Using a UV sterilizer in a reef tank

What is the sterilizer? It is a container, usually in a near tube shape, in which an ultraviolet (UV) fluorescent lamp is contained. The lamp emits light at around 254 nm. The lamp is constructed of quartz glass to prevent the UV being absorbed as it would be if ordinary glass were used. The lamp is in a container of its own to shield it from the water, and then there is an outer container. The space between the containers is very small allowing full penetration of UV light. The water is passed between the outer and inner containers by a pump or power head.
