How does the aquarium inlet pump work?

The principle of operation of the aquarium water pump is very simple. Through the tube enters the air air, the pressure of which is regulated by means of clamps and valves. Absolutely different parts of the water pump are responsible for the bubbles. These are sprayers attached to the airway tubes.

They create small bubbles, which are also decorative decoration, especially in combination with the backlight, as seen in the photo. Sprayers are located at the bottom. Each rising bubble mixes the water, equalizing its temperature. In addition, the bacterial and dust film on the surface is destroyed.

If the aquarium is populated with fish and plants in a small amount, then the time of the water pump can be determined independently. It is not necessary to keep the equipment on all the time. Watch the behavior of the fish.

If they start to get enough air, especially from the surface, then immediately turn on the water pump. It is better to leave it in working condition and night. Plants emit carbon dioxide – if the aquarium is densely planted with them, the inhabitants of the reservoir may not live until morning.

The air pump for the aquarium is designed to provide enough comfortable conditions for the fish to live. This equipment conducts additional aeration of water, regardless of the capacity of the aquarium.

But first you need to choose the right water pump. But how to do it? Which is better? After all, there are several different types, in addition, each manufacturer offers its own models with individual characteristics. Therefore, it is important to understand what you should pay attention to when choosing a water pump.

How long should the water pump be turned on? In our opinion, it should be in working condition around the clock. For example, water pumps have been running continuously for several years now.

However, if you are not sure of your water pump (or save electricity, although water pumps consume microscopic power – no more than 5 W), turn it on periodically – 2 hours on, 2 hours off. Be sure to turn on the water pump after feeding the fish.

For reinsurance, be sure to turn on the water pump at night. An amateur constantly appealed to us, whose fish perished steadily. He tried to heal the survivors, often changing the water. Finally, the “secret” opened up: the unfortunate aquarist admitted that he had turned off the water pump for the night. That was the deplorable result of his savings.

Hoses and sprayers

Polychrocenilles can be used as air ducts.

, and better – tubes from medical systems – droppers. Such ducts are transparent, which does not spoil the aesthetics of the aquarium, have intensity regulators (clamps or faucets), do not emit harmful chemicals into the water.

We do not recommend using black, red, brown rubber hoses, in order to avoid poisoning fish with substances secreted by rubber.

To maximize the saturation of aquarium water with oxygen, it is necessary to break the air stream into multiple bubbles using sprayers. They can serve as special stones of porous structure.

Currently, there are long, often in the entire rear wall of the aquarium, tubular

. They create a uniform air wall along the entire length of the smallest bubbles, which looks very impressive and useful for fish.

Note that the smaller the air bubbles, the more efficient the operation of the water pump. Sprayers must be installed in the aquarium near the bottom, for greater decoration, they can be masked with stones and other elements.

Such devices are also called aerators. Most of them are vibratory machines. The principle of their operation is based on the creation by an alternating current of an electrical network of an alternating magnetic field.

Novice aquarists should be guided in how to choose the right water pump for arranging your aquarium. After all, the market is saturated with a huge range of such products. To understand the choice is not easy.

First of all, we must understand that each such device is designed for a certain amount of water. It is necessary to choose it, proceeding from its thickness. A powerful water pump is needed only for aquariums with a large volume of water.

How to correctly focus on the performance of the device? Calculate it simply. It is necessary to multiply the displacement of the aquarium by 0.5 So, on a one-hundred-meter fish house you need an aerator with a capacity of 50 l / h.

For home fish houses often use submersible devices with lighting. They are installed inside the tank. This gives the fish house aesthetics, decorative. At night, a room with such a fish house is filled with a soft light.

If the owner has a need to urgently transport the fish, then a water-powered pump is used. Such a device will be indispensable in situations where power outages are often practiced in the home or office.

If we talk about external water pumps, they are good for aquariums because they are compact, do not clutter up space, are conveniently mounted and easy to use.

Today, small and silent water pumps for the aquarium are very popular. They are recommended to be used in those containers whose volume does not exceed 200 liters. That is, they can be used in the most popular metropolitan fish houses.

