The D-D Reef-Pro 1200 is a spacious marine aquarium system designed to provide all the essential features needed for a successful reef setup. Its wider-than-tall proportions create a balanced viewing area while making aquascaping, coral placement and ongoing maintenance easier. Aquarium Features The 120 × 60 × 46cm display aquarium is manufactured from 12mm low-iron, high-clarity glass, with polished edges and a clean, braceless design. A black-glass ‘invisible’ weir sits discreetly at the back of the aquarium, helping it blend into the background. The removable D-D UltraFlow weir comb allows 30–50% more water flow than a standard comb, while the twin-pipe overflow system provides safe and near-silent operation. The aquarium also includes a black vinyl background, pre-fitted base mat, complete pipework, a wide outlet nozzle and a random flow generator. Cabinet Features The extra-tall 120 × 60 × 102cm cabinet raises the aquarium to a comfortable viewing height while providing generous internal space for filtration equipment. Built in the UK, the heavy-duty cabinet features 36mm structural sections for strength and rigidity. It is supplied fully assembled with quick-release bi-fold doors, adjustable soft-close hinges, heavy-duty levelling feet and a large rear opening for ventilation and cable access. The 1200 model also includes a separate dry cabinet area for storing electrical equipment and other accessories away from the sump. Sump Features The Reef-Pro 1200 includes a 48-litre running-volume sump with two large multi-use chambers suitable for a protein skimmer, reactors, other equipment or a refugium. It also includes a dedicated return-pump chamber and an integrated 17-litre freshwater top-up reservoir. The sump is supplied ClariSea-ready as standard. A removable filter-sock assembly with a silencing plate is also available as an optional configuration when ordering.
