The Nyos OPUS G2 250 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 overflow box positioned on the outside of the rear glass. The overflow leaves more space in the main tank for reef construction.

The Slim-Line cabinet is the same width as the main tank and takes up less floor space than the Pro-Line version. The clean lines of the cabinet suit a compact setup.

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 rear glass
• Moisture-resistant cabinet panels and melamine resin coating
• Pre-dimensioned PVC piping, adjustable main drain, and separate emergency drain
• Nylon filter sock and separate RO top-off water reservoir

Sump and piping

A multi-chamber sump and pre-dimensioned PVC piping are included. The main drain has an adjustable valve to regulate flow and drain noise, as well as a separate emergency drain.

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

Mechanical filtration includes a reusable nylon filter sock. An automatic water top-off system can be connected to the separate 20-liter top-off water reservoir.
