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.
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.
Power adjustment
Possibility of adjusting the flow of water passing through the filter. In practice, this is often achieved by rotating a special valve or diffuser at the inlet or outlet of the filter.
Adjusting the power can be useful to tailor the filter to the specific needs of the aquarium and underwater inhabitants.
Water flow adjustment
The ability to select the optimal direction of water flow at the filter's outflow relative to the water surface. Adjusting the flow angle ensures even distribution of oxygen and nutrients, while also creating a suitable water current that mimics the natural habitat conditions for fish. Additionally, by
adjusting the water flow direction, it's possible to prevent debris buildup and the accumulation of waste in specific 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.
