With UV-C water clarifiers, also called UV sterilisers, you can effectively clean aquarium water without adding chemicals. The UV radiation generated in the unit kills algae spores, pathogens, germs, bacteria, etc. The result is healthy, clean and clear aquarium water. Useful bacteria that settle in the filter material or substrate are not detected by the radiation. The Aqua Medic UV clarifiers are equipped with many useful details, such as the 360° rotatable water inlet, the water flow spirals for long water contact with the UV-C radiation or the sight window for function control. The devices are available in different performance classes for small and large aquariums in fresh and salt water.