Such devices are recommended to be included in the morning and in the evening. There is no need for the device to work all day. Such mini-water pumps are actively used for decorative purposes, because many people are attracted by the appearance of flowing oxygen bubbles.

In large aquariums, water pumps create optimal, close to natural conditions for waterfowl.

So, the purpose of the water pump is to saturate the water space with oxygen. Today, an alternative to such a device is the saturation of water with dissolved oxygen using the so-called oxidizers.

Choose the correct mode and brightness of the lighting!

Illuminated almost around the clock aquarium looks very beautiful, but it can lead to various unpleasant consequences. Depending on the selected fish and plants, daylight hours in an aquarium should usually not exceed 10 hours. If it lasts too long, bacteria and algae will actively develop.

It should also be properly installed aquarium. It should be in such a place that direct sunlight would not fall on it, otherwise the vessel walls will be overgrown with algae.

If there are no live plants in your aquarium, reduce the duration of illumination to a minimum, as the fish do not particularly need it. To control the length of daylight hours, you can use a timer that will turn the lighting equipment on and off at a specified time.

Once a week make water changes!

In order for the inhabitants and the vegetation in your tank to be healthy, it is necessary to carry out a water change properly. It is absolutely not necessary to completely change all the water in the tank. It is enough to do every week substitute a quarter or third of the volume of the aquarium.

To do this, you can use cold tap water, which must be allowed to stand for at least a day. A good solution is to use water conditioners, thanks to which tap water will become suitable for an aquarium. If there are no live plants in the vessel, you can siphon the primer at the same time as changing the water.

And remember! Whatever the good filter, water change still remains a prerequisite for the care of the aquarium! By doing it, you get rid of the waste products of living inhabitants, and also saturate the water with nutrients necessary for microorganisms and plants.

Test your water regularly!

As a rule, novice aquarists are not aware of such a phenomenon as the nitrogen cycle, and also do not know that it is extremely important to test the parameters of water in an aquarium. Conducting such tests is necessary to monitor the level of toxins in the water.

Having established an aquarium, it is necessary for it to allow to stand several days. Then proceed to monitor the pH, hardness, nitrite content and ammonia. Their level should be within the normal range.

First, you need to test water for nitrites and ammonia quite often. When the aquarium is already filled with vegetation and fauna, water should be checked once a month to avoid problems.

If you started to die fish, first check to see if the water parameters are normal.

Pick a filter of suitable volume!

Do not forget about the timely cleaning of the filter!

Regardless of the type of filtering system used (internal or external canister filter), it is important to properly maintain it.

Remember! In no case should the filtering material be rinsed with tap water. For this purpose it is necessary to use only aquarium water. Otherwise, you will destroy the microorganisms that live in the filter, the task of which is to purify water.

Do not be afraid of "dirty" filter sponges. There is no need to clean the filter too often. Focus on the flow of water through it and its transparency.

Do not turn off the aquarium equipment at night!

Imagine that you live in hot Africa, and, going to bed, not only turn off the lights in the house, but also turn off the air conditioner, closing all the windows tightly. If you are a thrill-seeker, then, of course, you can experiment on yourself, but don’t do it better with fish!

Remember! The water pump and pump filters cannot be turned off at night. If you do not like the fact that the water pump is constantly buzzing, you can try to install an internal filter in the aquarium. If the water pump can make distracting and annoying sounds during operation (by the way, high-quality products from well-known manufacturers will please with their relatively quiet operation), then modern filter pumps are virtually silent.

Aeration in the aquarium and everything you need to know about it.

The answer is obvious to everyone who has seen this device in operation: it increases the oxygen content in aquarium water. Water in a stationary state may eventually turn into a kind of swamp.

Remains of vital activity of small fish, grain of feed, dust, small debris, film on the surface, lack of oxygen can all lead to an unfavorable state of the aquatic environment.

