                                While salt is a necessary component for any saltwater aquarium, standard household salt is not a safe or effective substitute. The additives and lack of essential trace minerals in products like Morton salt make them unsuitable for the delicate ecosystems of marine tanks. Using household salt can introduce harmful substances and fail to provide the correct balance of elements needed for fish and coral health.
