The Nyos OPUS G2 200 Pro-Line is a reef aquarium with a sump, featuring a rimless main tank, ultra-clear glass on the front and side panes, and an overflow box positioned on the outside of the back panel. The external overflow leaves more room in the main tank for reef structures.

The Pro-Line cabinet is wider than the main tank, providing extra space for equipment. The cabinet structure conceals the bottom silicone seam of the tank and the lower edge of the sand bed.

The cabinet is available in white or basalt grey. Please select your preferred color from the product options.

Features

• Transparent silicone seams and dark blue back panel
• Moisture-resistant cabinet panels with a melamine resin coating
• Pre-dimensioned PVC piping, adjustable main drain, and a separate emergency drain
• Nylon filter sock and a separate RO reservoir for top-off water

The Pro-Line cabinet features 125-degree Soft-Close hinges and adjustable feet.

Sump and piping

The OPUS G2 comes with a multi-chamber sump and pre-dimensioned PVC piping. The main drain includes an adjustable valve for fine-tuning water flow and drain noise, along with a separate emergency drain.

The large main chamber of the sump acts as a skimmer chamber and can also accommodate other equipment, such as a media filter or algae reactor, at the same time. The water level in the main chamber is approximately 21 cm.

Mechanical filtration is handled by a reusable nylon filter sock. A separate 16-liter top-off water reservoir can be connected to an auto-top-off system (purchased separately).
