TMC (Tropical Marine Centre) pioneered the development of the UV Cleansing system and has manufactured them since the late 1970s. This UV Pro Clear Advantage works by halting the reproduction of algae.
The ultraviolet radiation at a wavelength of 254 nanometers is extremely effective in doing so. At the heart of this is an ultraviolet lamp sealed inside a quartz sleeve. As water is pumped through the unit, ultraviolet light from the lamp destroys the green, single celled water borne algae (which makes garden ponds murky and unattractive), this will leave the water crystal clear.
The benefit of this is that there is no adverse effect on sensitive plant and pond life. It is easy to use with translucent hose connectors which glow to show that the lamp is working. It is designed for long life.