And, as a result, to the disease, and in the worst case to the death of the inhabitants of the aquarium. The air pump, supplying air to the water, enriches it with oxygen, creates air and water flows. This process is called aeration, and such water pumps are sometimes called aerators. Simply put, this is an air pump

.The main requirements that must be placed on the device when choosing it

Often the aquarium is in the same room where people relax. Therefore, for the aquarium it is better to choose a silent water pump. This device operates continuously. To reduce the noise level of the device, you can remove it into the cabinet.

But then you need too long duct. Therefore, it is worth thinking carefully before making the water pump silent, by isolating it. It is better to purchase a silent device at once. The air pump for the aquarium is the most silent.

0.5 l / h per 1 l of water. This is the way to solve the question of which water pump is better suited for a specific tank capacity. For a large aquarium (over 100 liters) use a piston water pump.

For such an aquarium, it is better to take a device with low-voltage power (12 volts). In the event of a power outage, it can be connected even with a car battery. You can make a quiet water pump using old equipment yourself.

So, in order for a home-made device to work as quietly as possible, you will need a wooden box and a box from under the film. In this case, a quiet water pump is obtained by compensating the shock wave with a jar. The very same self-made water pump hides in a wooden box.

Fish breathe oxygen and exhale carbon dioxide, which plants consume during the day of photosynthesis, releasing oxygen. Plants play a major role in maintaining the required amount of oxygen.

Different plants supply different amounts of oxygen. If the ratio of plants and fish in the aquarium is chosen correctly, then both gases are sufficient for them, and they feel great. If there are few plants and many fish, then the latter lack oxygen, in which case the aquarist resorts to aeration.

Aeration performs the following tasks:

  • Saturates water with oxygen.
  • Creates a circulation of water in the aquarium.
  • It equalizes the temperature in the whole aquarium.
  • Destroys the bacterial and dust film formed on the surface of the water.
  • Simulates the necessary environmental conditions, such as flow. These conditions are necessary for some species of fish.

But if you have a lot of plants in the aquarium, you can not use aeration. aeration is used to remove excess carbon dioxide. Our industry produces various types of micro water pumps powered by AC power.

The drive in them is an electromagnet, which informs the lever connected to the rubber membrane, 50 reciprocating movements per second. They provide performance up to 100 liters per hour.

aquarium aeration

When you turn off the pump, water can rise through the hose and, if the pump is installed below the water level in the aquarium, then, according to the principle of communicating vessels, it enters the pump and spills onto the floor of the room. Vibro water pumps need additional inventory, such as a hose and a suction cup, and clamps to adjust the air supply.

Foreign companies produce various air pumps with a capacity of 1 to 100 liters per minute. But you should not choose too powerful water pump for your aquarium, because it can cause stress to the fish.

The volume of the aquarium that this or that water pump is designed for is usually indicated on the package. For example, the FAT-mini filter aerator is designed for an aquarium of 30-60 liters, no less than no more. This filter aerator is the weakest of the FAT series, but its performance is from 50 to 250 l / h.

Many models are equipped with a built-in filter. Such water pumps are very convenient. The air in these water pumps is mixed with a water jet directed back to the aquarium, this creates additional airing.

Silent air pump for aquarium: how to choose and install

To maintain biological balance, the aquarium will need help. It is necessary to consider each aquarium as a complex organism, the viability of which can and should be maintained with the help of equipment.

Water pumps belong to the main equipment, as well as filters, water heaters, lamps. What kind of air pump is needed for an aquarium depends on the size of the “reservoir” – the larger the volume of the aquarium, the greater must be the power of the water pump. The water pump aerates the water, that is, saturates it with oxygen.

In the daytime, living plants absorb carbon dioxide and emit the necessary oxygen for plants and aquarium inhabitants. At night, both plants and fish become oxygen consumers, because in the dark time plants do not photosynthesize.

So, at night in the water increases the level of carbon dioxide – an additional influx of life-giving oxygen is needed. Water pumps pump air into the aquarium water. From the side it looks like streams of bubbles that rise from the bottom of the aquarium.

