How to choose a water pump for a home aquarium

Deciding to decorate your home with a small part of the underwater world, aquarium amateur should take into account a large number of factors that will later affect the health of the fish and the appearance of the aquarium. In addition to the corresponding aquarium, the inhabitants of the underwater world also need a sufficient amount of oxygen, because its concentration in real water is constantly changing and air dissolved in water is lost. This problem solves the air pump for the aquarium. This device performs aeration – the saturation of water contained in the air.

The water pump facilitates the circulation of water in the aquarium, making the temperature in the water column uniform. Air bubbles coming out of the water pump and rising to the surface destroy the film of bacteria and dust, which significantly improves aeration. In addition, the fountain of small bubbles, located in a suitable place, perfectly performs a decorative function and pleases the eye.

Types of water pumps

According to the principle of operation, water pumps are divided into diaphragm and piston, and each should be considered separately.

  • In a diaphragm or vibratory water pump, air is injected by moving special diaphragms that allow air to flow in one direction. It is great for small home aquariums due to its small capacity, compactness and quiet operation, as well as a relatively low price. If you want to install an aquarium in a bedroom or children’s room, where the noise level is especially important – a membrane water pump is right for you.
  • In reciprocating air pumps, air is supplied to the aquarium by means of a piston, which is driven by an electric motor. Such water pumps can be very powerful, however, their price is much higher than the cost of membrane water pumps, and the noise level of piston water pumps is much higher. Such water pumps are used in large aquariums and columns, as well as in artificial reservoirs where more power is needed and the amount of noise is not so important.

Water pumps can also vary in type of power, sharing on electric, working from a household electrical network, and autonomous (battery). The latter are necessary during the long transportation of fish, as well as during long-term outages. Battery water pumps can be both piston and vibration. During their use, you need to remember that the windings and the electromagnet of the engine require a large amount of energy. One set of batteries ensures continuous operation for four to six hours for most designs. However, there may be exceptions.

Which aquarium water pump to choose: criteria

Choosing a water pump for your aquarium should take into account the noise level produced by the device – this characteristic is better to check in advance in a quiet room. Also important is the power of the water pump, which is calculated in accordance with the volume of the aquarium using a specific formula: 0.8 l / h per 1 liter of water in the aquarium. How to choose an air pump for an aquarium of 200 liters in accordance with this formula? Very simple: 0.8 200 = 160 liters per hour – the recommended power for this aquarium. Experts note that in some cases, the figure should be reduced to 0.5 l / h, and in some to increase to 1 l / h.

Much depends on how the aquarium will be populated, because each type of fish feels comfortable as close as possible to the natural conditions. When choosing an aquarium, you should also pay attention to the regulation of the air flow, the ability to change the force, the flow rate of air from the air pump and the settings of the device, taking into account the type of filter and sprayer.

Installing a water pump aquarium.

To install a water pump, you must follow some rules. First of all, it should be noted the place where the water pump will be installed. The external aerator is located on a glass lid or on a shelf so that the end of the hose is located close to the bottom of the tank in order to provide aeration from the bottom to the surface of the aquarium. The aerator should be placed closer to the heater, so the water, when heated, will immediately be mixed, providing an optimal microclimate for the fish living in the aquarium. In case of excessive noise of a water pump, it can be installed on a soft surface, for example, on foam or foam rubber. This trick will help to reduce the amount of noise.

Use of water pump

There are many opinions on the subject of when to aerate water. Some aquarists leave the water pump on all the time, while others follow the schedule: two hours of work, two hours of break. It is also recommended to always turn on the water pump after feeding the fish. It should be remembered that the water pump of the aquarium needs regular cleaning. If you do not perform cleaning, then the water level of the pump will increase the noise level, or the device will fail at all.

How to choose an air pump for an aquarium?

Having decided to start a fish house, you will need to acquire not only a suitable aquarium, but also all the necessary equipment for it, which will help create a properly functioning system and provide the fish with comfortable living conditions. In decorative aquariums, additional aeration of water is often required. To ensure it, it is necessary to purchase a special aquarium inlet pump, thanks to which the inhabitants of the aquarium will not experience a lack of oxygen dissolved in water. By installing an air pump for the aquarium, you will provide a permanent aeration in your aquarium, which will occur through artificial air injection.

Installing a water pump provides comfortable living conditions for the inhabitants of the aquarium, and also gives the device a decorative effect due to air bubbles rising to the surface. In addition, the presence of a water pump in the aquarium contributes to the destruction of the bacterial film formed on the water surface and to equalize the temperature of the water in the aquarium throughout its volume.

Aquarium inlet pumps are external and internal. External water pumps are more decorative, they do not occupy space inside the aquarium, but are noisier than internal models. If you need a silent air pump for an aquarium, it is better to purchase an internal water pump (pump), whose quieter operation is ensured by the fact that the rotating element is constantly in the water. When choosing a water pump for an aquarium, one should proceed from the minimum required capacity – from 0.5 l / h per liter of water available in the aquarium. The greater the volume of the aquarium, the more powerful a water pump is required for it. Especially convenient vodushnye pumps with air supply adjustment function.

