NYOS OPUS G2 250 Pro with White Cabinet

The NYOS OPUS G2 250 Pro-Line with a White cabinet features a 204L (54 gal) aquarium, pairing modern minimalism with quiet precision for a display worthy of a gallery but perfect for your home.



Professional Reef Performance with Designer Integration

The Nyos OPUS G2 Pro-Line series represents the evolution of functional art — a professional reef system engineered for advanced aquarists who demand precision and visual harmony. Each Pro-Line model offers deeper dimensions, expanded filtration capacity, and a full-depth cabinet engineered for superior strength, acoustic isolation, and long-term durability. The result is a design that is almost as eye-catching as the living reef that will be growing within it. 

Every system is built in Germany under the Nyos ethos of “High Level Reefing – Made in Germany.” The result is a reef-ready platform that performs like laboratory equipment yet looks like fine furniture — quiet, sleek, and architecturally balanced to fit seamlessly into modern interiors.
