Aquarium systems refer to the various components and equipment used to create and maintain a healthy environment for aquatic life. These systems typically include tanks, filtration units, heaters, and lighting, all designed to support fish, plants, and other organisms. Properly set up aquarium systems help regulate water quality, temperature, and light, which are essential for the well-being of the inhabitants. In addition to the physical components, aquarium systems often involve monitoring tools and maintenance routines. Regular testing of water parameters, such as pH and ammonia levels, is crucial for ensuring a stable habitat. Hobbyists may also use products like water conditioners and aquarium additives to enhance the ecosystem within their tanks.
