Installing A Water Pump In An Aquarium

Water pump function

There are two arguments to the question of whether you need an air pump in an aquarium:

  1. the filter provides a constant supply of oxygen. Under natural conditions, oxygen saturation occurs due to the flow of water. In an aquarium, the process is carried out thanks to live plants as a result of photosynthesis. But it occurs in the daytime, at night, plants and animals absorb oxygen, while releasing carbon dioxide. And without a water pump for an aquarium in this case can not do.
  2. creates an artificial current that prevents water from stagnating and turning into a swamp. This is due to the accumulation of a large amount of food residues and the vital activity of animals, due to dust and small debris entering the water, formed film on the water, and insufficient oxygen concentration.

Therefore, even for a small aquarium with a small number of animals, an air pump in the aquarium should be installed. Due to its lack of fish in the tank can die from oxygen starvation.

In an aquarium, a water pump creates air and water flows, i.e. a process of aeration takes place. The device itself is often referred to as an aerator.

See how to properly install a water pump.

How much time should the air pump for the aquarium work per day?

The principle of operation is as simple as the device device. Pumps for aquariums are equipped with special tubes through which air enters the tank. The oxygen supply is regulated by means of valves. At the end of the tubes are sprayers that emit air bubbles. They are made of abrasive substance. Sometimes they include a grinding stone.

Air bubbles are created using sprays. They are located at the bottom of the aquarium. During aeration, all layers of fluid in the tanks are mixed, and therefore the temperature becomes homogeneous. This process helps to eliminate the dust film located on the surface.

Installing A Water Pump In An Aquarium

There are special water pumps that simultaneously have a filter – pump for the aquarium. We talk more about them in another article.

Water pumps may differ by the presence of a special regulator. He is responsible for managing the performance of the machine and adjusting the flow of bubbles in the aquarium. The water pump is equipped with a special device, thanks to which the adjustment is made. There are several types of regulation:

  • The mechanical type of regulation is based on the action of the legs or magnets. And their use regulates the oscillation of the membranes.
  • Electronic type limits membrane travel. Among the disadvantages of a high degree of heating element.
  • One of the common types is valve overlap. It is located on the tube, between the air duct and the sprayer. To adjust the air supply to the tank is required to overlap the element.

An unregulated water pump is not equipped with additional elements that regulate it. The device device is simple, but the performance remains unchanged. The disadvantage is the constant noise, which cannot be adjusted by reducing the power of the water pump. It consumes a lot of electricity.

By type of device emit:

The first look is more durable. The principle of its operation is based on the reciprocating movement of the piston, which pushes the air out. The water pump emits little noise, which is a plus of this model. It is well suited for aquariums located in bedrooms or children’s rooms. The model can be installed in tanks with a large volume, as it has a good capacity.

The diaphragm water pump is simpler to install. The principle of its work is different from the first type. This device passes the air flow from the chamber, which is connected to the membrane. Due to the magnet oscillations, a pressure drop is achieved, which leads to the process of supplying oxygen to the reservoir.

You can purchase aerators of two types. It is recommended to install the diaphragm pump in the aquarium during daylight hours. It is possible to attach it to several small aquariums at once. The second type is set at night.

There are aerators that are powered by alkaline batteries. They are thin and make a lot of noise when working. Action time is about 5 hours. Used when moving or lack of access to electricity.

The performance of the water pump plays an important role in the selection. It may depend on the population of the reservoir, as well as its volume. Under the performance refers to the amount of air that surpasses the aerator for a certain period of time. It is calculated by the value, which is 0.5–0.8 l / h per liter of liquid in the tank.

When choosing an aerator, the height of the aquarium is taken into account. The larger it is, the more powerful the apparatus must be, since the incoming air overcomes the pressure of water. Have a role on the power device holes in the sprayer. If they are small, the aerator will need more power to supply oxygen.

Working time depends on the population of the aquarium. Small tanks with a low content of plants and fish do not require round-the-clock aeration.

Work can be adjusted independently. This requires watching the behavior of the inhabitants. If the fish rise to the surface, it is necessary to turn on the device or increase the oxygen supply.

At night, the water pump must work. There are representatives who are nocturnal. Due to the lack of light, plants begin to emit carbon dioxide. Lack of oxygen will lead to the death of the inhabitants of the reservoir.

It is impossible to keep the device permanently on, as the vibration adversely affects the condition of the inhabitants. The exceptions are some species of fish that need round-the-clock aeration.

Each aquarist uses a water pump individually because there are personal requirements for a separate tank.

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.

System selection

Choosing a water pumping system is an important point. Before you choose a device, you should consider a few nuances:

The air filter must be adjustable, that is, it will be possible to set the amount of air supplied. The device is used with any number of filters and sprayers. To choose the right air filter, you should consider the principle of operation of the device, the level of noise. Aquarist divides aeration systems into three types: membrane, piston and pump. Varieties differ in price.

Membrane filter

Membrane installation is suitable if you want to save on electricity rates. The device can be installed simultaneously on multiple tanks. Among the positive aspects there are also a long service life, rare failures and the almost complete lack of need for repairs.

