Nyos Opus 200 G2 Aquarium and Cabinet

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)

ROBUST, SUSTAINABLE BUILD

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.
