The NYOS OPUS 300 G2 is a modern aquarium and cabinet system developed for serious reef keeping. It combines a clear, open display with an organised technical area for filtration and maintenance.

The aquarium features an external rear overflow that leaves the display clear for aquascaping. Three sides use ultra-clear glass and transparent silicone, and the brace-free pool-style construction creates an open viewing experience. A deep-blue rear panel provides an attractive backdrop for reef livestock.

Below the aquarium is a generously sized filtration sump with a five-chamber arrangement, fixed PVC plumbing, an adjustable quiet drain and an emergency overflow. A separate extra-large freshwater reservoir is included for automatic top-off arrangements.

The cabinet is manufactured using moisture-resistant panels with a durable melamine surface and protected interior. SlimLine and ProLine cabinet designs and alternative finishes are offered. Check the cabinet selection and colour for the configuration you require.
