How to mount the internal filter

First, the device must be assembled according to the recommendations set out in the instructions for use. I can’t wait to test it in work as soon as possible?

There is no need to rush, as the filter must first be properly fixed in an aquarium filled with water. over, beginners, as a rule, have some questions. To what depth should the “glass” be immersed? What is the plastic flexible transparent tube for??

The vast majority of internal water purifiers are vacuum-attached to the aquarium wall using special suction cups. These suction cups are included in the scope of delivery. Prerequisite: the filter must be completely immersed in water, the height of the water level above the upper point of the device must be from 2 to 5 cm.

A transparent flexible tube is used to supply air to the device and is connected to its “spout”. The other end of the tube should be outside the aquarium, outdoors.

It would seem that you can already start the “glass” in work. However, experts recommend making the first turn on, removing all living creatures from the aquarium. You never know what! What if there is a manufacturing defect in the device? It is better not to risk it and move all the fish for a short time to a small sump. If the first start-up showed the normal operation of the technical device, the pets can immediately be launched into their water house.

After switching on for the first time, it is recommended to set the power regulator, which is available on each filter, to the middle position. You need to observe the condition of your pets for some time and then empirically set the optimal power of the filtering device.

Accessibility for service and cleaning

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


The basic version of the internal filter for the aquarium. For its implementation, no devices are required, since this is the main thing for which we use the filter. Without water circulation, there will be no water flow, which means that filtration will not take place either. A non-circulating filter does not fulfill its primary function. Sometimes an expanding nozzle is included with the product, which forms a wide flow of water, which reduces vortex flows in the aquarium while maintaining the original performance. In addition, this use case is also the most preferable from the point of view of noise. However, when using the filter in circulation mode, it is worth taking care of organizing aeration (at least at night) using a compressor or an additional aerator pump.

Lack of stagnant zones

Placement of the filter in the aquarium should eliminate the presence of stagnant zones. This means that the filter must create a flow of water in the aquarium of such a force and direction that there are no areas or zones in the entire volume where there is very little or no water flow. This ensures that the entire volume of the aquarium will be served by the filter. It is unacceptable that only part of the internal space is 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 of very long, it will be reasonable to use several filters installed on opposite sides. Many modern filter models are equipped with a number of devices that help to implement this rule. For your convenience and customization of devices for specific conditions, manufacturers equip filters with flow regulators, swivel heads and diffusers to move water in the direction you need.


The capacity of the internal filter for aquraium is determined by the amount of water in liters passed through the filter element per unit of time. It is the main unit that determines 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.

Modes of operation

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

General information

It just so happened that due to their availability, compactness and ease of use, as well as installation in an aquarium, pump filters become the first filters for beginners. There are a huge number of models produced at the moment. But today we will not dwell on the choice of a specific model. The instructions for installing an internal filter for an aquarium are designed to answer the question of how to correctly install an already selected and purchased filter in an aquarium.

Any internal filter pump consists of two parts: a motor pump and a filtering part. The motor pump is the very 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 purifying water from turbidity and suspended particles. By design, all internal filters are made in a sealed design, so the only way to use them is to completely immerse them in water.

Suction cups

Attachment with suction cups is the simplest and most effective. This option allows you to easily remove the filter from the water. The suction cups are located on the body of the device itself and are removed from the aquarium with it, or they are 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 reliability of the fastening decreases. In this case, they are replaced with new ones. In addition, the filter, which is installed on the suction cups, not on clean glass, but on a bacterial film, tends to slip off from its original location. Therefore, the place where the filter is installed must be thoroughly cleaned of slippery deposits.

Realization of goals

The installation of 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 additionally install a compressor, then at least a special nozzle must be included in the device. As a rule, the additional purchase of non-included accessories can bring additional difficulties in finding original accessories or selecting compatible ones. The next question, which will be answered by the instructions for installing an internal filter for an aquarium, is:

Phyto filter

Do not bundle the phyto filter with a biological purifier. The phyto filter principle is that vegetation does not grow in water, but on the surface. And only its roots are in the water, purifying it.

properly, install, internal, filter, aquarium

The simplest structure of a phyto filter is a tray with plants attached to the wall of the aquarium. Ordinary indoor vegetation is planted in a prepared nutrient medium in a tray with holes. Then the tray is fixed to the wall of the aquarium, and the water flow from the aquarium passes through it.

