Ultraviolet (UV) lights are used in aquariums for several reasons, including:
Eliminating Harmful Organisms: UV lights can help to eliminate harmful organisms such as bacteria, viruses, and parasites that can be present in aquarium water. The UV radiation destroys their DNA, preventing them from reproducing and causing harm to fish and other aquatic animals.
Improving Water Clarity: UV lights can help to improve water clarity by reducing the number of suspended particles in the water. These particles can make the water appear cloudy and can also provide a breeding ground for harmful organisms.
