Fish Tank Pump

Choosing A Quiet Silent Water Pump For Your Aquarium

August 8, 2019

Without aeration, many types of aquarium fish will not survive. The only exception is fish that can breathe air from the surface. The main drawback of the work of aerating devices is the noise produced. Experienced aquarists have come up with many ways to reduce the level of buzz during operation of the device. Many immediately buy a silent air pump for the aquarium.

How to use

In the operation of aerators often begin disputes. Some do not turn off the water pump, others turn it on only after the feeding process. But it will be more comfortable for the fish to switch on and off alternately at regular time intervals: work 2/2 hours (that is, 2 hours air enters and 2 hours the machine is turned off) or 3/3 hours. But too long breaks should not be done, because the oxygen in the water decreases. Turn on the aerator after feeding – fish need a lot of oxygen to digest food.

Types of water pumps

All quiet water pumps for the aquarium are divided into 2 types by internal mechanisms: diaphragm and piston.

Membrane views release air through several internal moving membranes. The air goes in one direction and does not suck water inside the device. Diaphragm water pumps differ in low energy consumption and work almost silently, not counting the splash of water. But this species is suitable only for small tanks with a small population of fish, the volume of which does not exceed 150 liters. Prized as an inexpensive but durable aerator.

Water piston pumps operate at the expense of an internal piston that pushes air flows through the tube. This species is not so quiet and produces a slight buzz, which is not too noticeable. They have a higher price, but they are capable of enriching much larger volumes of oxygen with oxygen. Piston devices with a low price often do not have good quality. They are pretty hot, which is bad for fish.

There are devices on sale that do not release air bubbles from an underwater tube, but are on the surface. They create ripples on the water and the constant movement of water, during which the water enriches with oxygen. But this species is not suitable for keeping bottom fish.

Aerating devices are powered from the mains, but there are also batteries. Battery aerators are used for transporting fish.

An alternative to a silent aerator for the aquarium are oxidizers. These devices are completely silent, because the process of enriching water with oxygen is due to chemical reactions. The device is hydrogen peroxide, which decomposes into water and oxygen due to the effects of catalysts – metals.

Still aquarists use aquarium pumps. This collar apump unit combines the functions of an aerator and filter – it enriches the air with oxygen and purifies water. It is equipped most often in large-scale aquariums. The aquarium pump produces little noise due to complete immersion in water.

For a small volume

Aquael OxyBoost 300, Aquael, Triton, Sicce and DoPhin AP 1301 are considered suitable for tanks of small volumes.

Aquael OxyBoost 300 is a fairly inexpensive and practical aerator. There are rubber mounts that reduce noise and vibration. The power consumption is 2.5 W, and the amount of distilled water is 100 liters per hour. Differs in small size. The disadvantage is that the rubber feet do not always reduce the noise.

The DoPhin AP 1301 is a miniature machine that produces up to 95 liters per hour and spends 1.7 watts of power. The maximum aquarium size for aeration is 125 liters. The noise level is low. The kit does not include additional equipment. If necessary, you will have to buy it yourself.

Sicce is a low power aquarium equipment, therefore it is well suited for small tanks. When mounted in a vertical position, the vibrations are minimal due to the special legs. It is possible to adjust the performance. Suitable for aquariums up to 100 liters.

Triton is a micro-air pump manufactured by a Chinese company. Power 3 W and suitable for tanks up to 150 liters.

Aquael is produced by a Polish company. Create a minimal amount of noise and are unaccustomed

ny appearance.

For high volume

For large tanks, Schego Optimal and COLLAR are suitable.

Schego Optimal is designed for tanks up to 300 liters and is capable of pumping 250 liters per hour. Spends 5 W of energy. Vibrations are weak, so they almost do not create noise. With the help of a tube splitter from the apparatus can be carried out to several aquariums. The aquarist chooses the position himself: the water pump can be suspended in the air or attached on legs. In the aerator quality membrane, there is a pre-filter; all this protects the device from pollution and damage. Long service life.

COLLAR is suitable for tanks of 200 liters and is suitable for large aquariums, even though it differs by its small size. The height of the tube is 80 cm, and the power device 3 watts. The model has a long service life and high-quality parts. Suitable for any aquarium.

High power

Powerful devices provide sufficient oxygen daily. This is especially important in densely populated tanks. The most common brands are Eheim, JBL ProSilent.

