How To Put The Filter In The Aquarium

It so happened that because of its availability, compactness and ease of use, as well as installation in the aquarium for beginners, it is the pump filters that become the first filters. Models produced in the present moment of time, a huge amount. But in detail on the choice of a specific model, we will not dwell today. We will talk about how to properly install an already selected and purchased filter in the aquarium.

Any internal filter pump consists of two parts: the engine pump and the filter part. The motor pump is the pump that drives and creates a flow of water through the filter element. And the filtering part is a compartment with a filtering element located in it. It is he who is responsible for the purification of water from turbidity and suspended particles. By execution, all internal filters are made in a sealed design, so the only way to use them is to completely immerse them in water.

Mounting methods

The main methods of mounting filters on glass manufacturers call:

How To Put The Filter In The Aquarium

With the help of suction cups.

With the help of an additional bracket.

Combined (suction cups + extra bracket).


Mount with suction cups is the simplest and most effective. This option allows you to easily remove the filter from the water. Suckers are located on the body of the device and removed from the aquarium with it, or performed on a separate site. In this case, the filter is attached to the bracket using grooves or latches and, if necessary, removed from the water separately.

It is also worth noting that over time, the suction cups lose their elasticity, and the fastening reliability decreases. In this case, they are replaced by new ones. In addition, the filter mounted on the suction pads not on clean glass, but on the bacterial film, is prone to slipping from its original location. Therefore, the installation site of the filter should be thoroughly cleaned from slippery coating.

Optional bracket

Fastening with the help of an additional bracket is more reliable, since it allows you to hook onto the edge of the aquarium with a special plastic hook. A filter installed in this way is not subject to slipping. However, manufacturers often complete their products with a bracket that is designed for installation on thick glass (used either in large aquariums or made of plexiglass). As a result, it is not possible to perform a reliable fixation of the device in the aquarium, which is the source of extraneous sounds. Also, the presence of a hook extended outside the vessel can make it impossible to install the aquarium cover or to pass it into one of the specially made windows. These slots are not always well located in terms of the position of the filter, and can also unsuccessfully affect the design of your aquarium so that they will dictate the place of installation of the filter in the tank.

Maintenance of the filters mounted on the bracket is the most convenient, since removing the product from the aquarium does not require lowering your hands into the water.

Combined method

A combination of mounting method is called the option to install the filter at the same time using suction cups and a bracket. This type of installation is distinguished by the most reliable fixation of the product in the aquarium, although it collects the disadvantages of both types of fasteners.

Conditions of effective work

For effective operation of the internal filter requires a number of conditions:

The filter should create a sufficient flow of water through the filter element, that is, have adequate performance for the aquarium of your chosen size.

Placing the filter in the aquarium should exclude the presence of stagnant zones.

The filter must be accessible for maintenance and cleaning.

Installing the device in the aquarium should lead to the realization of the objectives pursued.


The filter capacity is determined by the amount of water in liters that has passed through the filter element per unit of time. It is the main one of the units determining the filtration rate, and should be selected from the condition that 4-5 volumes of your aquarium should be pumped through the filter per hour.

No stagnant zones

Placing the filter in the aquarium should exclude the presence of stagnant zones. This means that the filter should create a flow of water in the aquarium of such strength and direction that the entire volume left areas or zones where the flow of water is very low or completely absent. This is a guarantee that the entire volume of the aquarium will be serviced by the filter. It is unacceptable that only part of the internal space was filtered due to blockage of the flow by decorations, flow direction across the aquarium, etc. In the case of using large volumes or containers made very long, it would be reasonable to use several filters installed on opposite sides. Many modern models of filters are equipped with a number of devices that help to implement this rule. For your convenience and adjusting devices for specific conditions, manufacturers equip filters with flow controllers, swivel heads and diffusers to move water in the direction you need.

Availability for maintenance and cleaning

Proper selection of a place to install a filter in an aquarium should provide easy access to it for maintenance and cleaning. It is no secret that over time the filter element, and the pump itself, is clogged with particles of dirt, fish waste, etc. This is logical, because for this we set the filter in the aquarium. Therefore, even the most high-tech and modern device after some time will require maintenance and cleaning. For internal filter pumps, this means removing them from the aquarium. Therefore, at the planning stage of the design and selection of the installation location of the product, it is necessary to attend to the convenience of this process. Since the dismantling of parts of your design, moving the slugs and damaging the plants for weekly cleaning of the filter element will bring only negative emotions.