Another variation of this attachment is the vegetation reservoir integrated into the aquarium lid.

The essence is the same: the plant roots planted in a coarse-grained substrate are directly associated with the water in the aquarium and absorb harmful (but useful for themselves) compounds from it.


The device for biological cleaning of the aquarium functions by special bacteria that absorb hydrogen nitride, which forms during the life of the inhabitants.

You can easily make a biofilter yourself. And we will consider the installation of a homemade model called “bottle”. Its size depends on the volume of the aquarium.

To install such a device:

  • make holes in the lower area of ​​the bottle so that the water gets inside;
  • wrap this place with elastic polyurethane foam (foam rubber);
  • secure with plastic clamps to prevent unnecessary contamination of the gravel;
  • pour about half of the filler into the bottle;
  • lead the compressor aerator tube through the throat from above;
  • thanks to the “airlift”, water will be sucked out of the bottle, and fresh untreated water will arrive through its bottom.

Where to locate?

Determining the correct location for the filter element depends on the characteristics of the aquarium, its size and configuration. As a rule, filtering devices are fixed to the side wall of the tank, near the rear window, so as not to interfere with the life of local inhabitants. If the filter element is internal, then it has a special mark on it, which means that it is forbidden to dive too deep so that it does not touch the bottom.

If the depth is shallow, then try to leave a large distance in the upper part, but under no circumstances should the device be at the bottom. The water will always evaporate, therefore the location of the filter must be constantly monitored.

Preparatory stage

The preparatory process includes several steps.

  • First of all, you need to prepare dry rags, because not every time it is possible to eliminate water leakage.
  • We release the device from the packaging and take out all the contents. Without fail, the complete set must include: the device itself, fillers, plastic water outlets, internal sponges, hoses.
  • Before assembly, it is necessary to check that all components are perfectly dry. The assembly of the external (external) filter is carried out according to the manufacturer’s instructions. Be sure to follow the established procedure. The taps on the lid must be in the closed position.
  • Now you can start preparing the external elements so that you can release and take water. The element of the fence is a long tube, rounded at the end. One end of it must be lowered into the aquarium. The evacuation device is a curved short tube, which is installed at the other end of the aquarium. It is imperative to measure the size of the tubes so that their length is sufficient to the curbstone.
  • Before installing the device, it is necessary to fill at least 50% of the aquarium with water, since the cleaning equipment is used exclusively filled.


The bottom water filter should be placed at the bottom of the aquarium. This type is chosen by owners of large aquariums with a small volume of underwater flora. The device itself looks like a thin plate with a filter filler, and a large number of holes through which water passes.

A large number of aquarists believe that just sitting on the bottom is enough for the eyes. Nevertheless, the filter needs to be mounted, and not placed on a substrate.

Aquarium Bottom Unit. Installation Procedure:

  • all soil is removed from the selected site at the bottom of the aquarium so that the base is 100% exposed;
  • the bottom filter is carefully placed on the bottom;
  • the device is covered over with soil so that the device does not spoil the look of the aquarium;
  • launch the device.

Installation of different models

The range of filters is very large, so you need to learn all the nuances of installing various types of filters.

How to properly install a filter in an aquarium?

The aquarium filter is an indispensable element in any aquarium. It performs mechanical and biological purification, and also promotes oxygenation. The choice of filters in retail outlets is huge, so it will not be difficult to purchase a device. But with mounting, problems may appear. Installing an aquarium filter element is a real challenge for most inexperienced aquarists.

Alas, it is not always possible to navigate the intricacies by the annotation attached to the aggregate. The installation procedure will be different for internal and external (external) filter elements, but anyone can really handle the task.


