Biopro Hopar Jebao 18W UV BULB

Have you got a 18 Watt steriliser but you water feature or pond is going green ? Not from envy but from Algae? Are you fish competing for oxygen due to algae ? It is most likely that your UV Bulb Globe needs to be replaced. Although the UV Lamp in a Ultra Violet Clarifier (UV-C) will last over 12 months, the effectiveness of the lamp declines over time.  That's why the manufacturer recommends replacing the UV Lamp tube every 12 months, so your pond or water feature can look its best all year round.