Aquarium inlet pumps are of two types: diaphragm and piston. In reciprocating pumps, the air is supplied to the aquarium with a piston. Water pumps of this type are characterized by long life and high power, but at the same time they are more expensive and have a higher noise level. Membrane water pumps air into the aquarium is served using a rubber membrane. As a rule, they have rather small power and reduced noise level. The choice of a suitable water pump depends on a number of factors – the volume of the aquarium, its location, etc. For example, if the aquarium is located in a sleeping room or in a children’s room, one of its most important characteristics is noiseless operation. For an aquarium installed, for example, in the corridor, the level of noise produced by the pump is not so important.

How to choose an air pump for the aquarium – tips for beginners

Therefore, to begin with, we will try to figure out why a water pump is generally needed. The obvious answer, which suggests itself, is to enrich the aquarium water with oxygen. However, this is not the last role of this device in the aquarium life. The device is necessary for mixing layers of aquarium water and create water convection. Based on the information received, you can ask the question: “So why then internal and external filters, because they have a similar function?”.

Of course, you are right, but the work of the water pump is quieter, this is especially true at night, or in rooms where utter silence is required. In addition, filters cannot supply small air bubbles through the socket, and this directly affects the solubility of oxygen in water. Just do not forget that not every aquarium can be inserted into the filter, for example, in a spawning or nano-aquarium. In such banks, using airlift pump, they make airlifts, which can easily replace filters.

In addition, the aquarium inlet pump is a very mobile device, unlike external and internal filters. That is, you can install it in any place you like, but you can even take it out of the room. Only the main thing to stretch the necessary air tubes to the bank The most optimal version of the water pump is a battery-powered device. Older aquarists remember even the Soviet adapters made of rubber pear, in the “ass” of which they make a hole for the discharge of air when transporting aquarium fish. Now this thing you will not find anywhere. Oh, and I almost forgot. Aquarium water pumps for sale are single-channel (with one choke for air supply), two-channel and multichannel. In addition, the devices are adjustable and not adjustable.

What is the salt? A special regulator is installed on the body of the device, thanks to which the aquarist can change the applied voltage, which allows smoothly adjusting the air supplied to the aquarium. In modern aquarism, there are several groups of water pumps:

  • stand-alone devices;
  • general consumption devices;
  • water pumping stations;
  • professional devices.

I would like to focus on two groups.

water pumping stations

Their main difference from other devices is high performance due to greater power consumption. Stations are installed, as a rule, if you need to blow huge volumes of water. They are piston and electromagnetic. Structurally, they are not so different. Inside the devices you can find vessels for the accumulation of air and receivers. Here I would also record professional water pumps in this subsection, which are also used when blowing large aquariums with a high water column. Their internal parts are made of high-quality materials, so such devices serve for a very long time.

Autonomous water pumps

These are devices of small size that work from alternative energy sources and are capable of supplying air to the aquarium, even if the electricity has been cut off. It happens that such devices are equipped with a complex of various devices that automatically recharge batteries and supply air when the main equipment is turned off. What to pay attention to a novice aquarist when choosing a water pump for the aquarium.

To begin with, you should know how much your aquarium has and what its net volume, taking into account the soil and decorative elements. You should also know how much water is needed for each adult fish that swims in your underwater garden. In addition, you should know the height of the water column. A small annotation is sent to all water pumps, on the basis of which you can make the right choice. There are now a huge number of manufacturers of aquarium equipment on the market, but the most reliable are atman, tetratec and aquael. Remember, you buy a water pump for at least 5 years, so you should not strive for cheapness, buy a normal unit better.

And at the end of today’s demagogy, I would like to send a word of thanks to clever men. It is not necessary to pave cotton wool under the membrane to reduce noise. This directly affects the amplitude of the oscillation of the membrane, which leads to disruption of its work and increased wear. In addition, do not wrap devices with different materials, which greatly reduce air circulation. This can cause overheating of the internal mechanisms of the device and its failure. And about the removal of the check valve, I generally keep quiet, it is generally the finish.

That’s basically all for today. Thank you for giving me some of your precious time.

How to choose an air pump for the aquarium

At first glance it may seem that the fish – the most unpretentious pets. But this is not quite true: such pets are very demanding to the living conditions. In particular, in order for the fish to feel comfortable, it is imperative to take care of the oxygenation of water. For this purpose, a water pump is installed in the aquarium. How to choose it?

Any aquarium inlet pump is an air pump designed for aeration. There are two main approaches to the implementation of this idea:

  1. Vibration (membrane) models. The device works due to oscillations of the magnet transmitted to the elastic membrane (as a rule, rubber is used as a material for it). Due to this, pressure drops inside the small chamber, tightly connected to the membrane. From this "compartment" the air moves in the direction of the aquarium.
  2. Piston models. At the heart of the design is an electric motor that drives a piston pump. Rotational movements of the motor shaft turn into oscillatory, thereby achieving the desired power to supply air.

The advantages and disadvantages of both types of devices are:
