With the Nyos® OPUS® G2 series, we have created ready-to-use reef aquariums that meet the highest demands in terms of quality, functionality and aesthetics. Attention has also been paid to important details that make the difference. The special design places the aquarium as such in the background. As a result, nothing distracts from the most important thing: the reef experience.

Hidden overflow

The Nyos OPUS G2 is equipped with an external overflow box that is recessed into the back wall. Without a disturbing overflow box in the aquarium, there is additional space available for aquascaping. It is also easy to keep the back wall clean.
Windows with ultra-clear glass for brilliant colours

The front wall and both side walls are made of ultra-clear glass. Compared to conventional glass, ultra-clear glass shows a significantly weaker green tint, so that the colors of the fish and corals appear more contrasting and vivid.

Swimming pool tank

The Nyos OPUS G2 is designed as a swimming pool tank. There are no annoying side or cross bars in the aquarium.
Clear glass edges

To distract as little as possible from the reef experience, only transparent silicone is used in the display tank.
Deep blue back wall for realistic depth effect

The back wall of the aquarium is finished in a finely tuned dark shade of blue. When the lighting is switched on, it creates the perfect illusion of a realistic underwater world with depth effect. Perfect aquascaping dimensions thanks to the extra depth

For reef aquariums, depth is extra important when it comes to aquascaping. That's why the Nyos OPUS G2 has an extra deep design, so you can create spectacular aquascapes.
