The EHEIM reeflexUV clarifiers use UV-C radiation to clean aquarium water in fresh and sea water aquariums and are operated in the filter system’s water cycle (discharge side) or by using a separate circulation pump (not included).
Aquarium water permanently flows through a glass tube and past the UV-C bulb inside the aluminium body. As a result, free-floating algae, bacteria, fungi, viruses and other pathogens are reduced or eliminated. The EHEIM reeflexUV clarifiers
ensure that aquarium water is clean and crystal-clear, keeping the fish healthy.
