二.  What is an aquarium UV light and how does it work?

First, let's talk about UV light. You might think that aquarium UV lamps emit the same UV rays that we block with sunglasses, but that's not the case.

Of the ultraviolet rays from the sun, only UVA and UVB penetrate the atmosphere to hit us, causing sunburn, spots, and even skin cancer. But this is not the same as the UV lamps used in aquariums. The UV lamps used in aquariums emit UVC, as does the sun, but UVC wavelengths are too short to penetrate the Earth's atmosphere.

Aquarium UV lamps do not kill microorganisms directly, but mutate them so that they cannot grow and reproduce. The main role is some bacteria, parasites, algae, and these are impossible for traditional filter cotton, filter media, etc. 

Fish excrement and other harmful substances are removed from the water through biochemical filtration, but there is no way to deal with some bacteria, parasites and some algae in the water, and the aquarium ultraviolet lamp effectively makes up for these.
