Lifegard Ultraviolet Sterilizer by Pentair Aquatics

Ultraviolet sterilizers kill free floating algae in ponds resulting in crystal clear water. The radiation from ultraviolet light at 2537 angstroms provided inside the Lifegard Ultraviolet Sterilizer exerts a lethal effect on micro-organisms. UV light alters genetic material within the cells, which interrupts respiration. UV light, when used properly, is extremely beneficial in destroying disease causing pathogens as they pass through the unit. UV sterilization is an effective method of disease control. Pure hard quartz material in the bulb dramatically increases UV output compared to other conventional bulbs of equal wattage. Pure quartz material resists solarization and improves the longevity of the bulb. Unique test tube style pure hard quartz sleeve isolates the bulb from water contact preventing thermal shock, broken glass and mercury contamination of the aquarium. This quartz sleeve isolates the bulb to provide an optimal bulb operating temperature of 100F (38C). This higher bulb temperature increases UV output 35% over conventional units without sleeves. Bulb changing is the easiest in the industry. Slide the old bulb out and slide the new bulb in. No need to shut down the filter system or turn off the pump. Bulb and ballast connect together with a single four-pin connector. UV radiation levels can be increased by slowing down the flow rate or increasing the total wattage in the system. Made in USA.
