WithNyos® OPUS®, we created a ready-to-use reef aquarium that will satisfy the highest demands in terms of quality, functionality, and aesthetics. Attention has also been placed on important details, which make the difference. Through the minimalistic design, the aquarium itself melts into the background. In this way, nothing detracts from the most important aspect: The reef experience.
Clear glass edges
In order to detract as little as possible from the reef experience, only transparent silicone is used in the display aquarium.
Three sides with ultra-clear glass for brilliant colors
The front pane and both side panes are each produced from ultra-clear glass. In comparison to conventional glass, ultra-clear glass exhibits a significantly weaker green tint, so that the colors of the fish and corals appear much more richly contrasting and lively.
The Nyos® OPUS® is equipped with an external overflow box recessed in the back pane. With no interfering overflow box inside the aquarium, additional space is available for aquascaping. It is also simple and straightforward to keep the back pane clean.
The aquarium is recessed in the cabinet. This conceals the often unsightly bottom silicone seam, as well as the sand edge of the aquarium. With this, the view of the reef is entirely unimpeded.
Deep blue lacquered back pane for realistic depth effect
The back pane of the aquarium is finished in a precisely tailored dark shade of blue. When the aquarium lighting is switched on, this creates the perfect illusion of a realistic underwater world with depth effect.
Cubic cabinet design
The cubic cabinet design delivers the OPUS®-typical, distinctive look and perfectly sets the reef as the central feature.
Within the framework of pre-assembly in the factory, all external gaps and seams in the cabinet are sealed. This results in a perfectly seamless finish as if cast from a single piece.
Full-surface all-round lacquered finish
The entire surface of the Nyos® OPUS® cabinet is finished internally and externally with multiple layers of lacquer. This provides additional internal protection against saltwater and ensures the cabinet is particularly durable. The exterior exhibits the OPUS®-typical, perfectly seamless finish in a matt look.
The sophisticated design of the sump for multi-stage filtration
The sump is equipped with 6 chambers. The return water initially flows into a settling chamber, before being fed through a fine filter (filter bag). This is followed by a forced-flow, free filter chamber. It is possible to introduce filter media such as active carbon, zeolite or similar in this chamber if necessary. The large main chamber exhibits a constant water level of approx. 21cm (8.5 in) and is therefore ideal for Nyos®QUANTUM® skimmers. A bubble trap is installed in front of the return chamber, in order to reduce any micro-bubbles that may arise.
Space-saving integrated auto top-off system
An integrated mechanical auto top off system ensures compensation for water lost through evaporation. The refill tank optimally utilizes the free space in the area of the return chamber.
