Key Features

Exceptional Display Tank

• 53.9 Gallon (204 L) Display Volume: A deep, perfectly proportioned size for intricate reef aquascaping.
• Ultra-Clear Low-Iron Glass: The front and both side panes are made from low-iron glass, offering maximum clarity and color rendition by significantly reducing the green tint found in standard glass.
  
• Rimless "Pool Tank" Design: Features a clean, open-top aesthetic with no distracting side or cross bars. Only transparent silicone is used in the display tank for an unimpeded view. 
• Hidden External Overflow: The overflow box is discreetly recessed into the back pane. This frees up crucial internal space for aquascaping and makes cleaning the back glass simple.
• Deep Blue Back Pane: A dark blue lacquer on the back glass creates an impressive illusion of depth and a realistic underwater background effect.
  

Sleek Slim-Line Cabinet

• Space-Saving Minimalism: The cabinet matches the exact footprint of the aquarium, providing a slim design with clean lines that maximizes space in smaller areas.
• Basalt Grey Matte Finish: A modern, attractive grey with a sophisticated matte finish, available in this aesthetically pleasing, space-efficient model.
• Robust and Moisture-Resistant: Built with moisture-resistant boards (EN 312 compliant) and coated in a durable melamine resin, the surfaces are highly scratch- and impact-resistant. Includes waterproof pads on the inside floor.

• Comfortable Access: The cabinet has an increased height compared to the previous generation, making maintenance and work in the sump area more convenient. Doors feature a recessed push-to-open system.

Integrated Filtration System

• Pre-Assembled PVC Plumbing: The system includes durable, space-saving, and pre-assembled PVC piping—saving you time and effort on setup (no cutting or gluing required).
• Quiet and Safe Drain System: Utilizes a two-drain, Herbie-style configuration with an adjustable valve on the main drain to minimize noise, plus a separate emergency drain for safety.

• Functional 5-Chamber Sump: The spacious glass sump features a highly functional design with dedicated sections:

• Large Skimmer Chamber: Measures 9.5" x 20" (24 x 49.5 cm) with a constant 8-inch water level, optimized for housing a protein skimmer, media reactor, or other filters.
• Includes a Nylon Filter Sock to efficiently remove large debris.

• XL ATO Reservoir: A separate, generously sized refill tank holds 5.3 gallons (20 L) of RO water, providing a reliable supply for up to a week of auto top-off.
