How to install a filter in an aquarium: we work with external and internal cleaning systems

How to properly install a filter in an aquarium? It depends on its type. Even a novice fish lover can handle any variety. We arm ourselves with detailed instructions and set up a home for silent but beloved pets.

The need for a filter element

Filters are responsible for mechanical, biological and chemical cleaning of the aquarium. Some systems also saturate the water with oxygen, but experts recommend purchasing separate devices for aeration. Having a filter is a must. The system improves the microclimate of the aquarium and prolongs the life of the fish, especially the fastidious varieties.

Which to choose

There are two main types of aquarium filters: external and internal. Factors such as the size of the aquarium, the number of underwater plants and fish, and your budget will help you determine which one is right for you.

Internal filter

An internal filter is the simplest design, suitable for primitive small-volume aquariums. Operating principle: water enters the lower section of the apparatus and exits through the upper, simultaneously being saturated with oxygen. This device is attractive due to its affordable price, simple installation and low power consumption.

Among the disadvantages of the internal filter, we note that it takes up space inside the aquarium. Filtration and aeration are carried out by such a system to a sufficient extent only in small tanks.

Another unobvious disadvantage is associated with the need to frequently remove the filter. In order to take it out, you have to put your hands in the water. This can lead to infection entering the water and infecting its inhabitants.

External filter systems

An external filter is chosen by professional aquarists: such a system is capable of purifying large volumes of water from 100 liters. Fillers in this system are combined: these are stones, rings, sponges with biological material. Through a tube, water from the aquarium enters the apparatus, is purified and returned through another tube.

The filter is placed on the side of the glass, does not take up space in the tank, and works not only more efficiently, but also much quieter than internal structures.

Many people are stopped by the cumbersome nature of the external system. Not everyone can afford such a device, but the purchase is always worth the money spent. Cleaning of the structure is required infrequently; filter elements can be easily replaced with new ones.

Manufacturers

Give preference to trusted manufacturers. High-quality materials will prevent water damage and the death of fish, breakdowns will rarely occur, and spare parts will be easy to obtain if necessary. Among the popular filters in pet stores:

Aquael: a series of designs for internal installations for water purification in aquariums from 3 to 250 liters. Easy to install and operate, recommended for beginning fish breeders.
Barbus: internal cleaning systems of domestic production. Barbus filters are inexpensive, which is what attracts many buyers.
Fluval from a German company Hagen: An expensive external system with low power consumption and silent operation.
Firm Eheim offers both internal and external complex cleaning devices for aquariums, trusted all over the world.

Installation Instructions

You can install the filter correctly even without certain skills. Just follow the instructions that apply to each system.

Rules for internal filter:

The aquarium must be at least half filled with water at the time of installation.
The filter parts are assembled in a dry state. The device is connected only after complete installation.
The internal system is attached to the wall using suction cups or hooks. They should come together.
The depth of the filter is slightly closer to the surface. The recommended water level above the system is about 2-3 cm. In this case, the filter should not touch the bottom.
A tube for air suction is attached to the filter. it is directed upward and additionally secured to the glass.
The installed filter can be connected to the network. Try to make sure that the wire does not stretch, but hangs freely down from the outlet. If there is a noticeable current in the water, then the installation was carried out correctly.
Use a special regulator to control the water flow. It's better to put it in the middle position. Watch the fish, are they comfortable? If necessary, reduce the flow rate. Move the regulator after unplugging the device from the outlet.

The magazine purity-en.htgetrid.com advises removing a non-functioning filter from the tank to avoid poisoning the fish.

How to position an external aquarium filter, stages of work:

Unpack and assemble the filter parts in the order described in the instructions.
The external filter should be placed 20 cm below the water level in the tank.
Place the water intake tube (it has a curve) into the aquarium.
Install the outlet tube on the opposite side.
Before connecting, the device must be filled with aquarium water using gravity. If this is not done, the air in the tubes will interfere with the normal operation of the filter. Procedure: First open the tap to fill the water intake tube. Wait until the filter is full. Next, close the inlet hose and open the valve for the outlet pipe.
Now you can connect the external filter to the network and open both taps.
Read the instructions carefully, as different manufacturers may have nuances related to both the use and installation of the device.

Advice
If the external filter has a strong power, you need to put a mesh on the end of the tube so that the system does not suck in small fish.

If water does not flow well into the external filter, then you need to clean the air pockets in the pipes. Simply turn the device on and off several times. If this does not help, drain all the water and refill the device.

Choose a filter system in accordance with the needs of the aquarium and do not be afraid of modern designs: the instructions will always help you understand the installation. Also, do not forget to regularly clean the filters to remove any remaining dirt and organic matter. The purity of the water and the comfort of the fish in it are worth this little effort.
