Photocatalytically Enhanced Aquarium UV SteriliserThe photocatalytic lining of the Vecton Titan UV protects and further improves the lifespan of the high UV resistant plastic body. As with the rest of the award winning Vecton UV range; the Vecton Titan UV is designed with opposing inlet and outlet and comes with four stage hosetails for flexible hose from ½” to 1¼” for easy installation and connection to the water supply. These are held in place with screw on collars for easy removal when servicing and maintaining unit. There is a UV shield to prevent direct viewing of the UV lamp and the body is manufactured using impact resistant, translucent polycarbonate. Also included is an elbow connection, instruction manual, and a 3-year guarantee.The UV sterilisation process will only target the microorganisms floating in the water, so the good bacteria needed for processing ammonia remain healthy in your filter system, rock and substrate. UV technology used in fresh water or marine aquaria disrupts algae growth and kills bacteria and other pathogens that would otherwise cause disease in your aquarium inhabitants. This also allows much better light penetration, to the advantage of all animals in the aquarium. In addition to the health benefit of standard UV steriliser, the photocatalytic reaction in the Vecton Titan UV assures cleaner, more transparent water. Specifications Aquarium size - 550l / 121 imp.