Installing the filter element in the aquarium is not a particularly difficult procedure, you just need to calculate where this equipment will be placed. As a rule, it is located in a cabinet under the aquarium, for this, holes are drilled in the back of the furniture, required for routing the hoses.

The filter will need to be assembled in strict accordance with the practical guide. All sponges and a specialized nutrient medium (substrate) for biochemical water purification are placed in the filter cavity. In the aquarium, pipes are placed at the inlet and outlet, which must be submerged. With the correct installation of the filter in the aquarium, the equipment should be located below the bottom level, which will make it possible to guarantee maximum pump performance.

The filter must be installed in its permanent place, then, by means of a manual mechanical pump, bleed the system, trying to remove air from the pipes and housing as much as possible. Only a few strokes of the mechanical pump are necessary, as a result of which the liquid medium will spontaneously move along the inlet tube, expelling air from the filter element. After the body is completely filled with water, air will stop coming out of the outlet tube.

Now you can connect the equipment to the mains and test the efficiency of its functioning.

If the filter does not start or operates at low power, this indicates the presence of an air lock in the system, therefore, it will be necessary to remove air from the pipes and the housing. For this purpose, already on the operating filter, press the key of the mechanical pump several times, which makes it possible to squeeze air out of the system.

A small amount of air may be trapped inside the case and begin to gurgle. In order to finally do away with such small bubbles, you must carefully pry the filter and bend it from side to side.

Having started to work at its full capacity, the device immediately activates the implementation of mechanical water purification. But biochemical filtration, when nitrates and nitrites are removed, starts approximately one month after the start of the equipment. During this period, colonies of chemosynthetic bacteria will settle on the nutrient medium used, which are responsible for the chemical purification of water.

Actually, for this reason, if possible, it is necessary to populate fish (exotic species are especially demanding) a few weeks after the installation of the external filter in the aquarium is completed.

How to install a filter in an aquarium?

An aquarium filter is a necessary and very important part, as water filtration in an aquarium is a vital procedure for any aquarium. Today manufacturers offer a huge selection of a wide variety of filters. It is when choosing and installing a filter that beginners usually face the first difficulties when starting an aquarium. In this article, we will give small tips on how to install a filter in an aquarium, how often to change a filter in an aquarium.

Filters for an aquarium are divided into two types. internal and external and perform several functions at once:

Purification of water from mucus, turbidity and other organic residues.

Restoration and purification of water from waste products of the inhabitants of the aquarium.

The internal filter consists of a pump that pumps water through a cassette filled with filter material. Installed inside the aquarium and attached to the glass with hooks or special suction cups. The filter can be mounted both vertically and (if necessary) and horizontally.

All filters contain special filter material (foam rubber, sponge, synthetic threads, etc.). It is in the filter, directly in the material, that beneficial bacteria, very important for the life of the inhabitants of aquariums, settle. utilizing organic matter, processing chemicals and destroying toxic compounds.

The main thing is to determine which filter and with what performance you need for your aquarium. It is important to consider some features here: the volume and size of the aquarium, the number of fish and plants that you plan to keep, the movement of water. It is important to provide such water circulation that will allow all the inhabitants of the aquarium to feel comfortable and they will be able to move freely throughout its area.

And to avoid undesirable situations (when the fish rush around the aquarium due to too high a flow rate), install a filter with a flow rate adjustment. Internal filters are ideal for small aquariums, they are quite inexpensive, absorb a minimum of electricity, and they can be installed without problems, even beginners when starting up the aquarium (after reading the instructions).

External hinged filter is a multi-sectional housing, inside of which there are cassettes with various fillers, attached to the side or rear wall of the aquarium (without taking up space inside).

Most models have the ability to replace filter elements (foam rubber, synthetic winterizer). Very easy to maintain, but it is necessary to control the water level in the aquarium. The jet from the filter diminishes as the water level drops, so watch and add if necessary.

An external canister filter is a more sophisticated device for filtering water in aquariums. Consists of a canister with filter media and a removable lid.

Due to its large size, it is installed outside the aquarium (without fail below the water level) so that water flows back into the device, it has several stages of cleaning. It is used for aquariums of large volumes, keeping more demanding fish and can work for a long time without special maintenance.

