The OASE 11-watt UVC replacement bulb provides optimum UV radiation levels to tackle the issue of single-celled suspended algae (the cause of green water) in ponds and water features. The ultraviolet radiation causes microscopic suspended algae to flocculate (clump together) and this larger biomass can then be passed to the pond filter for removal.