Realization of goals

Installing the device in the aquarium should lead to the realization of the objectives pursued. This imposes certain requirements on the functionality of the filter used. If you intend to operate the filter in aeration mode and do not install the compressor additionally, then at least a special nozzle should be included in the instrument configuration. As a rule, the additional purchase of non-compliant devices may bring additional difficulties in finding original accessories or selecting compatible ones.

Modes of operation

For the most part, all filter pumps, in addition to their main purpose (water filtration), can also perform additional functions. This is aeration, circulation, sprinkling.

Consider these options:


The main version of the filter pump. Its implementation does not require any devices, since this is the main thing for which we use a filter. Without water circulation, there will be no its current, which means that filtration will not be carried out either. A non-circulating filter does not perform its primary function. Sometimes the product is supplied with an expanding nozzle, which forms a wide flow of water, which reduces the eddy flow in the aquarium while maintaining the original performance. In addition, this use case is also the most preferable in terms of noise. However, when using the filter in the circulation mode, it is worthwhile to attend to the organization of aeration (at least at night) with the help of a compressor or an additional aerator pump.


The most commonly used filter pump function. To this end, the manufacturer supplies its products with an additional nozzle, which is a special diffuser with an attached air intake hose. Often at the end of the hose is set to control the intensity of the blow. Such use of the device allows to reduce the amount of equipment used to maintain the aquarium. However, it is worth remembering that the intensity of aeration will strongly depend on the performance of the filter and its depth of installation.

With the selected and constant filter performance with increasing depth of its installation, the intensity of aeration decreases, and when a certain depth is reached, it stops altogether.

Also, the main differences between the aeration performed by the filter and the aeration performed by the compressor are the impossibility of the pump to blow the bottom layer of water with air. In addition, there is a potential danger of misleading fish at night if the filter is stopped due to heavy pollution (if you, for example, went on vacation). In addition, among the shortcomings can be noted the decrease in performance and filtration efficiency with respect to the circulation mode, as well as an increased noise level.


This mode is performed using a special nozzle, called "flute", and additional adapters and fixtures. Sprinkling allows for very intense vertical mixing of water layers without creating strong streams. Such a solution is most justified for the use of high-performance filters in herbal herbal aquariums, where the intensive current has a detrimental effect on plants. In this case, the flute is located along the long edge of the aquarium and water is ejected through small holes made along its entire length. The closer the length of the flute to the length of the aquarium, the more intense the circulation of water and the weaker the flows created in it.

Smaller flutes are installed directly on the filter housing and do not require additional fastening, while long ones are installed using suction cups on the wall of the aquarium and connected to the pump with a plastic tube or flexible hose.

The classic arrangement of the flute involves the installation above the water level. Such an arrangement ensures the saturation of water with oxygen, due to the intensive mixing of its upper layers, and also helps to get rid of the bacterial film. Of the minuses worth noting that this solution is the most noisy of all the options for using the internal filter pump. The noise level is 8 dB higher than when the product is operating in circulator mode and 2 dB in aerator mode. In addition, there is a noticeable decrease in pump performance due to the need to pump water through narrow holes in the flute.

If you still appreciate all the advantages of this installation option and decided to use it, then as a measure to reduce the noise level, we can recommend the direction of the water streams leaving the flute on the glass of the aquarium. The application of this method, however, will reduce the efficiency of aeration.

Sprinkler mode with the direction of flow of water from the flute to the glass

It is believed that in herbal aquariums, the flute must be located below the water level to avoid mixing its upper layers, which leads to loss of dissolved carbon dioxide. With this option, the installation does not saturate the water with oxygen, does not break the bacterial film, however, the noise level is comparable with the noise of the pump operating in the circulation mode. However, in this case, to perform aeration at night, you need to raise the flute above the water level (if the noise from the aquarium does not interfere with your sleep or it is installed in non-residential premises) or organize air blowing through other methods.

How to install the internal filter in the aquarium? Such a question often baffles novice aquarists. It seems that everything is clear, but how to do it correctly, so that God forbid something did not happen – it is not clear. Fully immerse the filter itself in the water or not? And why, I wonder, such a transparent tube?

The instruction to the filters is not always detailed and clear, and in the photo on the box it is not clear whether the filter is immersed in water or not.

