The Nyos OPUS G2 440 Slim-Line is a reef aquarium with a sump, featuring a rimless main tank, ultra-clear glass on the front and side panels, and an external overflow box mounted on the back. The overflow leaves more room for the reef structure in the main tank.
The Slim-Line cabinet is the same width as the main tank and takes up less floor space than the Pro-Line version. The cabinet's clean lines make for a compact aesthetic.
The cabinet is available in white or basalt grey. Please select your preferred color from the product options.
Features
- Transparent silicone seams and a deep blue back panel
- Moisture-resistant cabinet panels with a melamine resin finish

Sump and plumbing
The OPUS G2 includes pre-measured PVC plumbing and a multi-chamber sump. The main drain features an adjustable valve to control water flow and reduce drain noise. The system also includes a separate emergency drain.
The large main chamber of the sump provides space for a protein skimmer and other filtration equipment, such as a media reactor or algae reactor. The water level in the main chamber is approximately 21 cm.
