• Adjustable Output up to 400 mg/h – High-performance ozone generation with precise adjustment to suit large aquariums and heavy bioload systems.
• Safe & Energy Efficient Operation – 12 V low-voltage ozone unit with external 110–240 V transformer; approx. 5 W power consumption and suitable for continuous use when correctly installed.

The 400 mg/h Ozone Generator is designed for large freshwater and marine aquarium systems requiring powerful and reliable ozone treatment. Using modern 12 V low-voltage technology, it delivers safe and energy-efficient operation suitable for continuous use when properly installed. By helping to prevent water yellowing, this unit promotes crystal clear water while increasing redox potential and enhancing protein skimmer performance. These improvements contribute to more stable water parameters and a healthier aquatic environment. Ozone treatment also assists in reducing bacterial load and supports the degradation of toxic nitrite. With a maximum adjustable output of up to 400 mg/h, this model is suitable for freshwater aquariums up to approximately 4,000 litres and marine aquariums up to approximately 2,500 litres, depending on stocking levels and system setup. Adjustable ozone output allows accurate adaptation to aquarium volume and bioload. The compact housing (approx. 178 x 84 x 46 mm) ensures convenient installation, and the 4/6 mm hose connection is compatible with standard aquarium air systems. Technical Specifications (400 mg/h Model): Maximum ozone output: up to 400 mg/h Power consumption: approx. 5 W Power supply (generator): 12 V Transformer input: 110–240 V / 50–60 Hz Air flow: approx. 200–500 l/h Suitable for freshwater aquariums up to approx. 4,000 litres Suitable for marine aquariums up to approx. 2,500 litres Dimensions: approx. 178 x 84 x 46 mm A high-output, adjustable ozone solution ideal for large and heavily stocked aquarium systems requiring superior clarity and enhanced water quality control.
