The external ultraviolet filter of an aquarium is a device used to improve the water quality of the aquarium. It uses ultraviolet light (UV-C light) to kill bacteria, viruses, algae, and other microorganisms in the water. Here are some key information about the external UV filters of the aquarium:

Working principle: The external ultraviolet filter extracts water from the aquarium into a special compartment, which contains ultraviolet light tubes. These ultraviolet tubes generate ultraviolet radiation with high energy, which can kill microorganisms in water, including bacteria, viruses, and algae. By killing these microorganisms, ultraviolet filters help improve water quality and reduce the number of pathogens and algae in the aquarium.

Water quality improvement: The use of external ultraviolet filters can improve the water quality of aquariums, making the water clearer and reducing the number of pathogens in the water. This helps to prevent the spread of diseases and reduce algae outbreaks in aquariums.

Installation: The external ultraviolet filter usually needs to be installed outside the aquarium, and connected to the aquarium through a water pump and pipeline. Water is extracted from the aquarium into a filter, treated with ultraviolet light, and then returned to the aquarium. Installation of filters requires certain pipeline and water pump configurations, depending on the size and shape of the aquarium.

Maintenance: Regular maintenance of external UV filters is crucial, including regular cleaning of filters and replacement of UV tubes. These steps ensure the effectiveness of the filter to continue effectively killing microorganisms.

Applicability: External UV filters are usually suitable for large aquariums, such as ponds or large seawater aquariums. They can be used in freshwater and seawater environments.

Combination with other filtration devices: Typically, external ultraviolet filters are used in conjunction with other filtration devices such as mechanical and biological filters to achieve comprehensive water quality management.

External UV filters are a powerful tool that helps improve water quality in aquariums and prevent disease transmission. When selecting and installing external UV filters, make sure to consider the size, type, and specific needs of the aquarium in order to select the appropriate filter model.
