Contemplation of aquarium fish has a relaxing effect on the nervous system. These silent inhabitants of an artificial reservoir do not create much trouble for their owner, but this does not mean that care is not required for them and their habitat. In order to create optimal conditions for the existence of fish and other microorganisms, mechanical, chemical and biological water treatment is important. A good aquarium filter will help in this matter. How to choose the best from the available variety of popular models is discussed in this article.
A distinctive feature of the device is a spherical head, which ensures the movement of water flow in various directions. The built-in diffuser ensures the enrichment of the liquid in the aquarium with oxygen. Through the power regulator, you can change the water flow. The mechanical-biological purification of the liquid medium of the aquarium is carried out by means of sponge cartridges in the filter housing. The filter cloth in the filter box enhances the mechanical cleaning effect.
The design provides for such a connection of compartments (modules), which makes it possible to wash them locally. This is important in terms of preserving beneficial bacteria. In addition, a blockage in one of the compartments will not affect the operation of the filter as a whole. There is a special compartment for the filter substrate.

The kit comes with Bio Rio M fillers that stimulate the dissolution of oxygen in the aquarium water: this increases the activity of beneficial bacteria and, as a result, the efficiency of the biological filtration process.
The pump is attached to the body of the device: this eliminates the effect of electromagnetic waves on bacterial colonies in the device, which contributes to their comfortable development.
The filter implements the main cleaning methods:
The first allows you to remove large particles from the liquid medium (fragments of algae, food residues and life of aquatic inhabitants). The second - removes pollution due to the adsorption capacity of activated carbon. Carbon is often used at the initial stage of starting an aquarium to purify the water and prevent water staining and ammonia poisoning of the inhabitants of an artificial reservoir. Due to the fact that the adsorption capacity of activated carbon is limited, for its effective use it is necessary to change the carbon twice a month.
The third cleaning method is given a key position.Settlements of microorganisms in the filter are involved in the process of assimilation and decomposition of organic matter, plankton, microbes in the water: nitrifying bacteria convert ammonium, which is contained in fish excrement, into nitrite, and then into nitrate.
The average cost of the device: 75,000 rubles.
