How does an aquarium filter work?

maintenance, care, compatibility

This article is aimed at newbies – aquarists. Many of them make a mistake: periodically turn off the aquarium filter for a short time. However, this is not recommended.

Moreover, the shutdown adversely affects the purity of the water and is meaningless. To verify this, consider the filter device.

This is a device whose components are a cartridge with filtering material and a turbine head. In turn, the filters are divided into internal and external.

Internal – these are those that are attached to the walls of the aquarium from the inside. Remote, or popularly called “buckets”, installed next to the aquarium, connected to it with a hose.

External filters have a larger volume than internal ones.

Most beginners face the same problem: the aquarium filter does not work, let’s try to understand how the filtering process takes place. It would seem that the system is quite simple.

The material in the filter accumulates dirt and when it becomes too dirty it must be washed with warm water and put back into place.

If you do not forget to do it all the time, the water in the aquarium will maintain its purity and transparency. But It is worth noting that with this use of the filter there will be white cloudiness.

And the more often you clean the filter, the more it will be.

If you look deep into the process, you can learn that it consists of two phases: biological and mechanical. Considering these phases, you can understand how the filter for the aquarium works.

The dirt retention on the filter material is attributed to the mechanical phase. After some time, the bacteria saprophytes decompose this dirt to simple mineral substances such as water, carbon dioxide, nitrates and others.

This phase is called biological. And if its implementation proceeds without any external intervention, the water in the aquarium will always be transparent.

We can say that the filter for the aquarium is a big mechanism, filled with a huge number of microorganisms. And if you constantly wash the cleaning device, it will be impossible to save the life of these microorganisms.

Therefore, the biological phase will not be fully implemented. This will lead to the fact that the water in the aquarium is filled with semi-decomposed substances, and microorganisms will accumulate in it that make it white and turbid.

The bacteria do not linger in the filter, and it is meaningless to hope to filter them out.

What to do with it? The answer is nothing.

Over time, a sufficient number of bacteria will accumulate in the cleaning device, and the unpleasant dregs themselves will gradually begin to disappear.

So, in the specialized shop with the help of a consultant, the necessary internal water purifier was selected. Before this, you should carefully check its completeness and read the tips on installing and running into work.

First, the device must be assembled according to the recommendations set forth in the instructions for use. Can’t wait to check it at work?

You should not hurry, because the filter must first be properly fixed in an aquarium filled with water. And, beginners, as a rule, have some questions.

How deep should the glass be dipped? What is plastic flexible transparent tube for?

The vast majority of internal water purifiers are attached to the wall of the aquarium in a vacuum way using special suction cups. These suction cups are included in the package.

Prerequisite: the filter must be completely submerged in water, the height of the water level above the top of the device must be from 2 to 5 cm.

A transparent flexible tube serves to supply air to the device and is attached to its “nose”. The other end of the tube should be outside the aquarium, outdoors.

It would seem that you can already run the “glass” in the work. However, experts recommend making the first inclusion, removing all living creatures from the aquarium.

You never know what! What if the device has a manufacturing defect? It is better not to risk and move all the fish for a short time in a small sump.

If the first inclusion showed the normal operation of the technical device, pets can immediately run into their water house.

After the first power up, it is recommended to set the power regulator, which is available on each filter, to the middle position. It takes some time to observe the condition of your pets and then empirically determine the optimum power of the filtering device.

Already from the name of this cleaner it is clear that it is installed on the bottom of a water house for fish. But the choice of this type of filter is resorted to only when there is very little or no decorative bottom aquatic vegetation in the aquarium.

Such a device is a relatively thin plate with an internal filter material and a multitude of holes through which water flows. Some believe that such a plate with tubes attached to it can be simply put on the ground and that will be enough.

This is a misconception – the bottom cleaner should be installed, not just put.

First, remove the soil from the bottom of the aquarium (or from a separate section) and put a plastic frame that will raise the false-bottom by 2-3 mm. Only then can the technical device be closed with a primer, and then put it into operation.

Not only the purity and high-quality chemical and biological composition of water, but also the degree of air saturation depend on the proper installation of any aquarium filter. In addition, it determines the reliability of the device itself.

In any case: before the water purifier is put into operation, you need to carefully read the instructions attached to it and strictly follow the rules specified in it.

How to install the internal filter in the aquarium, see the video:

Bottom filter for aquarium – an overview description of the photo video.

The principle of operation is very simple:

  • the pump drains the water out from under the grate,
  • then it is cleaned through a special filter element and returned to the aquarium;
  • then the water re-seeps through the ground, undergoing a rough cleaning, and the process begins anew.

In the tubes, which are located at the very bottom (under the plate), there are small holes through which water is drawn. Optionally, you can optionally install a tube with an aerator.

Thus, not only the filtration, but also the aeration of the whole soil will be carried out.
