D-D The Aquarium Solution D-D Reef-Pro 600 - Platinum Oak

As hobbyists, with each new aquarium that we own we learn how to identify and improve small details in the design and incorporate these ideas into our next 'perfect system'. With the D-D Reef-Pro Aquarium we have taken decades of continuous improvements and incorporated them into our own version of the 'perfect system', affordable and suitable for both beginners or advanced aquarists. The flexible design provides an easy to use robust system that can be tailored to suit even the most demanding aquarist and includes all of the essential features required for keeping a successful aquarium.


  • Crystal clear, braceless aquarium with full polished edges to give an unimpeded view of your own personal reef.
  • Balanced width to height ratio to enhance viewing, aquascaping and ease of coral placement.
  • Unique 'Invisible weir box' design in black glass which almost disappears into the back of the aquarium.
  • Multi-stage weir design provides a high turnover rate in the tank whilst minimising drain down levels in a power loss situation.
  • Special 'Ultra-Flow' weir comb allows 30-50% more water through, so that larger flow rates can be used.
  • Twin overflow pipes offer safe, silent operation.
  • Perfectly matched for use with the D-D Slimline lighting bracket, D-D OTM Rail system and AquaIllumination lighting.
  • Sleek, extra tall cabinet that offers the perfect viewing height for the aquarium. 
  • Modern, heavy duty cabinet construction with high quality finish to compliment the home environment.
  • Extra height internal space for installation and maintenance of equipment.
  • Cabinet supplied pre-assembled as standard.
  • Removable quick release, bi-folding doors to offer improved access for maintenance.
  • Lacquer coated, fully adjustable, soft close hinges.
  • Adjustable feet to allow correct levelling of the aquarium on uneven floors.
  • Good ventilation incorporated into the chiller and sump areas
  • Filter sock with silencing plate (Option when ordering).
  • Sump supplied ClariSea ready as standard.
  • Large skimmer / equipment section.
  • Pump chamber.
  • Built in top-up reservoir.
Aquarium Features

Constructed from crystal clear, low iron high clarity glass, the aquarium features a braceless design, producing a clean and modern display with easy access for maintainance.

By designing the tank to be wider than it is tall we create a more balanced aspect ratio which greatly enhances the viewing experience, allowing easier and more natural aquascaping and coral placement.

An internal weir box can become an unattractive focal point in any aquarium, dictating aquascaping and interupting flow patterns inside the tank.With this in mind the 'invisible weir box' of the PRO-Reef models has been carefully designed to minimise intrusion into the aquarium whilst exceeding the functionality found in most aquariums.

The Twin pipe overflow system allows almost silent running whilst the use of the D-D UltraFlow weir comb allows the maximum amount of waterflow without raising the water height in the aquarium.

More details on UltraFlow are provided further down this page.

Cabinet Features

The PRO-Reef cabinet is designed to be extra tall to perfectly balance the aspect ratio of the aquarium and is built for D-D in the U.K to ensure a consistent high quality. 

The top, bottom and front structural uprights of the cabinet are made of 36mm board, making it extremely strong and rigid with excellent load bearing properties, giving the impression of a piece of furniture rather than just a simple tank cabinet. Note that as with any piece of furniture, spilled or standing water must be cleaned up immediately from the surface to prevent damage to the board.

The extra internal height inside the cabinet provides good headroom for use of taller equipment and benefits ease of maintainance. Access is further improved by incorporating removable quick release. double folding doors.

When installing any aquarium it is of the upmost importance to provide a level base, unlevelled cabinets can add stress the glass and can result in an uneven water level in the aquarium. The D-D aquarium cabinet design includes heavy duty adjustable feet allowing for full levelling of the cabinet and aquarium.

Sump Features

There are as many ideas about sump design as there are hobbyists.D-D have many decades of experience in designing, building and running large successful aquariums and have combined this knowledge to produce what we believe is the perfect simple sump layout for the space available.

The ultra quiet twin pipe weir system is further refined by the first section of the sump, resulting in a silent water return with no splashing or gurgling. If using the filter sock arrangement (option when ordering), the water then overflows into a twin filter sock section which incorporates a diffused silencer plate to reduce any water noise. The Reef Pro aquariums come as standard with a ClariSea ready sump, with this the filter sock section, if used, can be lifted out and replaced with a ClariSea unit with ease even when the aquarium is filled with water. The main overflow pipework provided will drop directly in to the ClariSea inlet fitting, so no cutting or changing of pipework is required.

After passing through the prefilter water flows into a large equipment compartment. This chamber can both hold equipment such as skimmers, media reactors, calcium reactors etc.

The final section is a return pump compartment which sits beside the integrated water top off reservoir.

ClariSea Ready

As standard the D-D Reef-Pro range is supplied with a ClariSea ready sump and pipework, this allows the ClariSea units to be fitted easily with no adjustments or modifications.The ClariSea fleece filter is an ultra compact, patented, high efficiency water filtration system, which continuously removes suspended particles such as micro algae, detritus, food, organic waste and gravel dust from the water column to improve water quality and clarity. The ClariSea design has been continuously developed and improved over 4 years, and is suitable for use in both marine and freshwater aquariums, fish-breeding and coral propagation systems.

Flow Nozzles

The D-D Reef-Pro aquariums come complete with a 3D printed flow generator and wide outlet nozzle attachment allowing the flow coming from the sump to be directed and taylored to suit your reef.

Ultra Flow Weir Comb

All D-D Reef-Pro aquariums come fitted with the Ultra Flow Weir Comb to allow maximum water flow through the weir without excessively raising the water level in the aquarium. The Ultraflow Overflow Weir Comb maintains a high flow at all times, allowing the use of larger return pumps with a higher flow rate.

The D-D Ultraflow Overflow Weir Comb is designed with a unique araingement of vertical and horizontal drain slots that allows around 30% to 50% more water to flow through the slotted sections compared to a standard vertical type weir, which in normal circumstances, can result in a much higher running level causing excess drain down in the event of a power cut or in the worst case scenario the aquarium overflowing.

For maintanence the weir comb can easily be removed and cleaned.
