When should I replace the UV bulb in my EasyPro PCU35W Pro-Clear UV Clarifier?

[DelJackson]

For peak performance, replace the UV bulb in your EasyPro PCU35W Pro-Clear UV Ultra Stainless Steel Ultraviolet Clarifier annually. The manufacturer recommends replacement after 9000 hours of use, regardless of whether the bulb still emits light. Over time, the bulb's ability to eliminate algae decreases. Annual replacement ensures your clarifier effectively controls algae, maintaining a clear and healthy aquatic environment.
