The top filtration aquarium is an aquarium design where the filtration system is located at the top of the aquarium. This design can provide effective water quality filtration and gas exchange, while not occupying the internal space of the aquarium. Here are some key information about the top filtration aquarium:

Filtering principle: The top filtration system usually includes mechanical filtration, biological filtration, and gas exchange functions. Water is extracted into the top filter, and the mechanical filter layer is used to capture and remove impurities, waste, and solid particles. The biofilter layer provides biofilters in which beneficial bacteria grow, decompose, and remove harmful substances such as ammonia and nitrates. In addition, top filters typically increase gas exchange through air pumps or surface surge devices to ensure sufficient oxygen is obtained in the water.

Installation method: The filtration system of the top filtration aquarium is located inside the top cover of the aquarium, usually with a transparent top cover or baffle for observation and maintenance. The filter material and pump are usually located below the top cover.

Applicability: Top filtered aquariums are suitable for small and medium-sized aquariums, as well as situations where maximum utilization of internal space is required. They can be used in freshwater and seawater aquariums, for raising fish, insects, and other aquatic organisms.

Maintenance: Regular maintenance is the key to ensuring the normal operation of the top filtration system. Maintenance includes cleaning the mechanical filter layer, regularly replacing the filter medium, and inspecting and maintaining the air pump or surface surge device.

Flow rate and size: Choosing the top filtration aquarium that suits your aquarium requires consideration of the volume of the aquarium and the required water flow rate. Different models of filters have different flow rates and capacities.

Additional features: Some top filtration systems may have additional features such as adjustable water flow rate, heater slot position, UV sterilizer, or automatic level control.

Top filtration aquariums are a common solution for aquarium filtration, providing effective filtration and gas exchange, helping to maintain water quality and ecological balance within the aquarium. When selecting a filtration system that is suitable for your aquarium, please consider the size of the aquarium, the type of organism being raised, and the required filtration effect to ensure that it meets your needs.
