UV Sterilizer

UV Sterilizers are the devices emitting high intensity UV Rays to sterilize an aquarium by killing infectious Bacteria, Parasites, Floating Algae, Fungus, Virus, and the other harmful Microorganisms present therein. UV Rays influence a cell’s functionalities by changing the structure of its nuclear content or DNA. This nuclear meddling hinders cellular respiration and eventually proves lethal to the affected organisms. This negativity of UV Rays is exploited in UV Sterilizers to kill harmful beings present in an aquarium, especially the Marine one. Fresh Marine brings a wide collection of UV Sterilizers. The ensuing discussion explores some of these UV Sterilizer options.

UV Sterilizer Replacement Bulb. UV Sterilizer Replacement Bulbs generate the UV Rays emitted by UV Sterilizers.

UV Sterilizer Replacement Bulbs by Pentair Aquatics.
  • Pentair Aquatics (Rainbow Lifegard) Replacement UV Bulbs. Made of pure hard Quartz, these UV Sterilizer Replacement Bulbs generate high UV output. The high quality Quartz employed here also resists Solarization, due to which the UV Bulbs last long. These UV Sterilizer Replacement Bulbs have Test Tube styled, pure hard Quartz Sleeve to protect them from water exposure, which in turn averts the risks of Thermal Shock, broken Glass, and Mercury leakage in the aquarium. The Quartz Sleeve isolation also enables a UV Sterilizer Replacement Bulb to emit the maximum temperature of 100°F (38°C). Pentair Aquatics (Rainbow Lifegard) 8 W Replacement UV Bulb 175229, 25 W Replacement UV Bulb 175230, and 40 W Replacement UV Bulb 175231, are the options in the range.

  • Pentair Aquatics (Rainbow Lifegard) AquaStep Replacement Bulbs. A 10 W UV Sterilizer Replacement Bulb measures 13.39”, a 15 W Bulb measures 15.35”, and a 25 W Bulb is 17.83” long.


  • UV Sterilizer Quartz Sleeves. UV Sterilizer Quartz Sleeves protect the UV Sterilizer Bulbs from water exposure, which in turn averts the risks of Thermal Shock, broken Glass, and Mercury leakage in the aquarium. The Quartz Sleeve isolation also enables a UV Sterilizer Replacement Bulb to attain the maximum operating temperature of 100°F (38°C).
  • Pentair Aquatics (Rainbow Lifegard) Quartz Sleeve. Specific types of UV Sterilizer Quartz Sleeves come for particular UV Sterilizers.
