SunSun 7W UV-C Steriliser – Anti-Algae UV Clarifier for Ponds & Aquariums

The SunSun 7W UV-C Steriliser is a compact and efficient 7W UV-C clarifier designed to maintain crystal-clear water in aquariums and garden ponds. Suitable for freshwater and marine aquariums, as well as ponds, it effectively controls green water, free-floating algae, bacteria, protozoa, and other harmful microorganisms without altering the natural chemistry of the water.

As water passes through the steriliser, it is exposed to 254 nm UV-C radiation, eliminating suspended algae cells and harmful microorganisms before they can reproduce. This results in healthier water conditions for fish and aquatic plants while naturally preventing green water without the use of chemicals.

Manufactured using a proven and reliable design, the SunSun UV-C Steriliser features high-quality components, durable seals, and excellent build quality. The unit is supplied complete with the UV bulb, hose fittings, and all components required for installation.