For such filters, periodic control is required, checking the fastenings of all elements (in order to avoid leakage). Try to buy such filters only from reliable companies that provide their customers with further service.

There is no single and precise answer to this question. Everything, or at least a lot, depends on each individual aquarium. After all, each aquarium is unique in its own way (the composition of the water, the number of fish, their type, the feeding ration and regime, the frequency of water changes, soil cleaning).

Considering all this, it is impossible to say unequivocally how often the filter needs to be flushed. Many do it simply, remember the strength of the water jet in the newly installed filter, and as it decreases, they realize that it is time to flush the filter.

It is necessary to flush the filter elements very carefully (preferably in aquarium water), removing the necessary sludge excess, trying as little as possible to harm the bacteria colonies living there, and especially take these conditions into account if your aquarium is recently launched. It will be very correct if you make it a rule to check the condition of the filter and, if necessary, clean it at each water change.

And in the end, one more very important advice that beginners sometimes forget about. the filter must work constantly. It is necessary to turn off the filter only at the time of its cleaning and rinsing of the filter elements.

How to install a filter in an aquarium

A filter that purifies water should be in absolutely every aquarium. Otherwise, there can be no question of normal life in a small home reservoir. Special equipment produces mechanical, chemical and biological water purification. This creates comfortable conditions for life and reproduction of aquarium inhabitants. Therefore, it’s time to talk about how to properly install the filter in the aquarium.

They produce internal filters and external ones. How they differ from each other and how to correctly install each. we will consider further.

Internal filter and its installation

This type of water filter is only placed inside the aquarium. The equipment is divided into pump-action and airlift equipment. The peculiarities of each is that they are available to anyone, that is, they are sold at a budget price. Therefore, it is not surprising that internal filters have many disadvantages. For example, appliances need to be cleaned every day, they take up space in the aquarium and make 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 aquarium.

Novice hobbyists may not install the internal filter the first time. And this is despite the simplicity of the design of the apparatus. However, the difficulties can be avoided by knowing how to properly install the filter in the aquarium. The device is placed in the aquarium when the on DO half is filled with water, the soil is laid in the home reservoir and the plants have already been planted. Before connecting the equipment to the network, it must be assembled according to the instructions and fixed in the aquarium.

It is important to know that the internal filters must be completely submerged in water. over, another 2-4 centimeters of water should be poured over the device. But he should not reach the bottom of the aquarium.

As a rule, the apparatus is attached to glass walls with suction cups. A small flexible hose is included with the internal filter. It is required for air supply. One end of it is attached to a special hole in the device, while the other is brought out 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 be correct.

There should be an air regulator on the hose or on the filter itself. How it is located determines the strength of the current in the aquarium, which the equipment creates. Once the filter is in place, it is best to set the regulator to the middle position. Next, you need to follow the fish. Some may like a strong current, while others, on the contrary, and they will begin to hide from him.

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

External filter and its installation

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

READ  Do-it-yourself internal filter for aquarium

The external filter will not be annoying, since it works almost silently, this is especially noticeable if it is designed for large aquariums with a volume of 40 to 80 liters. In such a device, biological filtration is already provided.

It should be noted that such filters are usually purchased by experienced aquarists, since several important rules must be followed while working with the device.

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

The external filter is cleaned in a completely different way than the internal one. And you need to free it from dirt only in aquarium water (it is poured 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 balance is not disturbed in the aquarium.

Before properly installing 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 all the fillers and internal sponges in place. In this case, both taps, 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 (no higher than 20 centimeters). Together with the external filter, there are two hoses, they are designed to take water in and out. Both should be mounted at opposite ends of the aquarium.

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

To release the air s, you first need to connect and open the water intake hose. Wait for the filter to fill. Water may leak out of the hole for the second hose, so be careful not to let this happen. Once the filter is full, shut off the inlet hose.

