As passionate aquarium hobbyists, each new setup brings an opportunity to fine-tune our designs and evolve toward the ideal reef system. With the D-D Reef-Pro Aquarium, we’ve distilled decades of continuous innovation into what we consider the ultimate system—versatile, affordable, and perfect for both novice and experienced aquarists. Every detail has been carefully considered to offer a robust, user-friendly aquarium that can meet even the most demanding expectations, while including all the essential features for a thriving reef.

Aquarium Features

• Ultra-Clear Glass: Crafted from low-iron, high-clarity glass with a braceless design and polished edges for a completely unobstructed view of your reef.
• Optimized Dimensions: A wider-than-tall aspect ratio enhances visibility, simplifies aquascaping, and facilitates coral placement.
• Invisible Weir Box: A sleek black glass design minimizes visual intrusion and improves flow dynamics inside the tank.
• Advanced Overflow System: Multi-stage weir and twin overflow pipes ensure high turnover and silent, safe operation—even in power outage scenarios.
• Ultra-Flow Weir Comb: Unique vertical and horizontal slots increase flow capacity by 30–50%, allowing higher return pump rates without raising water level.

ClariSea Compatibility

The included ClariSea-ready sump and plumbing simplify installation of the award-winning fleece filter system—no cutting or adjustments needed. Ideal for removing detritus, microalgae, and suspended particles, ClariSea enhances water clarity and quality in both marine and freshwater systems. Continuously developed over four years, it's suited for fish-breeding and coral propagation as well.

Flow Nozzles

Each system includes a 3D-printed flow generator and wide outlet nozzle, giving aquarists control to direct return flow precisely where it’s needed.

Ultra Flow Weir Comb

All D-D Reef-Pro tanks are fitted with the Ultra Flow Weir Comb, designed with a mix of vertical and horizontal slots to increase throughput while maintaining a lower water level. This smart design prevents overflow during power outages and allows higher flow without compromising stability. The weir comb is also easily removable for maintenance.
