Lifegard Aquatics 120 watt UV Sterilizer


The radiation from ultraviolet light at 2537 angstroms provided inside the Lifegard Aquatics 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.

Four major factors affect the percent kill of free-floating micro-organisms by UV radiation:

  • Size of organisms.
  • Radiation level.
  • The extent to which UV rays penetrate the water.
  • Contact time in which the micro-organism is exposed to the UV radiation.

Pure hard quartz material in the bulb dramatically increases UV output compared to other conventional bulbs of equal wattage.

Bulb changing is the easiest in the industry. Simply 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 4 pin connector. UV radiation levels can be increased by slowing down the flow rate or increasing the total wattage in the system.
