The Nyos OPUS G2 440 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 external overflow box mounted on the back. The overflow leaves more room for aquascaping in the main tank.
The Pro-Line cabinet is wider than the main tank, providing extra space for equipment. The cabinet structure hides the tank's 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.

- Moisture-resistant cabinet panels and melamine resin surface
