (optional). The output is water that is ideal for the quality of life of fish. A special feature of the system is a rotating pump that sets the direction for the movement of water, simulating natural flows, additionally enriched with oxygen. The device is attached to the wall using suction cups, and the kit includes replaceable SUBSTRATpro modules. You can buy EHEIM Biopower 240 l from 4,600 rubles.
ADVANTAGES Suitable for sea and fresh water; Solution for an aquarium densely populated with fish; Comprehensive cleaning from solid particles, bacteria and chemicals; Rotating pump to change the direction of water flow; Easy to attach to the inside wall of the aquarium.
DISADVANTAGES Frequent movements of the device weaken the suction cups.
Varieties and design features
The types of aquarium filters include the following:
- external;
- internal;
- bottom
As for design features, there are mechanical, chemical and biological options. They are all good in their own way, and have both pros and cons. Each of them is described in more detail below.
External
The external aqua filter is included in the category of pump devices. It is distinguished by the supply of water outside the aquarium from the main tank. The liquid passes through several filters at once (cascade). The materials used for these devices are peat, coal, padding polyester or foam rubber. The advantages of such devices are that the filler in them can not be changed for a long time, and the operation of the mechanism is almost silent. The external unit costs a little more than the internal one.
There are also disadvantages, which are that the filters can only be cleaned in liquid drained from the fish house. If it is still necessary to change the attachment, it will have to be done gradually. Such measures are due to the fact that one-time filtering immediately disrupts the biological balance of the ecosystem. A carbon filter element can be used as a filler. This variety is usually preferred by experienced aquarists.
Domestic
This submersible option is placed underwater in an aquarium. It is widespread among those who keep fish at home. The reasons for their popularity are the budgetary cost of ongoing maintenance and the mechanism itself. Such devices are divided into airlift (working like aeration) and pump-type. Despite the fact that they are quite popular, the built-in unit has some disadvantages. Among them:
- noise made during operation;
- the need for regular cleaning (about once a week);
- large amount of space occupied.
Such aqua filters are most often preferred by beginners in aquarium keeping.
Bottom
Such an aquarium filter can rarely be found in specialized stores. This device looks like a false bottom, under which there is a water purifying mechanism. This design creates the illusion that there is no filter in the aquarium. Soil with water passing through it can be used as a cleaning material. Nowadays, many fish breeders have abandoned bottom devices because they consider them not very effective.
BARBUS WP-300F
Expanded equipment for miniature containers Country: Russia Average price: 400 rub.
Owners of aquariums up to 20 liters should definitely pay attention to this model. Despite its mini parameters (with package dimensions of 13x8x6 cm, the filter weighs only 155 grams), the internal structure has received a lot of positive feedback. Firstly, its color completely harmonizes with the underwater flora and does not disturb the overall appearance of the interior. Secondly, the device is optimally functional, since at a power of 2 W it is capable of processing 150 liters of water per hour.
However, its main advantage is its excellent configuration. The set includes such attachments as “Water flute”, “Filtration and sprinkling”, “Filtration and aeration”, “Filtration and circulation”. Therefore, you can always choose the flow path option that is necessary in a particular case. The glass-type body, made of metal and plastic, is quickly attached to the wall of the container using suction cups. The large-pored sponge collects dirt and is easy to maintain. What users also highlight is the quiet operation of the device.
The need to use a filter in an aquarium
An aquarium requires special care and the use of certain equipment, in particular a filter. However, its installation is not necessary if there are few fish in the tank. Experts believe that 10 liters of liquid is enough for one underwater inhabitant up to 5 cm in size. Subject to these conditions, as well as timely removal of debris, changing water and connecting aeration, a good environment without a filter is created. Aeration saturates the space with oxygen and oxidizes harmful microelements. The dense population of the aquarium requires the installation of a filter.
The devices provide mechanical, biological and chemical filtration. The first cleans the walls of the tank using a sponge or a bundle of tangled fishing line, which captures dirt and debris. This treatment is suitable for goldfish and cichlids. The biological method is carried out using live bacteria and special fillers. This treatment removes toxic substances and waste products of fish and plants, and improves the environment. An effective chemical method is based on the absorbent effect of activated carbon. The carbon filler is able to absorb harmful impurities, remove ammonia and foul odor.
JUWEL BIOFLOW 6.0
Best filter chamber capacity (six elements) Country: Germany Average price: RUB 11,500.
Fine filter designed for containers holding 200-350 liters of water. The tank's own volume is 6 liters; according to this indicator, Juwel Bioflow 6.0 comes close to external-type devices. In addition, inside the capacious chamber there are 6 types of filter elements: special dense cotton wool and 5 sponges of varying degrees of density. They perform the function of complete mechanical and fine chemical and biological purification, due to which water retains its suitability for a long period of time. If the question arises about choosing an expensive but good model of internal filter, then experienced aquarists give preference to this particular candidate. Disadvantages include the high cost of the device and the rapid wear of coarse materials.

“My filter is a saboteur,” this is what one aquarist says about his filter, “It does its job silently.” This is of course a joke, since a silent filter for an aquarium is just a dream; everything that moves, and in filters this includes water and their mechanical parts, produces sound. Even a falling needle generates noise with a level of 2 dB.