The smaller the diameter of these bubbles, the more gas they give into the water. In addition, a running water pump improves the circulation of water, thereby equalizing the temperature in different zones. How to install a water pump in the aquarium

The water pump is recommended to be installed so that it is above the water level and outside the aquarium. If it is not possible to install a water pump above the water level, it is necessary to additionally equip the device with a check valve.

The check valve prevents the flow of water in the opposite direction – after all, the water pump installed below the water level can start to receive water from the aquarium. So, if the owner does not want to repair his apartment and the apartment of his neighbors below, he must take care that the water does not flow out of the aquarium through the water pump in case of a breakdown or power failure.

It is important and properly install the device. First you need to decide where it will be – above the water surface or in a special tank outside the aquarium. Installing a water pump in an aquarium, especially a submersible one, is also carried out taking into account the need to clean the device – it is important that there be no problems for temporary dismantling.

To eliminate the noise from the device, you can arrange it on foam, and in extreme cases – foam. Air ducts and sprayer are placed at the bottom. The tube can simply press a shell or pebble.

Many manufacturers provide a wide selection of water pump for the aquarium. The acquisition of such a device requires a careful study of the models and their characteristics. The most important ones are as follows:

  • performance;
  • power;
  • the volume of the aquarium;
  • manufacturer.


According to one of the classifications, the water pump for fish can be unregulated and adjustable. In the latter case, the front or side panel of the device has a special regulator. By rotating it, you can affect the performance of the water pump, thereby changing the number of bubbles.

  1. Electronic. It limits the course of the membranes. The disadvantage is that the electronic part is exposed to heat.
  2. Mechanical. The vibrations of the membranes are limited by the feet, or the magnets are moved away from the coil inside the air pump for the aquarium itself.
  3. Overlapping output channel. More common option. In this case, close the valve located at the transition from the duct to the sprayer.


The unregulated water pump is simpler in the device. It has no additional parts that would affect the power of the device and aeration. Performance remains constant, so power consumption rises.

In addition, the noise from such a water pump for the aquarium can not be reduced by reducing its power. Some craftsmen, in this case, independently install special faucets on the air tubes, and replace the aerator itself with an ordinary cooler from a computer.


The principle of operation of this type of water pumps is based on the movement of the piston, which pushes the air out. Rotational motion of the shaft is converted into oscillatory. This leads to the achievement of the desired air supply.

If your fish live in a bedroom or a rest room, then a piston air pump for an aquarium would be ideal in this case. It produces not so much noise, but not so cheap compared to the membrane one. Both types of water pumps can be used at once. Piston to include at night, and membrane in the afternoon. The latter consumes less energy.

The main advantages of a piston pump:

  • durable;
  • almost silent;
  • high performance;
  • suitable for large aquariums.
  • consumes a lot of electricity;
  • expensive.


Otherwise, the diaphragm air pump for the aquarium works. It causes the air to move from the chamber connected to the membrane. It shows pressure drops. They are created by vibrations of the magnet, which also indulge in an elastic rubber membrane.

Its advantage is low energy consumption. In addition, such a device can be repaired, although it is often not necessary. He also refers to relatively cheap devices and can serve more than one aquarium. The disadvantage is low power and high noise.

battery-operated air pump for aquarium

Aerators for aquariums of any type can be powered both from the 220-volt network and from batteries. The latter option is preferable only for traveling a considerable distance, or in conditions where electricity often disappears.

the aquarium inlet pump with batteries is characterized by high cost at low power and high level of noise. They "eat" a lot of energy and work no more than 4-6 hours. Then you have to buy a new set of batteries.

Water pump performance

The main parameter that indicates the amount of air distilled by the device over a time interval. Optimum performance depends on the population density of the aquarium and their species. The value of 0.5-0.8 l / hour per liter of “can” volume is considered traditional.

After a simple calculation, you can determine that for a 100 l aquarium you need a capacity of 50-80 l / h, and for 300 l – 150-240 l / h. The presence of the biofilter in the “bank” increases this value.
