PHILLIPS 11W UV Globe

The UV (ultraviolet) globe in a pond pressure filter is responsible for emitting UV light, which helps control algae and harmful microorganisms in the pond water. To maintain the effectiveness of the UV treatment, it’s essential to replace the UV globe at the appropriate intervals. Here are some indications that it may be time to replace the UV globe in your pond pressure filter:

1. Decreased UV Output: Over time, UV bulbs lose their effectiveness, and their output diminishes. If you notice a decline in the clarity of your pond water or if algae growth becomes more prominent, it may be an indication that the UV globe is no longer emitting sufficient UV light.
2. Elapsed Lifespan: UV bulbs typically have a limited lifespan, usually measured in hours of use. 8,000 operating hours – 11 months
3. Visual Inspection: Examine the UV globe for any signs of damage, such as cracks or discoloration. Damaged bulbs may not function correctly, and the UV light may not penetrate the water as intended.
4. Ineffective Algae Control: If you’re experiencing persistent issues with algae growth, and other factors such as water quality and filtration are in check, it may be an indication that the UV globe needs replacement.
5. Regular Maintenance Schedule: Some pond owners prefer to replace the UV globe as part of their regular maintenance routine, even if it seems to be working fine. This proactive approach ensures that the UV system continues to operate at its best.
