UVC Bulbs help keep your pond free from algae, ensuring crystal clear water all year round. The UVC radiation from your UV bulb will destroy the algae cells present in your water, the remnants of which are then broken down further by your pond filter. With time, the UV output of the bulb degrades over time, so periodic replacements are recommended.