The internal filter on the so-called that it is inside the aquarium. The external filter is more bulky and designed so that it is placed outside the aquarium.

The internal filter is immersed under water completely so that 2-4 cm of water remains above it. It is attached to the wall of the aquarium with the help of suction cups included in the filter package. A small flexible hose attached to the kit is needed to supply air, so one end of it is attached to the corresponding hole on the filter nose, and the other is taken out, you can fix it on the upper edge of the aquarium wall (often for this purpose there is a mount). In any case, the air should be taken above the water level in the aquarium.

Most often, on the spout of the internal filter (some at the end of the air hose) there is an air supply regulator, it can first be placed in the middle position. In the future, adjust as you need. Some aquarium fish love the strong current created by the filter, and some just can not stand it.

Only after installing the filter and attaching all its details, can it be included in the network. In the future, all manipulations in the aquarium water should be carried out with the filter turned off, since no device is immune from malfunctions, and they, in turn, can lead to electric shock.
Sometimes newcomers ask: – Why are there no bubbles from the filter? – In principle, when adjusting for a weak flow of water, bubbles may not be. If you see a wave of water in the aquarium, the filter is working properly and that is enough. Water is saturated with oxygen from the surface due to the waves, as in nature, because there are no devices there.

For which aquariums do you need an internal filter?

The installation of the internal filter is appropriate in aquariums of small and medium displacement of up to 200 liters, in which the cleaning function is usually tried to be combined with additional aeration of water.

These devices are quite compact and work relatively quietly, so beginners tend to buy them for small bodies of water – many are frightened by the difficulty of installing external models or the risk that the outside filter will be dropped by an animal or child. In addition, submersible equipment is chosen by the owners of aquariums, which often suffer from power outages – such equipment will not leak and will not flood the floor. And it’s easier to clean the internal filter. But if the aquarium is very tiny, and the submersible model takes the usable space of the reservoir – what to do then? A partial solution may be a corner filter.

How to install an internal filter

Installing an internal filter in an aquarium is simple. This device does not require the purchase of additional equipment or upgrades, therefore, regardless of the model, it is assembled in full accordance with the user’s manual.

1. Familiarization with the device.
Correct Installation of any filter begins with checking its completeness and reading the instructions. We recommend to do this before buying a cleaner. If you doubt your design abilities, it is better to ask the consultant to demonstrate to you the assembly process or describe it thoroughly.

2. Assembling the filter.
Almost all internal filters are collected by one algorithm. The first step is to place the filter material in the “glass” of the device. Then, if designed, insert the rotor into the pump. Attach the pump to the glass and connect the aeration tube. If the recognition of the details makes you difficult, check out the video attached to the article.

In some models, the mounting plate is separated from the case. Insert the fasteners on the “glass” into the grooves provided for it and place the suction cups in the appropriate connectors. Everything is ready to install the filter in the aquarium!

3. Fastening apparatus.
Almost all Fish Tank Filters are fixed on the tank wall with suction cups. Simply press them against the glass and press them firmly. Submersible filters should be under the mirror of the water entirely – in any case, do not turn on the device if it protrudes from the water. The correct depth of placement of the filter – 2-5 cm from the surface. One end of the aeration tube must always be in the air (see a photo).

4. The first inclusion. Inclusion after installing the filter in the aquarium essentially involves working in test mode. For this reason, it is recommended to observe the operation of the filter. Adjust the depth of the dive.

5. Power setting.
At the time of first switching on or immediately after it, it is recommended to turn the power regulator to average values. Further adjustment should be carried out taking into account the volume of the aquarium, the degree of its pollution and, of course, the habits of its inhabitants. Some fish, in particular, with small and weak fins, do not tolerate too strong a current.

What aquariums need an external filter

The external filter contains a larger amount of filtration material, therefore, as a rule, it provides not only mechanical and chemical, but also biological water purification. A large area of ​​the filtering membrane serves as a housing for more nitrifying bacteria and nitrobacteria, the colonies of which decompose dissolved organics to less toxic compounds. For this reason, and in view of the high performance of the devices, the installation of an external filter is provided for aquariums over 200 liters. Some aquarists equip smaller bodies of water with them – but not less than 100 liters.

At the same time, the only drawback of canister devices is the risk of water leaking from the external tank. This may occur if the pads are worn. Some manufacturers took care of this problem and developed a leakage protection system.

