Nyos Opus G2 300<\/p>\n

\n

Quality. Function. Aesthetics.<\/span><\/h2>\n

With the \u00ae OPUS\u00ae series we created ready-to-use reef aquariums that will satisfy the highest demands in terms of quality, functionality and aesthetics. Attention was also paid to important details that make the difference. Due to the special design, the aquarium as such is placed in the background. As a result, nothing distracts from the most important thing: The reef experience.<\/p>\n

Key Features Nyos\u00ae\u00a0OPUS\u00aeG2<\/strong><\/p>\n

    \n
  • Hidden overflow: External overflow box embedded in the back pane<\/li>\n
  • Pool tank with ultra-clear glass and clear edges thanks to transparent silicone<\/li>\n
  • Deep blue back pane creates a realistic feeling of depth<\/li>\n
  • With the Slim-Line\u00ae\u00a0and Pro-Line\u00ae, you can choose from two cabinet design lines<\/li>\n
  • High-quality, robust cabinets thanks to the melamine resin coating<\/li>\n
  • Separate refill tank with extra large capacity<\/li>\n
  • Large sump with a functional design as well as big skimmer chamber for multiple devices<\/li>\n
  • Made in the EU with improved sustainability aspects<\/li>\n<\/ul>\n

    MINIMALISM PERFECTED<\/p>\n

    Panes with ultra-clear glass for brilliant colors<\/strong>
    \nThe front pane and both side panes are 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 more contrasting and lively.<\/p>\n

    Pool Tank<\/strong>
    \nThe Nyos\u00ae OPUS\u00ae G2 is designed as a pool tank. There are no annoying side or cross bars in the aquarium.<\/p>\n

    Clear glass edges<\/strong>
    \nIn order to detract as little as possible from the reef experience, only transparent silicone is used in the display tank.<\/p>\n

    Deep blue lacquered back pane for realistic depth effect<\/strong>
    \nThe back pane of the aquarium is finished in a precisely tailored dark shade of blue. When the lighting is switched on, this creates the perfect illusion of a realistic underwater world with depth effect.<\/p>\n

    Perfect aquascaping dimensions thanks to the extra depth<\/strong>
    \nFor reef aquariums, depth is particularly important when it comes to aquascaping. That’s why the Nyos\u00ae OPUS\u00ae G2 features an extra deep design so you can create spectacular aquascapes.<\/p>\n

    NYOS\u00ae OPUS\u00ae G2 CABINET<\/h3>\n

    The Nyos\u00ae OPUS\u00ae G2 is optionally available with \u00ae or Slim-Line\u00ae cabinet.<\/p>\n

    Both cabinet designs are characterized by the following features:<\/p>\n

    Robust design<\/strong>
    \nBoth cabinet designs use moisture-resistant boards in accordance with EN 312. Thanks to a durable melamine resin coating, the surfaces are extremely scratch and impact resistant. Furthermore, the cabinets are equipped with water-proof pads on the inside.<\/p>\n

    Sustainable and resource-friendly<\/strong>
    \nThe wood used in the Nyos\u00ae OPUS\u00ae G2 cabinets comes from verified legal sources in accordance with ISO 38200 and is produced in FSC\u00ae certified factories. The legal limits for formaldehyde emissions are clearly undercut. All cabinets are made of 30% from recycling material and 45% co-products (leftover wood from the sawmill industry). This results in a lower carbon footprint.<\/p>\n

    Comfortable with greater height<\/strong>
    \nCompared to the first generation, the Nyos\u00ae OPUS\u00ae G2 cabinets have a greater total height so that working in the cabinet is more convenient. The doors can be conveniently opened with the recessed push-to-open system.<\/p>\n

    Aesthetics and design<\/strong>
    \nWith the Nyos\u00ae OPUS\u00ae G2 cabinets, we paid special attention to functional and aesthetic design. The surfaces have a melamine resin coating and are timeless elegance and simplicity.<\/p>\n

    Available in two attractive colors<\/p>\n

    In addition to timeless white, both cabinet types are also available in modern basalt gray. Both colors are characterized by a matt finish.<\/p>\n\n\n\n\n\n

      NYOS\u00ae OPUS\u00ae G2 SUMP\"\"<\/h3>\n

      CLEAR & CLEAN<\/h3>\n

      Space-saving PVC piping<\/strong>
      \nCompared to hose installations, PVC piping offers greater safety and durability. The piping can be installed in a few simple steps and is designed to be space-saving.<\/p>\n

      Simplified sump with large skimmer chamber<\/strong>
      \nMultiple devices such as skimmer, media reactor or algae reactor can be housed at the same time in the large main chamber (skimmer chamber). This chamber has a constant water level of approx. 21 cm (8 in).<\/p>\n

      Adjustable, quiet main drain and separate emergency drain<\/strong>
      \nThe Nyos\u00ae OPUS\u00ae G2 has a main drain with an adjustable valve. This makes it possible to minimize drain noise. An emergency drain is also included as standard..<\/p>\n

      Nylon filter sock<\/strong>
      \nThe Nyos\u00ae OPUS\u00ae G2 includes a nylon filter sock. It is designed for longer run times.<\/p>\n

      Separate, large volume refill tank<\/strong>
      \nThe 50cm (20 in) high refill tank with a volume of 22 liters (6 gal) holds RO water for about one week.<\/p>\n

      Functionality and Structure of Sump<\/h3>\n

      Chamber 1<\/strong>
      \nSedimentation chamber for the outflow water from the display tank.<\/p>\n

      Chamber 2<\/strong>
      \nFilter sock filters dirt particles out of the water<\/p>\n

      Chamber 3<\/strong>
      \nThe main filter chamber, also known as the skimmer chamber, has a constant water level. It is possible to install further filters here, such as a media reactor for example.<\/p>\n

      Chamber 4<\/strong>
      \nBubble trap, in which a coarse filter sponge can be placed if necessary.<\/p>\n

      Chamber 5<\/strong>
      \nReturn Chamber. In this chamber, the water is fed back into the display tank via the return pump. As the water level in the return chamber varies, this is where the evaporated water needs to be replenished via the auto top off system.<\/p>\n
