Description

Closed fish tank filter cartridge

technical field

The invention relates to the field of aquarium breeding, in particular to a closed fish tank filter cartridge.

Background technique

The pet fish and aquatic plants raised in the aquarium are always metabolizing, and the harmful substances in the water quality are increasing at any time, so the water quality in the aquarium is an uncertain and dynamic environment. However, pet fish and aquatic plants can grow normally only in a suitable living environment. To maintain the stability of water quality, it depends on the filtration system.

The filter system is an important part of the aquarium. Its function is to filter impurities in the water, fish excrement, fish secretions, residual bait, rotten branches and leaves of aquatic plants and water through the filter material in the filter. The organic matter in the aquarium is filtered out, so as to adjust the various indicators of the water, keep the water quality in the aquarium fresh and thorough, and maintain the water quality in the aquarium stable.

According to the working principle, the filtration system is generally divided into three types: physical filtration, chemical filtration, and biological filtration. Physical filtration uses the fibers in the filter cotton to block insoluble impurities and waste in water. Chemical filtration removes soluble impurities in water through chemical methods. Harmful substances or adjust the PH value, biological filtration uses the biological action of nitrifying bacteria to convert the toxic waste produced by the metabolism of fish and aquatic plants into non-toxic substances.

The existing fish tank filtering device has a single function and cannot comprehensively filter and purify the water quality. In order to ensure the stability of the water quality, the water must be changed frequently.