How to install an external filter

Despite the comparatively expensive, external filters are easy to install and install. The myth of the difficulties of installing an external filter in an aquarium should not push to the choice of familiar, but less efficient, immersion models.

1. Choosing a place for the canister.
The design of the filter involves two ways of placing the canister: above or below the water level. The first option allows you to hide the body of the device in the tank cabinet and not to force the apartment bulky technique. The second (as in a photo) – save electricity and reduce noise. It is believed that for the filter to work effectively it is necessary that its upper point is not higher than 20 cm from the water level.

2. Assembling the filter.
Assembly of the filter is carried out according to the instructions. The process is quite easy. It is necessary to put a filter sponge or other cartridge, as well as a layer of biomaterial into the flask of the device, in the lower half of the canister. Assembly of the mechanical part of the filter is usually not required – the manufacturer packs it in ready-made condition. Then the suction and exhaust hoses are inserted into the apparatus.

3. Placement of hoses.
Hoses for collecting dirty and filing filtered water are placed in opposite corners of the aquarium – this increases the efficiency of work and creates the necessary circular circulation. As soon as all elements are inserted into the device, it is necessary to open the retractable hose and wait until the filter is full. After that, the first hose is closed and the second one is inserted into the hole. When air comes out of the tubes, you can test the equipment.

How to install a filter in the aquarium?

The organization of a home aquarium is always associated with the need to install an internal filter. It is simply necessary for the normal existence of fish, as it saturates water with oxygen, improves the circulation of water, and mechanically purifies water. But for beginner aquarists, this often becomes a problem, and they wonder how to install an aquarium internal filter.

How to install Fish Tank Filter?

The internal filter is called internal because it is completely immersed in water. The water level above it, depending on the depth of the aquarium, should be from five to eight centimeters.

The filter is attached to the wall of the aquarium with the help of special suction cups, which in most cases are included in the kit.

A flexible transparent tube, which is called an air vent hose and is designed to supply air, at one end is attached to the spout of the filter, and the other is led outside the aquarium. The tip of the air vent hose, located outside the aquarium, should be located higher than that attached to the filter nozzle.

In addition, when installing the filter should pay attention to the fact that the power of the air supply can be changed using a special regulator, which is either at the tip of the air vent hose, or on the spout of the filter. At first, put it in the middle position. And you can adjust the position you need, looking at the fish. There are types of fish that love a strong current, and there are also those that do not tolerate it. With a weak power level, the bubble filter may not be, in this case, a slight wave of water will tell about its proper operation.

After the installation of the Fish Tank Filter is completed, and all parts are connected, you can connect it to the mains. And for the future it should be remembered that any manipulations in the aquarium should be carried out with the filter turned off from the outlet.

How to install a filter in the aquarium and properly exploit it?

Types of filters

Before you install the filter in the aquarium, you need to decide what kind of it is necessary for you. They differ mainly in the method of installation of the filter in the aquarium – to the outer or inner wall (under water). At home most often used compact devices that fit inside containers with water. Their capacity varies depending on the volume of the aquarium. Other species, outdoor or bottom, are used much less frequently, usually with large volumes of water.

The principle of operation is the same for everyone. water under pressure is passed through the filtration material. in which all the dregs linger. Over time, beneficial bacteria multiply inside, which help maintain the purity of the aquarium. In addition, in some filters, special impregnation improves the chemical composition of water. Another important detail: due to the constant mixing of water in the aquarium, there will always be enough oxygen, and the fish will not constantly stay near the surface.

So, most likely, you will be dealing with an internal filter. They are smaller, cheaper and easier to take care of. Bottom now can be found very rarely, and the outside is usually used by professionals.

Filter installation

The tank should be pre-filled with water. Filter must first fully assemble, then submerge (not included in the network) and attach to the inner wall at a distance of about three centimeters from the surface (as a rule, suckers are provided in the design). If the depth does not allow you to do this, simply leave as much distance as possible on top. Below the device should not rest against the bottom. Water evaporates constantly, so the distance should be checked regularly.

The end of the transparent tube that takes the air out of the room must be brought out. It is convenient when there is a special mount on it, with the help of which the tube is held on the glass. If you have already installed aeration system, then this part can not be used. Only after you install the Fish Tank Filter, plug it into a wall outlet. The appearance of the flow indicates that you did everything right. The wire should hang loosely, going down from the socket.

