UVC Filter Spares

UV clarifiers are essential to deal with the algae that create green water, but the bulbs lose their effectiveness and each year your should purchase Pond UVC Lamp Replacements. Single cell algae can pass through a normal filter but the UV lamp clumps them together and it is these clumps of algae that are trapped and dealt with by the filter, this porcess becomes less effective as the UV lamp gets older. That's why we always recommend changing the bulb regularly and making sure the O ring hasn't deteriorated.
