Key Benefits

• Reduces Harmful Bacteria & Fish Parasites
  Targets free-floating bacteria and parasites during their infectious stages, helping reduce disease risk and promote healthier livestock.

• Eliminates Green Water & Cloudiness
  Effectively removes turbidity caused by floating algae and bacterial blooms, resulting in crystal-clear aquarium water.

• High-Efficiency Reflector Technology
  Internal high-gloss aluminum reflector maximizes UV-C exposure by reflecting light through the water from multiple angles—making it up to 1.8× more effective than conventional UV sterilizers.

• Energy Efficient Performance
  Delivers powerful sterilization while maintaining low energy consumption compared to traditional UV units.

• Direct Flow Design – No Performance Loss
  Water flows smoothly around the UV-C lamp without redirection or detours, ensuring consistent sterilization without reduced flow efficiency.

• Safe for Biological Filtration
  Only targets free-floating organisms—beneficial bacteria in your filter media and substrate remain unaffected.

How It Works

The reeflexUV directs aquarium water as a thin film past a UV-C lamp, where ultraviolet radiation neutralizes microorganisms, algae spores, and pathogens. Unlike conventional units that irradiate from one side, the integrated reflector ensures multi-directional UV exposure, significantly increasing sterilization efficiency.