Eheim is produced by a German company and is recognized for its quality. For an hour the device pumps over 400 liters of water. The device is suitable for any aquarium. Included are another spray and a long hose. Power consumption 5 watts. The aerator is quiet and almost invisible. The owner of the underwater inhabitants is able to adjust the spraying power and flow he needs. The disadvantage is the high cost.

Portable devices are necessary during periods of transporting fish or when a power outage. These water pumps do not operate from the electrical grid, like most devices, but from batteries located inside. The most common device is a water pump under the brand name Hagen Marina. The device pumps 50 liters per hour and has a low price.

Install the silent water pump correctly

Before installation, locate the location for the water pump and read the instructions. Some models are located right in the water, others above the surface. External aerators attach on the table, the lid of the aquarium or special places – shelves. Place at such a distance that the length of the underwater tube is enough to the bottom of the aquarium. The lower the spraying location, the better the water will be enriched with oxygen.

Copies with suction cups are attached directly to the walls of the aquarium, and the outer tube is on the surface.

It is better to place the underwater tube next to the heater. Air bubbles will immediately mix layers with different temperatures, which will favorably affect the fish, because the same temperature throughout the entire volume of the aquarium is more useful for them.

Remote water pumps were the solution to the noise problem for some. The device itself with a long tube is placed away from the aquarium, sometimes even in another room. This provides complete silence if other methods of reducing noise do not help.

Silent water pump do it yourself

It is important to understand the principle of operation of the device before work. In the process, the aerator must first accumulate air, and then release it under pressure through a tube in the aquarium. The most common places for air accumulation are cameras of balls, cars, and balloons. Usually, these are rubber objects, which are distinguished by a small stretch. In addition to the rubber chamber, you will need a small hand pump from a car or bicycle.

To connect you will need to purchase a three-way valve. These faucets vary in size. We need a small faucet, used for heating systems, and miniature products, for example, for medical purposes. You also need a tube from the dropper, at the end of which there must be a clamp.

How to make a silent air pump for an aquarium with your own hands:

  • Attach 3 thin tubes to the pump, the rubber chamber, and the third will supply air. Connect everything and ensure tightness.
  • Seal the free end and make several small holes in the tube.
  • Inflate the rubber chamber with a hand pump, then close this path.
  • Open the passage from the camera to the free tube.
  • Adjust the tube diameter with a clamp.
  • Experiment with the amount and speed of air supply suitable for fish.

Primitive water pump is ready. But consider the need to constantly pump up the chamber to the pumps so that the air does not run out. This should be done 2 times a day approximately every 12 hours, therefore, it is impossible to leave a self-manual device for a long time.

The best model of the water pump in quality and price

Tetra APS became the leader among other silent aerators. The water pump has enough power to work in both small and large aquariums from 5 to 100 liters. They note its high performance, because in 1 hour Tetra APS pumps up to 100 liters. Low power consumption – only 2.5 watts.

Noiselessness is achieved by rubberized legs and mounts, which suppress any vibration and noise. An even greater amount of noise emitted is reduced due to the structure of the device.

The aquarist is able to independently regulate the amount of incoming air.

The low price further increases the popularity of the water pump. Tetra APS can be purchased for about 1000–1500 rubles.

Noise reduction features

Even initially silent water pumps after a while can begin to emit audible buzz and noise. This especially interferes with finding an aquarium in living rooms, bedrooms or large aquariums, which require powerful devices. You can reduce the noise level at home.

If the source of noise is the buzzing of the aerator on glass objects, then the solution to the problem will be placing a soft kitchen sponge under the water pump. The sponge will absorb noises and buzz.

Even for a water pump, boxes for partial insulation of wood or plastic are carried out, and inside, boxes are pasted over with foam rubber.

If this does not get rid of the noise, then open the device without damaging the parts. Usually, the noise comes from the work of the membrane, which presses on the air. Carefully cut or saw off the interfering parts of the membrane and the sounds of noise will disappear.

Choosing A Quiet Silent Water Pump For Your Aquarium

The cause of unnecessary sounds and poor performance of the aerating device is often contamination of internal parts. To prevent contamination, clean the aquarium every month. There are still noisy details. To stop the noise, simply twist the loose parts.


Silent aquarium inlet pump is considered a simple device, but without it, the contents of the aquarium is unthinkable. This device must be purchased before buying fish. Pay much attention to the quality of the device. It is also necessary to take into account the power, the volume of the aquarium and the number of underwater inhabitants. Therefore, the water pump provides invaluable assistance to support comfortable conditions for fish life.
