Recommended aquarium volume
The volume of the aquarium in liters in which the filter will ensure proper water purification performance. This parameter is usually indicated approximately, because when choosing an aquarium filter, it is important to take into account other factors: the degree of population of the monastery for underwater inhabitants, the size of the fish, etc.
Filter
-
Mechanical. Filters for purifying aquarium water from solid suspensions: food debris, fish waste products, debris, sand and other small particles. The mechanical type of filtration keeps the water clean and clear, improving the visual appearance of the aquarium and reducing the concentration of solid particles in it. As a rule, such filtration is carried out by sponges with different pore sizes.
—
Multi-level. Models that have several levels of filtration at once. Most often, multi-level filters perform mechanical and biological water purification (removing solid particles from it, as well as decomposition products of organic substances). Advanced aquarium filters also provide chemical filtration - water purification using chemicals and adsorbents (for example, activated carbon).
— Filter volume. The volume of the internal filter container in which filter materials and water purification mechanisms are placed. The parameter is measured in liters and indicates how much water the filter can hold during operation. The larger the volume, the better the filtration efficiency, so you can extend the interval between cleaning the aquarium.
— Number of baskets. The number of baskets containing different filter materials. It can vary from one to three, less often - up to four or five. A large number of baskets are provided in complex filtration systems, which often include additional s
...tages of water treatment: ultraviolet treatment, water heating, etc.Power
The power level, measured in watts, determines the energy consumption of the filter and/or its components (compressor, fan, etc.). This parameter indicates how much electricity the filter “winds” during operation and is not directly related to its filtration performance (see below).
Performance
The volume of water that the filter is able to process and purify per unit of time. Often this parameter is measured in liters of water per hour. Filter performance is directly related to the recommended aquarium size. It is customary to ensure that the flow rate of liquid passing through the filter in one hour exceeds the volume of the reservoir at least three times. Thus, for a conventional aquarium with a volume of 200 l, the recommended filtration capacity should be at least 600 l/h.
Water flow adjustment
The ability to choose the optimal direction of water flow at the filter drain relative to the water surface. Adjusting the flow angle ensures an even distribution of oxygen and nutrients, and also creates a suitable water flow, simulating conditions in the natural habitat of fish. At the same time, by
correcting the direction of the water, it is possible to prevent the accumulation of debris and deposits of contaminants in certain areas of the aquarium.
Country of brand origin
Country of origin of the brand under which the products are presented on the market. Often indicated by the nationality of the company or the location of its headquarters. However, the actual production capacity of a brand often differs from its country of origin.
Let us note that the quality of products depends not so much on geography, but on the specific organization of processes and quality control at all stages of production. Therefore, national prejudices regarding brands from certain regions, as a rule, are not supported by anything. It is necessary to pay attention to the country of origin of a brand only if the goal is to fundamentally support or bypass a manufacturer from a specific country.
