The Nyos® OPUS® 300 (Slim Line) G2 is a premium saltwater aquarium designed for the discerning aquarist who makes no compromises on quality, functionality, and appearance. This aquarium combines a timeless design with innovative details, ensuring your reef becomes the shining centerpiece of any room.

An unparalleled viewing experience

Thanks to the use of ultra-clear glass on the front and sides, you enjoy a razor-sharp view of your corals and fish. The glass has hardly any green tint, making colors appear more vibrant and richer in contrast. The deep blue background creates a realistic depth effect and brings the reef even more to life.

• Ultra-clear glass for perfect color reproduction
• Deep blue backdrop for extra depth
• Sleek finish with transparent silicone

Functional and well-thought-out design

The Nyos® OPUS® 300 G2 distinguishes itself with its smart, external overflow system. The overflow is completely concealed within the back wall, giving you ample space to create a spectacular aquascape. No unsightly overflow box inside the aquarium and easy maintenance of the back wall.

• Hidden external overflow for maximum aquascaping surface area
• No obstructing beams or sleepers
• Extra deep dimensions for creative layout

High-quality Slim Line cabinet

The matching Slim Line cabinet is finished in stylish grey and crafted from moisture-resistant materials, featuring a scratch-resistant melamine top layer. The cabinet is not only durable but also practical: thanks to the generous height and the push-to-open system, you work comfortably and always have easy access to the technical equipment.

• Robust, moisture-resistant cabinet according to EN 312
• Made from sustainable wood with FSC® certification
• Convenient push-to-open doors
• Space for all necessary equipment

Optimized technical room

Beneath the aquarium, you will find a spacious sump with a large skimmer compartment and a separate refill reservoir. The layout is designed for maximum flexibility and easy installation of filters, skimmers, and return pumps. Thanks to the well-thought-out design, the system is quiet, safe, and easy to maintain.
