OPUS G2 200 Slim-Line with White Cabinet
The NYOS OPUS G2 200 Slim-Line with a White Cabinet is a stunning 166 L (44gal) system with clean architecture, matte white finish, and discreet push-to-open functionality.
Furniture-Grade Design Premium Aquarium Performance & Quality
The Nyos OPUS G2 Slim-Line is where modern interior design meets world-class reef performance. Every system is crafted for reef keepers who want an aquarium that doesn’t just stand out — it fits in. The Slim-Line series combines the clean geometry of a minimalist display with the technical excellence of German engineering, creating a reef system that complements your home like a piece of fine furniture.
The Slim-Line cabinet sits flush with the aquarium footprint, forming a seamless silhouette with zero overhang. High-clarity low-iron glass panels, hidden overflow, and rimless construction ensure that every view is pure reef — elegant, clean, and unobtrusive.
Each OPUS G2 Slim-Line comes complete with a pre-plumbed sump, glass reservoir, and refill tank, making setup simple and maintaining your reef effortless. Built for those who want performance without clutter, it’s the perfect balance of form and function.
