More widespread vibratory vodushnye pumps. The low cost allowed them to take a strong position in the niche of the hobby class, and the well-thought-out design provides high-quality water saturation with oxygen. But it should be understood – such devices function due to vibration, which always acts as a source of noise. There is no completely silent membrane devices. At best, the manufacturer may try to lower the volume level as much as possible, but such tricks automatically lead to price increases.
If you don’t want to overpay for a “quiet” vibrating water pump, you should try to solve the problem yourself. For example, you can put a piece of foam under the device, or you can put an aerator in another room where no one is resting.
Piston models are more often purchased by people who are seriously involved in aquarism and can allocate a significant amount to acquire a powerful device. Such devices are classified as professional and able to cope with any home aquarium.
Which aquarium inlet pump to choose the type of power?
Most often, air pumps (both piston and diaphragm) are powered from the network – this is a classic option. But what to do if the electricity often disappears for a long time? Or do you need to carry fish over a considerable distance?
Like almost any other device, the air pump for the aquarium has a mobile version designed to operate in the absence of electricity. Such a device works on batteries and can be both vibration and piston. The device has a relatively high cost and significant noise while maintaining low power.
Mobile vodushnye pumps on batteries – a good compact option for cases when you can not get to the network. For example, while trading fish at a non-electrified point. The use of such aerators at home is impractical: they "eat" a lot of energy, with the result that the battery pack lasts about 4-6 hours.
If there is no urgent need to disconnect the water pump from electricity, it is better to buy a network model.
How to choose an air pump for the aquarium on the main parameters
Acquisition of a water pump requires careful study of the presented model range. Special attention should be paid to such characteristics:
- Performance. The main parameter describing the amount of air that a water pump is capable of overtaking for a certain time period. There are different opinions about the optimal value, first of all it depends on the type of fish bred and the density of the population of the aquarium. Traditionally, the minimum capacity is 0.5-0.8 l / h per liter of “can” volume. For example, for a 100-liter aquarium you will need an aerator for 50-80 l / h, for a 300-liter – for 150-240 l / h. But the presence of a biofilter in the "bank" increases the minimum requirements by 1.5-2 times.
- Noise level. It should be understood that this characteristic depends not only on the type of construction, but also on the manufacturer. Moreover, tempting descriptions (for example, “completely silent water pump”) do not guarantee that the device will actually work quietly. It is advisable to check the device yourself, preferably in a quiet room. It is necessary to take into account your own preferences: what seems too loud to one does not bother the other person at all.
- Power. It determines the degree of energy consumption and affects the performance, as well as the maximum possible depth of immersion of the sprayer. Mostly on the market are models for 2-11 watts. The deeper the sprayer, the more powerful the device should be purchased.
- The number of channels. The presence of two or more channels makes it possible to connect the water pump to several aquariums at once.
- The volume of the aquarium. Manufacturers, as a rule, designate the “banks” of what size is the water pump designed for. It is worth listening to this recommendation.
how to install, what for, how to choose
Water pumps for an aquarium are one of the important attributes that ensures the flow of air into the tank. Often, an artificial pool is filled with many inhabitants who do not always have enough oxygen. Plants are not able to provide representatives of the right amount of air, so you need to install a special pump in the aquarium.
Why do you need
Inexperienced owners are confident that the amount of oxygen emitted by plants is sufficient for a comfortable life of inhabitants. Algae form o2, but in a small amount, which is not enough for containers with large volume.
The formation of aquatic ecosystems is adversely affected by:
- fish excrement;
- rotted feed particles at the bottom;
- lack of oxygen adversely affects the formation of the aquatic ecosystem.
Exotic species of fish are fastidious to the conditions of detention, so the lack of sufficient air can lead to their diseases or even death. And also standing water is exposed to the formation of a film on its surface. The air flows supplied by the pump enrich the reservoir with oxygen, which is necessary for the healthy development of the inhabitants. This process is called aeration (air supply to the aquarium). All water layers are mixed together, so that the reservoir will not look like a swamp.
How does it work
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.
There are special water pumps that simultaneously have a filter – pump for the aquarium. We talk more about them in another article.
Regulated and unregulated
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. If necessary, it is repaired. Among the shortcomings of a piston water pump, there is a high power consumption and an overestimated price.
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. Differs in low cost. Among the disadvantages can be identified high noise and low power. Installing it in aquariums with a volume of more than two hundred liters does not make sense.
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.
Required performance depending on the volume of the aquarium
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.
For small aquariums, up to one hundred liters in volume, an aerator with a capacity of up to 80 l / h is suitable. More capacious tanks will require a device with a capacity value up to 240 l / h.
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.
How much should work
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.
How to choose the top 3
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:
- Schego water pumps.
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 devices are equipped with special legs that provide stability. If necessary, they can be hung to the wall. The devices of this manufacturer have a number of positive aspects:
- 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.
How to install
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.
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.
At installation of the aeration device it is necessary to be careful, as the main mass works from electricity. Non-compliance with safety measures is fraught with closure, which will lead to the death of the inhabitants of the reservoir.
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. His role is played by metals. As a result of the reaction, the catalyst is oxidized and releases oxygen into water. The device is used without electricity. During the work does not make noise.
For the smooth operation of the device care is needed.
- It is required to change air filters and rubber membranes in time.
- Prolonged use results in contaminated filter.
- Holes are clogged and oxygen is poorly supplied to the aquarium. It is necessary to periodically clean.
- Sometimes hoses become useless, as crustaceans can damage their claws.
- It is necessary to have one more device, in case of breakage of the main aerator.
