The effective life of a replacement UV lamp is approximately 8000 hours. PondH2o’s compact PL-S H Type UV-C Germicidal Bulb allows for easy replacement.  The effective life of a UV lamp is approximate, after this point it will seem to be working but in fact the effectiveness of the lamp will be decreasing and need to be changed. Changing a bulb twice annually will usually be good enough to maintain the filter light unit.

UVC lamps in water garden ponds utilize ultraviolet light to destroy or control algae, bacteria, and parasites. The UV radiation disrupts their DNA, preventing them from reproducing and causing harm. This helps maintain water clarity, reduce disease, and promote a healthier pond environment.