Low filter noise is the same advantage of these devices as high performance. Few people will want to install a filter that perfectly purifies water, but rattles or hums like a powerful transformer.
Sources of noise during filter operation:
- beatings that generate vibrations of the moving parts of the filter equipment - the axis on which the impeller is mounted, low-quality bearings in the pump electric motor;
— air bubbles that hit the impeller and produce noise;
— difficulty in operating the pump, which occurs when the filter substrates of the filter are heavily contaminated;
- noise generated by air that is sucked into the filter (internal filters that provide simultaneous aeration).
Getting rid of the noise generated by air trapped in the filter (this often happens when using external filters) is quite simple - you need to rock it from side to side so that the air that accumulates under the filter head comes out. To reduce the noise level produced by the intake air, many manufacturers equip their filters with special mufflers that are placed on the suction pipe. If you are not satisfied with the noise level being reduced, you can reduce it even further. Russian aquarists have found such a solution - instead of the muffler proposed by the manufacturer, a silicone tube with a conventional ceramic sprayer is connected to the suction pipe, and a rotary tap is inserted between the pipe and the sprayer to regulate the air flow. As measurements have shown, after such an operation this type of noise is reduced to 6 dB, that is, to the noise level produced by the breathing of a out of breath person.
The noise produced by the impact of air bubbles on the impeller blades usually disappears as the filter accelerates. If this does not happen, pay attention to whether air from the aerator spray is getting into your filter and move it away from the filter suction holes.
As the filtering substrates become contaminated, the load on the electric motor increases, and when the calculated value is exceeded, it begins to hum - the solution is simple, it’s just time to clean the filter.
In the struggle for buyers, campaigns that produce aquarium filters and strive to create the quietest filter for an aquarium are paying increasing attention not only to the high performance of what the filter is intended for, the quality and complexity of filtration, but also to the comfort of their operation, which includes the absence of noise at work.
To overcome the noise of its filters, which aquarists have complained about in the recent past, the Polish company AQUAEL has focused its efforts on reducing the possibility of transmitting vibrations from the mechanical part of the filter to the glass of the aquarium, which acts as a resonator. New models, produced under the FAN article number, are equipped with special vibration-damping suction cups or additionally purchased magnetic holders. The installation of systems that make it possible to smoothly adjust the pump’s performance has also led to a reduction in noise, which allows it to be used exactly to the extent necessary to ensure the flow of the required force.
Filters of models of the AQUAEL UNIFILTER line, depending on the brand, are intended for use in aquariums, depending on the brand of the product, from 30 liters to 350. These filters produce significantly less noise than models of the FAN line. This was achieved by changing the location of the impeller axis - not vertically, but in a horizontal position. The use of ceramics for the manufacture of the axle itself and the high precision of the manufacturing standards of the block in which it is strengthened have almost completely eliminated the possibility of axle beating - the noise has sharply decreased while power has increased.
AQUAEL also offers modified Circulators under the Turbo model line brand, which have a capacity of 500, 1000, 1500, 2000 liters per hour. To reduce noise levels, the designers used a ceramic rotor, which at the same time made it possible to use these filters in marine aquariums.
In the Tetra internal filters of the IN model line, designed for filtering water in aquariums from 10 to 200 liters, the manufacturer, to reduce the noise of the products, used a thickened ceramic impeller axis and thickened bearings in the vibration-damping rubber base.
Tetra internal filters from the EasyCrystal Tetratec line are even less noisy, designed for mechanical and biological filtration in aquariums from 15 to 150 liters. The numbers in the model brand indicate the performance of the filters. It was possible to increase the power of the filters while reducing noise thanks to the use of a unique magnetic turbine.
The internal filters of the three-stage cleaning Hagen Fluval model U series are quite quiet in operation, which was achieved thanks to the new design of the rotor and the entire rotor compartment. The external filters of the G3 line use innovative design solutions for installing the impeller, the filters are equipped with automatic air removal systems - all this has dramatically reduced noise compared to previous models.
The JBL CristalProfi greenline filters turned out to be very quiet. The designers achieved a reduction in noise levels using special bearings and high-power electric motors - since the engine does not operate at full power, it does not produce noise.
You can buy a quiet filter for an aquarium by choosing a filter model from the Italian company Sicce that suits your needs. The manufacturer achieved it. low noise level of their filters thanks to the use of a special design development - a floating rotor system, which at the same time increased the durability of the filters. The external filters of this company in the SPACEEKO+ model line are equipped with a self-lubrication and self-cleaning system for the pump impeller, which significantly reduces noise and increases the uninterrupted service life of the filters.
During testing, filters from the Japanese company ADA, which are made by hand and use not only modern noise-reducing technologies, but also a vibration-damping and noise-insulating aluminum housing, showed unusually quiet operation. The only drawback of these filters is the need to use a voltage converter from 220 volts to 110.
Among all the external filters tested, the quietest were the Eheim filters, and especially the Eheim Xperience, which achieved an even greater reduction in noise levels thanks to the use of unique reversible rotors.
External filters from all manufacturers, which are sold at aquamegamall.ru, placed in an aquarium cabinet, the internal surfaces of which are finished with soundproofing material Mappesil (foamed polyurethane), showed a noise level of 3 dB, which corresponds to the noise produced by a falling needle. And this is another argument in favor of ordering an aquarium and equipment for it from AquaMegaService.