The disadvantage of this water pump is one – it is quite noisy. The reason for this is the vibrations that are formed during the process of contraction of the membrane of elastic rubber, as a result of which the magnet oscillates and transmits movements to it. Thus, air is being forced. A membrane device is therefore often referred to as a vibration device.

You can easily make a quiet water pump aquarium with your own hands. To do this, take a wooden box, packaging from film. Place the device in a box, and with the help of a box the shock wave will be reduced. The water pump will be quieter.

Piston aerator

If you want to purchase a silent air pump for an aquarium, give preference to a piston filter. It works by the piston, which drives the engine. The rotation of the shaft create vibrations that carry out the supply of oxygen. Their intensity depends on the power of the device.

Installing A Water Pump In An Aquarium

In this case, instead of one powerful water pump for an aquarium, two types of aerator can be used at once – a membrane and a piston. Vibration is activated at night, the piston air pump for the aquarium – during the day.

Piston water pumps are suitable for large tanks. Choose a filter that will operate on low voltage power. If a power outage occurs, it will allow the device to start from the battery for the car.

If we compare the cost of the piston and membrane filters, the former is much more expensive, but more reliable and suitable for large tanks installed in rest rooms. In addition, it has a long service life, a high degree of performance. But a piston air pump in an aquarium consumes much more electricity.

The aeration pump coordinates the flow of air in the tanks of different volume, carries water to the filtration system. The pump not only equips water with oxygen, but also contributes to its purification. For large-scale aquariums use a device that carries out a constant circulation of water. The operation of the water pump in the aquarium in the form of a pump is carried out quietly, since the devices are quiet. This is due to the fact that these devices are internal, that is, they are immersed.

Micro Air Pumps

There are types of water pumps that operate autonomously. Power can come from a 220-volt electrical network and from batteries. Mini-water pumps are used when traveling for small tanks. A mini-air pump for the aquarium is also purchased in case of a sudden power outage.

These types of air pump for aquarium have a small power level. It is worth while installing quite expensive. The standalone filter is very loud. Its performance is not longer than 6 hours. After that, the battery charge ends and you have to change the kit. This is extremely unprofitable, so leave the air filter is always on is not worth it.

Another filter characteristic is adjustment. The aerator can be adjustable and not adjustable. On this depends the smoothness of the air flow. In regulated installations it can be reduced or increased if necessary. In unregulated flow of oxygen is fed with the same intensity.

It is important not only to choose a water pump, but also to install it correctly. Before you install a water pump in the aquarium, you should consider a few nuances:

  • Connection begins with a choice of the place for the filter. It can be placed both inside the tank itself, and on the lid of the tank or on the pedestal on which it is located.
  • The installation of a water pump in an aquarium can be either on the surface of the water or with partial or complete immersion. In the latter case, a check valve is installed on the air duct.
  • Next to the water pump, place the aquarium heater. This will allow you to quickly mix the heated water with the cold, and the environment for fish will be more comfortable.
  • In order for silent aeration to take place, polystyrene is preliminarily placed on the pedestal, or the filter is installed in another room, connecting it to the tank with a long hose.
  • Do not forget to periodically clean the water pumping device. Its pollution leads to a decrease in performance. After a while the device will break. Dirty filter and louder.

Why care of the filter is understandable, but how to implement it correctly? This is done like this:

  • in the presence of a filter for air purification, replace it regularly;
  • control the reliability of the membrane parts of rubber and change them in time. If this part breaks, then the entire water pump will most likely have to be changed, as it is difficult to find spare parts for certain models.
  • periodically pull out and wash the diffusers in warm water. This will reduce their resilience and increase the service life of the device.
  • monitor the air hoses. In case of minimal damage, replace them.

Instead of a water pumping system, you can use an oxidizer. It does not need to be plugged into a power outlet and constantly change batteries. In addition, it is the quietest filter for aquariums from all available varieties. It works on chemical reactions: with the help of catalysts, hydrogen peroxide decomposes into water and oxygen. The reaction accelerator can be metals that absorb active oxygen, and the surplus gives into the water.

If it is not possible to purchase a quality water pump, you can make the device yourself and temporarily use it as an aeration system. To create a high-quality filter, you need experience in creating similar devices. Homemade can lead to a short circuit in the water, which can cause the death of not only fish, but also man.

You can make a water pump aquarium with your own hands, but for this you should strictly follow the instructions. In this case, you will not only quickly create a device, but also make it safe. You can build a water pump yourself in several ways. Consider the most simple and affordable:

  • Take a small electric heater and connect it to the mains. The power of the device should not be more than 12 volts. It can be connected to the battery or battery in case of power failure.
    After that, connect the eccentric to the engine. It is necessary for the implementation of the movement of the pump. She, in turn, will carry out the process of circulation of water flows, supplying it with oxygen.
    The advantage of this method is that such water pumps are noiseless.
  • The second method is based on the action of a magnet. Electromagnetic starter must be at 50 Hz frequency. This is enough for 220 volts.
    A pump is attached to the electromagnet. Under its action, the membrane begins to move with the same frequency. Air enters the pump, and as a result, the water is saturated with oxygen. This water pump is quite noisy, consider this fact when choosing a device.

