The NYOS OPUS 440 G2 pairs a spacious reef aquarium with a high-quality matching cabinet and a practical filtration arrangement. The system has been designed to place attention on the reef while keeping the surrounding equipment discreet.

The overflow runs externally against the rear pane, retaining valuable display space for rock structures and corals. Ultra-clear glass is used on the front and sides, with transparent silicone joints for clean edges. The open, cross-brace-free pool design provides uninterrupted viewing, complemented by a deep-blue back panel.

The aquarium is supplied as a reef-ready system with a generously proportioned technical sump and a separate XL freshwater refill tank. Cabinet construction includes moisture-resistant materials, a hard-wearing melamine finish and practical access to the equipment area.

Available cabinet options include SlimLine and ProLine styling and white or Basalt Grey finishes. Confirm the selected cabinet and colour combination when purchasing.
