UVC-C Series aquarium uv sterilizer use high intensity ultraviolet light to kill free floating microbes – bacteria, fungi, viruses, parasites and algae (only free-floating; they won’t cure illnesses). UVC-C Series of sterilization of water lack risks associated with ozonizers, but aquarists are divided on whether to use them – a well maintained, appropriately stocked aquarium should be fine without one. But many do use them to improve water quality, and they clear up lots of persistent problems quite well. They are well used in water cooler, pool, tank etc…
Most uvc bulbs need replacement every 6-8 months (never look directly into a UVC bulb; it could damage your eyes). For more replacement UVC bulbs, sleeves and parts see our UV sterilizer accessories.
