UNS Reef System - R80CS

The UNS Reef System delivers a refined, reef-ready solution available in a range of thoughtfully designed sizes. The R line of rimless aquariums showcases UNS’s signature 45° mitered edges, black silicone seams, and thicker ultra-clear glass, engineered for long-term durability and exceptional clarity. Each system is paired with a matching aluminum-framed stand and an integrated sump filtration system, creating a cohesive and professional setup from top to bottom. Magnetic, fully removable doors allow for effortless access, streamlined maintenance, and personalized equipment layouts. Larger models also include built-in storage drawers to keep essential aquarium supplies organized and within reach. Every detail of the UNS Reef System has been carefully considered to strike the ideal balance between functionality, performance, and modern aesthetics. Learn more about the features below.

The R80CS features the same footprint as the R80 Frag holding tank, while incorporating the back chamber of our standard reef systems.

Rimless Aquarium Features

• Signature 45° mitered edges combined with low-iron, high-clarity glass provide an immersive viewing experience and allow for close, edge-to-edge cleaning with preferred glass cleaning tools or algae scrapers.
• Black silicone subtly conceals coralline algae buildup for a cleaner, more refined appearance.
• Thicker glass construction eliminates the need for euro-bracing while maintaining structural integrity.
• A sleek white bottom panel supports bare-bottom reef setups while keeping sump equipment visually concealed.
  

Aquarium Cabinet & Sump Features

• The R80 and R80CS include an integrated electrical cabinet and pull-out storage drawer located on the right side of the stand.
• The low-profile overflow box features intake slots at both the top and bottom, along with an internal vertical glass baffle that helps protect against main tank flooding in the event of pump failure.
• The overflow lid is constructed from durable polycarbonate for improved heat resistance and reduced warping, while additional covers are flush-fitting and easily removable to minimize salt creep.
• Fully removable magnetic doors eliminate the need for traditional stainless steel hinges, increasing corrosion resistance and simplifying access.
• The stand arrives fully assembled with the sump pre-installed, allowing for quick setup and straightforward plumbing—simply place the tank, connect the pre-glued pipes, and secure each union with easy twist-on fittings.
• Pre-cut wire management ports help keep cables organized and out of sight.
  A built-in controller box provides a dedicated space for surge protectors and clean cable routing.
• Removable controller boards allow easy access from the side door while keeping wiring neatly managed.

Sump Filtration System Features

• Included gate valves ensure precise water flow control and quieter operation. A supplemental ball valve and barbed fittings are included on the return line for optional external equipment such as reactors or chillers. A gasket beneath the drainpipe and sump helps reduce salt creep buildup.
• The multi-chamber sump incorporates a pre-filter baffle designed to capture larger debris using filter floss, extending the time between filter sock changes. Diffuser plates help reduce noise and prevent filter socks from floating during maintenance.
  The second chamber accommodates a wide range of protein skimmers, with adjustable water levels via an acrylic baffle to support varying skimmer height requirements.
• The third chamber can be configured for additional filtration media or used as a refugium, with adjustable water levels for added flexibility.
• The fourth chamber is designed to house return pumps and heaters.
• The R80 and R80CS include a built-in ATO reservoir positioned in front of the first chamber for convenient top-off management.