Next, a hose is connected, which releases water, its valve is closed and the hose is filled with water. Only after these manipulations can you connect it to the water drainage system from the aquarium. Next, it is already allowed to open both taps and plug the filter into the outlet. And here the main thing to remember is that only if all the rules are observed, you can count on the correct and efficient operation of the filter. This means to guarantee comfortable conditions for the inhabitants of the aquarium.

Determine the ability of the filtering device to pump a certain volume of water. Manufacturers indicate performance parameters on packaging labeling, in instructions.

Important. It is necessary that the filter be able to pump from 4 to 10 volumes of water per hour of the capacity of the entire tank. That is, they buy a filter with a power calculation that exceeds the specified performance several times.

If you use insufficiently powerful filters, stagnant zones will form. Disruptions in water circulation lead to a decrease in oxygen levels. Water can bloom, become cloudy.

Filter types

There are internal and external filters. The former are installed inside the water tank, the latter outside the tank. Devices function on a similar principle.

At the bottom of the aquarium, bottom filter systems are installed on a special mesh. Air is circulated through tubes that run along the bottom of the aquarium. For proper functioning, it is necessary to select the right soil. It should not clog the pipe inlets. The disadvantage of this type of filtration is that the water must be drained to install and clean the device. Move the fish temporarily to another container.

Popular internal filters with mechanical, combined cleaning. Easy to install, clean effectively. The disadvantages include the fact that they take up a lot of space in the aquarium, they are striking.

External hinged filtering devices are installed outside the aquarium. Some types are mounted on the back or side wall. They work on the principle of glass internal filters. Water is sucked out of the container, which passes through the filter layers. Enriched with oxygen from the air, returned back to the aquarium.

Important. External canister filters with several stages of cleaning show a good result. Due to the larger volume, the number of filter elements, external filters efficiently purify water.

Large dimensions are a disadvantage.

It is better to disguise the container with cartridges. Usually installed in a closed cabinet below or next to the aquarium.


Unpack the package, check the package contents.

  • According to the instructions in the sequence described, the filter is assembled.
  • Immerse the flask in water so that it is at least 2 cm covered with water, not plugging it into the outlet.
  • The external pipe aerator is brought out and fixed on the tank wall.
  • At the time of the test run, it is recommended to plant the fish from the aquarium.
  • Connect the filter to the mains, the wire should hang freely.
  • When the device is working, you can see the bubbles in the water.

After installation, the flow rate is regulated by a valve on the air intake pipe. Optimal position. middle.

We place in nano aquariums

Nano aquariums are small ecosystems up to 40 liters. Air-lift filters are used for water purification. The difference from pump pumps is that they are less powerful, small in size, and affordable. The compressor pumps air, the bubbles, together with particles of aquarium debris, rise up to the tube on which the filter is put on. It is better to put it on the side wall. Compact corner models are produced.

How to mount the internal filter

Check the package contents before installation. In addition to the two main pipes, there must be a pipe for filling the canister with water.

  • Water leaks may occur when filling the canister, prepare a cleaning cloth.
  • According to the instructions, in the specified sequence, collect all the elements of the filtering system.
  • The bent end tube is designed for water intake.
  • Lower the tube into the aquarium with water, open the tap valve, fill the canister with water cartridges.
  • Water flow must not flow out of the second hole.
  • When the canister is full, close the tap.
  • The hose coming from the aquarium is connected to the filter.
  • Suction the air slightly so that the pipe fills with water.
  • Connect the second, outlet hose.
  • Open the incoming taps on the canister.
  • Plugged in.
  • Circulation of water indicates correct connection.

Canister type external filter systems are mainly designed for large aquariums with seawater. Thanks to a multi-stage cleaning system, they are of the highest quality.

Step-by-step instructions on how to properly install the filter in the aquarium

An aquarium is not just a decorative element, it is an ecosystem. In order to admire the floating fish in clear water, they need to be provided with optimal conditions: lighting, heating, oxygen access. An aquarium filter is one of the main elements of the functioning of an artificial indoor reservoir. Cleans water from mechanical debris, fish waste products, regulates biological balance, saturates the water with oxygen. Instructions on how to install the filter in the aquarium so that it functions correctly will be presented below.