Self-made devices are external. They are attached to the surface of the aquarium or placed in a separate container nearby. The hose and sprayer is placed at the bottom at a slight angle. On the surface they will function poorly. Hoses choose from silicone. They should easily pass the bending and restoring test. This will prevent quick wear. If the hoses harden, they must be replaced immediately.

How long the filter should work depends on how many fish and animals live in the aquarium, whether there are live plants. If the animals are few, keep the supercharger constantly on is not worth it. Set the mode yourself, focusing on the behavior of fish. If they behave calmly, swim in the bottom and middle parts of the aquarium, the filter can not be included.

Continuous work should be if the animals begin to eagerly grab the air on the surface of the water and at night. Otherwise, the fish simply die. Periodically do a test for the presence of nitrates, the concentration of acidity and alkaline balance. This will help in time to monitor the deterioration of the vodshny pumping system and, if necessary, to replace it.

Air pump for the aquarium is a necessary device for maintaining the biological balance of the reservoir and the active life of the fish.

How to choose an air pump for the aquarium

When choosing a water pump for an aquarium, several factors must be taken into account. Not every campaign produces quality products. With a constant supply of oxygen to the tank, aquarium inlet pumps should have good power. When choosing a device you need to pay attention to its performance and characteristics.

Among the well-known brands of aerators are the following:

  1. Schego water pumps.
  2. Collar.
  3. Aquael

water pumps company Schego, which manufactures devices for any type of aquarium. Depending on the volume of the tank, you can purchase a device with different power. Portable Schego optimal aerators are manufactured that are powered by alkaline batteries. They are convenient when moving or lack of access to electricity.

  • The device works silently.
  • The device is equipped with a mechanism that allows adjustment of the oxygen level.
  • High power allows you to set the sprayer to a depth of 5 meters.
  • The model can serve several aquariums at the same time.
  • The dense filter allows to save a spray from hit of dirt and dust.

The Ukrainian company Collar produces good water pumps, distinguished by their reliability. Designed for a small aquarium up to one hundred liters. It can be installed to a depth of 1 meter. The use of a high-precision air chamber made it possible to achieve a low noise level when the device was operating. Quite powerful with compact dimensions.

The air water pump from the company Aquael is one of the most common devices. Takes the leading places in ratings of water pumps. Devices of various capacities are produced, which allows to choose a model for aquariums of any size. Suitable for freshwater and saltwater reservoirs. If necessary, you can replace the prefilter. Equipped with two air channels.

Possesses such positive qualities:

  • Compact size.
  • Low noise during operation.
  • Existence of the valve for adjustment of power.
  • There is an LED indicator that allows you to track work.
  • Low power consumption.

It is necessary to approach the choice of the aerator with care. Some models can not equip the tank with the necessary level of oxygen, because they do not have the necessary power. The noise level and dimensions of individual models are not suitable for some aquarists. Studying the positive aspects and characteristics of various devices, selects the best air pump for the aquarium, suitable for the parameters for your tank.

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.

How to install a water pump in the aquarium

Install the pump in the aquarium can be easily subject to the instructions. The mechanism must be put on the shelf near the tank. In case of its absence, attach the device directly to the wall of the aquarium using suction cups. The mechanism should be installed in such a way that the sprayer and non-return valve could touch the bottom of the container or be closer to it.

Some aerators operate on alkaline batteries, but the bulk is powered by a current source, so the device needs to be installed closer to the outlet.

The sprayer must be attached to the wall of the aquarium or to its bottom. This is done with the help of suckers. After that, attach the tube to the sprayer and water pump.

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.

Adjustable

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. This increases or decreases the intensity of aeration. An adjustable air pump can have different types of regulation:

  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.

disadvantages

The main disadvantage of water pumps is noise. Many tank owners install an aquarium pump in soundproof boxes. This partially helps to solve the problem. Some manufacturers make models that are installed directly in the tank. During the day, their work is almost inaudible.

Alternative

Noise during the operation of the aerator brings inconvenience. There is its alternative replacement – the oxidizer. This is a homemade filter aerator for aquarium. With its help, oxygen is supplied to the tank through a chemical reaction. The basis is the decomposition of hydrogen peroxide into oxygen. A catalyst is required for continuous work.

Unregulated

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.

Tips

For the smooth operation of the device care is needed.

  1. It is required to change air filters and rubber membranes in time.
  2. Prolonged use results in contaminated filter.
  3. Holes are clogged and oxygen is poorly supplied to the aquarium. It is necessary to periodically clean.
  4. Sometimes hoses become useless, as crustaceans can damage their claws.
  5. It is necessary to have one more device, in case of breakage of the main aerator.

Piston

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.

The main advantages of a piston pump:

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

Membrane

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.

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.

  • the hose is short.

Dimensions

The water pump is chosen according to the size of the aquarium itself. If it is large, then there will be no particular problem in this matter. What to do if the aquarium is a very small volume? It is necessary to select compact aquariums. In most cases they have not very high performance and power. In addition, almost all compact models are unable to regulate the air flow, but for small aquariums this is not particularly necessary.
