SunSun CUV-111 11W UV-C Steriliser – Anti-Algae UV Clarifier for Ponds & Aquariums

The SunSun CUV-111 11W UV-C Steriliser is a reliable 11W UV-C clarifier designed to keep aquarium and pond water crystal clear. Suitable for freshwater and marine aquariums, as well as garden ponds, it effectively controls green water, free-floating algae, bacteria, protozoa, and other harmful microorganisms without affecting the natural chemistry of the water.

As water flows through the steriliser, it is exposed to 254 nm UV-C radiation, destroying suspended algae and harmful pathogens before they can reproduce. This helps maintain healthier water conditions for fish and aquatic plants while providing naturally clear water without the use of chemicals.

Built using a proven and reliable design, the SunSun CUV-111 features high-quality construction, durable seals, and efficient UV performance. The unit is supplied complete with the UV bulb, hose adaptors, and all components required for installation.