At the hole from which purified water comes, usually a valve is worn, which allows you to adjust the force and direction of flow. Observe how the water moves, and if you want to fix something, unplug the appliance beforehand.

Terms of use

First of all, you need to remember that you can turn off the filter only in order to clean it from accumulated dirt. Do not leave the device turned off in water. moreover, it is impossible to turn on the filter after it has been turned off for some time (half a day or longer), because this is the risk of poisoning your fish. Before you install such a filter in the aquarium, it must be thoroughly washed, and it is better to replace the filtration material.

Before immersing your hands in water, turn off the filter from the outlet. After manipulations (cleaning the aquarium, catching fish and so on) be sure to turn the filter back on .

A filter can only be connected to a network when completely immersed in water. From working outdoors, it will quickly break.

To clean the filter, unplug it from the outlet. Turn off other electrical appliances, and then remove the appliance from the water.

How to install a filter in the aquarium

A filter that purifies water should be absolutely in every aquarium. Otherwise, normal life in a small home pond is out of the question. Special equipment produces mechanical, chemical, and biological water purification. This creates a comfortable environment for the life and reproduction of aquarium inhabitants. Therefore, it’s time to talk about how to install the filter in the aquarium.

Let out internal filters and external. How do they differ from each other and how to set each correctly – we will consider further.

Internal filter and its installation

This type of water filter is placed only inside the aquarium. The equipment is divided into pump and airlift. Features of each is that they are available to anyone, that is, sold at a budget price. It is therefore not surprising that the internal filters have many drawbacks. For example, devices need to be cleaned every day, they occupy a place in the aquarium, and make a noise.

However, such filters are very common. Before buying from a sales assistant, you need to find out if the model is right for your tank.

Beginners aquarists can not put the internal filter the first time. And this despite the simplicity of the design of the device. However, difficulties can be avoided by knowing how to install the filter in the aquarium. The device is placed in the aquarium, when it is half filled with water, the soil is laid in the home pond and the plants have already been planted. Before you turn on the equipment in the network, you need to collect it according to the instructions and fix it in the aquarium.

It is important to know that the internal filters must be completely immersed in water. Moreover, above the device you need to pour another 2-4 centimeters of water. But to the bottom of the aquarium, he should not get.

As a rule, the device is fixed with suction cups to the glass walls. Included with the internal filter is a small flexible hose. It is necessary for air supply. One end of it is fixed on a special hole in the device, the other is brought to the surface of the water and fixed with a special attachment to the upper edge of the aquarium wall. The hose must be above the water level, otherwise the air intake will not occur correctly.

On the hose or on the filter itself there should be an air supply regulator. On how it is located, depends on the strength of the flow in the aquarium, which creates equipment. Once the filter is installed, it is best to set the regulator to the middle position. Next you need to follow the fish. One might like a strong current, and the other way around, and they will start hiding him.

The aquarist should remember that the internal filter can only be turned on when it is fully immersed in water. But before you remove the filter from the water, it must be de-energized. It is important to remember that it is not recommended to leave the device turned off in water. Moreover, you can not turn it on after idle time, if it has not been cleaned.

External filter and its installation

External filter differs from internal one, first of all in price. The purchase and maintenance of such a device severely hits the wallet. However, financial costs are more than offset by the numerous advantages of equipment. The main one is filtering materials and special fillers, which do not need to be changed often.

The external filter will not be annoying, because it works almost silently, it is especially noticeable if it is designed for large aquariums, in volume from 40 to 80 liters. In this device, biological filtering is already provided.

It is worth noting that usually such filters are acquired by experienced aquarists, since several important rules must be followed while working with the device.

The external filter works according to the following principle: the water from the aquarium flows slowly through a special tank of the device, which is filled with filler with filtering materials, then this water is returned through the hose back to the aquarium.

Cleaned external filter is quite different than the internal. And it is necessary to free it from dirt only in aquarium water (it is drained into a separate container). Here you need to completely replace the filter material. This is done in stages. This is necessary so that the biological equilibrium is not disturbed in the aquarium.

Before you install the filter in the aquarium, you need to study the accompanying instructions and strictly follow the recommendations. First you need to assemble the filter, put in place all the fillers and internal sponges. At the same time both cranes, where the hoses are to be connected, must be closed.

