At D-D, aquarium design is more than just engineering—it’s a passion shaped by years of hands-on experience. With each new setup, hobbyists learn, adapt, and refine, always in pursuit of the perfect system. The D-D Reef-Pro 1800 brings decades of development together in one complete, high-performance solution. Designed to be flexible, robust, and visually stunning, this system is equally suited for beginners and advanced aquarists.

From its ultra-clear display tank and ultra-quiet overflow system to its ClariSea-ready sump and thoughtfully engineered cabinet, every component has been carefully considered to deliver a premium reefkeeping experience.

Aquarium Features

• Crystal Clear Display: Braceless, low-iron ultra-clear glass with polished edges offers a clean, modern look and uninterrupted views of your reef.
• Optimal Dimensions: A wider-than-tall design enhances aquascaping, coral placement, and overall visual balance.
• Discreet ‘Invisible’ Weir: A sleek black glass weir blends seamlessly into the background while optimizing internal flow without obstructing your layout.
• Efficient Multi-Stage Weir: Promotes high water turnover while minimizing drain-down during power interruptions.
• Ultra-Flow Weir Comb: Allows 30–50% more water flow through the weir slots for increased return pump capacity without raising water levels.
• Twin Overflow Pipes: Ensures silent, fail-safe operation.
• Lighting Compatibility: Fully compatible with D-D Slimline brackets, OTM rail systems, and AquaIllumination lighting units.

Cabinet Features

• Extra-Tall Cabinet: Designed to offer the ideal viewing height while providing generous internal space for equipment and maintenance.
• Premium Construction: Built in the UK using 36mm structural panels for exceptional strength and load-bearing capacity—this is furniture-quality design, not just an aquarium stand.
• Smart Access Design: Features quick-release, bi-folding doors with soft-close, fully adjustable hinges for easy maintenance access.
• Pre-Assembled for Convenience: Delivered ready-to-use with a sleek, high-end finish.
• Adjustable Feet: Ensure the cabinet and aquarium are perfectly level, preventing stress on the tank and uneven water levels.
• Ventilation Built In: Designed to support airflow in both the sump and chiller sections.
• Dedicated Dry Section: Includes a dry compartment for secure storage of electricals or dry equipment.

Sump Features

• Designed by Hobbyists, for Hobbyists: Decades of reefkeeping experience have informed this simple yet efficient sump layout, tailored for performance and ease of use.
• Silent Operation: The twin-pipe overflow system feeds into a silenced intake chamber to eliminate noise and splash.
• ClariSea-Ready as Standard: The sump and pipework come pre-configured to fit a ClariSea unit with no cutting, tools, or pipework changes required.
• Generous Equipment Space: The sump includes separate chambers for skimmers, media reactors, calcium reactors, and more.
• Integrated Top-Up Reservoir: A 48L standalone reservoir is included for automatic top-off systems.

ClariSea Compatibility

Every Reef-Pro system is ClariSea-ready out of the box. ClariSea is a compact, high-efficiency mechanical filter that continuously removes fine particles, detritus, microalgae, uneaten food, and waste from the water column. Its patented design, refined over four years, ensures excellent clarity and water quality in both freshwater and marine systems—including coral propagation and breeding tanks.

Note: The ClariSea unit is sold separately.

Flow Control

Each Reef-Pro system comes equipped with a 3D-printed random flow generator and wide outlet nozzle. This allows you to direct flow from the return pump exactly where it's needed, helping to create ideal circulation patterns throughout the tank.

Ultra Flow Weir Comb

All Reef-Pro tanks feature the innovative Ultra Flow Weir Comb. Unlike standard vertical designs, this unique comb includes both horizontal and vertical slots, increasing flow capacity by up to 50%. This ensures optimal flow without raising the water line, while also reducing drain-down risks during a power cut. The comb is fully removable for easy cleaning.
