The TMC Pro Pond Titan UV 110w is a professional pond clarifier that uses the latest photocatalytically enhanced ultra violet technology, making it up to 1.5 times more effective than a standard UVC. This produces hydroxyl radicals that improve water clarity through a process of oxidation. The completely contained photocatalytic reaction, provides a safer alternative to ozone, neutralising water born algae & oxidising organic compounds, resulting in clearer water.