The internal filter will work properly and clean the aquarium, if it is installed significantly, below the water level (not higher than 20 centimeters). Together with the external filter are two hoses, they are designed for water intake and its release. Both must be mounted at opposite ends of the aquarium.

As soon as all elements are connected to the device, the filter should be filled with water from the aquarium (for this purpose, gravity flow is used). Otherwise, the air that is in the hoses may interfere with the operation of the device.

To release the air plugs, you must first connect and open the water intake hose. Wait until the filter is full. Water can flow out of the hole for the second hose, so you need to be careful here and prevent this. As soon as the filter is complete, it is necessary to block the inlet hose.

Next, a hose is connected that releases water, its valve closes and the hose is filled with water. Only after these manipulations can you connect it to the water drainage system from the aquarium. Following it, it is already allowed to open both taps and plug the filter into the socket. And here the main thing to remember, only with the observance of all the rules, you can count on the proper and productive operation of the filter. So to guarantee the inhabitants of the aquarium comfortable conditions.

Water filters are among the equipment for the aquarium, without which the maintenance of fish is impossible. Filters remove sludge particles from water, if necessary, alter the chemical parameters of water, adjusting its hardness and acidity, remove drugs and products of nitrogen metabolism of fish and other aquatic inhabitants. There are internal and external filters, so consider the installation process of each of them in more detail.

Installing the internal filter in the aquarium

This type of filter is placed inside the aquarium. Internal Fish Tank Filters are airlift and pump action. This equipment is one of the cheapest, but has several disadvantages. For example, the device requires regular weekly cleaning, takes up space in the aquarium and creates a certain noise, but still such filters are considered the most common. When buying a particular model, be sure to specify whether it is suitable for the volume of your aquarium.

Despite the fact that the design of the internal filter is quite simple, novice aquarists may encounter some difficulties when installing it. This device is installed when the ground is laid in the aquarium, the plants are planted and it is half filled with water. Before connecting to the network, the device must first be assembled and installed in an aquarium.

The internal filter is immersed in water completely, so that from 2 to 4 cm of water remains above it, and it should not touch the bottom of the aquarium. The device is attached to the walls of the aquarium with suction cups. It also comes with a small flexible hose. This is an air supply hose. One end of it is fixed on the corresponding filter hole, and the other end is brought out and fixed on the upper edge of the aquarium wall on a special attachment. For air to be drawn correctly, the hose must be above the water level.

On the air supply hose or on the innermost filter there is an air supply regulator, the position of which will determine the flow force created by the filter. To begin with, it is recommended to set the regulator to the middle position, and after watching the fish – some of them may like a strong current, and some will on the contrary hide from it.

Remember that you can turn on the filter only when it is completely immersed in water, and before you get it out of the water, you need to disconnect the device from the network. Do not forget that you can not leave the filter turned off in the water, and even more so to turn it on after being idle without prior cleaning.

Installing an external Fish Tank Filter

In contrast to the internal external filter for the aquarium and its maintenance is much more expensive, but this is offset by the advantages of such a device. Its fillers and filter materials do not need frequent replacement, the device works quietly, especially if it is designed for 40-80 liters, and biological filtering is present in this filter. This type of filters is used only by experienced aquarists, because during the operation of the device it is important to follow a number of rules.

The principle of operation of the external filter is based on the passage of a slow flow of water from the aquarium through a special filter container with a filler and filter material and the return of this water through the outlet hose back to the aquarium. Cleaning of such filters should be done only in the water drained from the aquarium, the complete replacement of the filtering material is carried out only in stages, so that the biological balance in the aquarium is not disturbed.

When installing this type of filter, be sure to follow the instructions for the device. First you need to collect the filter itself and all of its internal sponges and fillers, while blocking two cranes to which the hoses will be connected. Such a filter is set only significantly lower (not less than 20 cm) water level. The external filter kit will have two hoses for intake and discharge of water. They must be mounted in different ends of the aquarium.

After connecting all the elements, the filter must first be filled with aquarium water using a drift, so that the air in the hoses does not interfere with the operation of the device. To do this, first connect and open the water intake hose and wait until the filter is full. Ensure that no water flows out of the hole for the second hose. When the filter is full, turn off the inlet hose. Then connect the hose to release the water, turn off the valve, fill the hose with water and only then connect it to the outlet in the aquarium. Only after such manipulations open both valves of the filter and connect the device to the electrical network.
