Pond UV clarifier bulbs should be changed annually, ideally in the spring. They perform well for roughly 12 months of continuous use, after which their performance rapidly drops off and they cease to work. Your UV Clarifier will still consume electricity when running spent bulbs, so always change them annually so as not to waste electricity, and to keep your pond water clear.
