The Nyos OPUS G2 250 Pro-Line is a reef aquarium system with a rimless display tank, featuring ultra-clear glass on the front and side panels, and an external overflow box located on the back. The overflow provides more space for the reef structure inside the main tank.

The Pro-Line cabinet is wider than the main tank and offers extra space for equipment. The cabinet design conceals the bottom silicone seam 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 a dark blue back panel
• Moisture-resistant cabinet panels with a melamine resin coating
• Pre-measured PVC piping, adjustable main drain, and a separate emergency drain
• Nylon filter sock and a separate RO top-off reservoir

The Pro-Line cabinet features 125-degree soft-close hinges and adjustable feet.

Sump and piping

A multi-chamber sump and pre-measured PVC piping are included. The main drain features an adjustable valve for fine-tuning the flow and minimizing noise, along with a separate emergency drain.

The large main chamber of the sump serves as a skimmer chamber and provides space for other equipment, such as a media reactor or algae reactor. The water level in the main chamber is approximately 21 cm.

Mechanical filtration is provided by a reusable nylon filter sock. An automatic top-off system can be connected to the separate 20-liter RO reservoir.
