The NYOS OPUS G2 series brings a ready-to-use reef aquarium system that blends premium quality, functionality and minimalist aesthetics—so nothing distracts from the main attraction: your reef.
THE NYOS OPUS G2 AQUARIUM
(OPUS G2 TANK)
HIDDEN OVERFLOW
An external, rear-embedded drain shaft sits flush with the back pane—freeing the display from a bulky overflow for more aquascaping space and easy cleaning.
THREE SIDES ULTRA-CLEAR GLASS
Ultra-clear front and side panes reduce green tint for vibrant, high-contrast fish and coral colors.
POOL DESIGN, CLEAR EDGES
No side or cross braces and transparent silicone keep the view pure and unobstructed.
DEEP BLUE REAR PANE
A precisely tuned dark blue back creates a natural depth effect under illumination.
AQUASCAPING-FRIENDLY DEPTH
Extra depth enables dramatic, stable reef structures and natural layouts.
THE NYOS OPUS G2 CABINET
(OPUS G2 CABINET)

THE NYOS OPUS G2 TECHNICAL TANK
(OPUS G2 SUMP)
SPACE-SAVING PVC HARD PLUMBING
Durable, secure PVC piping installs in a few steps and maximizes cabinet space.
GENEROUS MAIN CHAMBER
A simplified sump with a large constant-level chamber (~21 cm) fits skimmers, media reactors and algae filters simultaneously. Includes nylon filter sock for long service life.
QUIET OPERATION + SAFETY
Adjustable drain valve reduces noise; an emergency overflow is standard.
SEPARATE XL ATO RESERVOIR
An extra-tall refill tank supplies evaporation water for about one week.
5-CHAMBER PRINCIPLE
1) Settling chamber; 2) Filter sock; 3) Constant-level filter chamber for skimmer/reactors (e.g., Nyos TORQ); 4) Optional sponge bubble trap; 5) Return chamber with variable level for ATO sensor placement.
Engineered for reef-ready performance and modern living spaces, this system delivers crystal-clear viewing, quiet reliability, and intuitive maintenance—ideal for aquascapers and coral enthusiasts seeking a refined, high-quality marine aquarium setup.
