Utilizing a UV (ultraviolet) light in a water garden or pond is mainly aimed at clearing green, murky water resulting from single-celled algae blooms. It is important to inspect your UV light at least once each season to confirm its proper functioning. Replacing worn seals or damaged quartz glass is crucial for maintaining its effectiveness over time. When the UV light starts to lose its efficacy, it is necessary to replace the bulb, as UV bulbs should be changed annually to ensure optimal performance.
