Nyos Opus 300 G2 Pro-Line White

Nyos Opus 300 G2 Pro-Line White

The Nyos Opus G2 300 Pro-Line elevates the impressive 262-litre system (plus 52 litres sump) with professional-grade features that reflect the demands of serious reef keepers. This premium variant incorporates height-adjustable feet that enable precise levelling on any surface, ensuring optimal water parameter stability and equipment performance. Standing at 141cm total height, the Pro-Line cabinet provides a slightly lower profile than the Slim-Line while delivering enhanced stability and refined engineering throughout.

Professional craftsmanship defines every aspect of the Pro-Line experience. Premium 125° hinges with soft-close functionality ensure smooth, controlled door operation that protects delicate corals and sensitive fish from sudden movements. The sand edge and front silicone seal are fully concealed, creating a seamless, gallery-quality aesthetic that reflects the exceptional engineering throughout the system. These meticulous finishing touches distinguish the Pro-Line as the choice for aquarists who demand both visual perfection and uncompromising functionality.

The ultra-clear glass specification—10mm thickness across front and side panes—delivers the same exceptional optical clarity as the Slim-Line variant. The hidden overflow design maintains visual purity, while the expanded sump system provides 52 litres of gross volume for comprehensive biological filtration and equipment housing. The refill tank (22 litres net), skimmer chamber (28 x 49.5cm), and return chamber (20 x 22cm) are optimally proportioned for efficient nutrient export and superior water circulation.

With a recommended flow rate of 2,000 l/h and an adjustable valve on the main drain, the Pro-Line 300 offers precise control over water movement and parameter stability. The moisture-resistant wood boards comply with EN 312 standards, ensuring durability in the humid aquarium environment. Available in elegant White or basalt grey colour options, this Pro-Line variant represents the pinnacle of large-capacity premium aquarium systems.
