D-D Reef-Pro 1200 (ClariSea Sump) – Driftwood Concrete (Matt)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.System HighlightsAquariumCrystal 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.Dry Box built into weir section to hide and pass through any pump and lighting cables.Perfectly matched for use with the D-D Slimline lighting bracket and Aqua Illumination lighting.CabinetSleek, 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 door 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.Separate chiller section with storage shelf included on larger models.SumpTwin filter socks with silencing plate.Lift out filter sock section for easy ClariSea installation.Large skimmer / equipment section.Refugium section for Caulerpa bed or for growing coral frags.Pump chamber.Large top-up reservoir. Aquarium FeaturesConstructed from crystal clear, low iron high clarity glass, the aquarium features a braceless design, producing a clean and modern display with easy access for maintenance.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 interrupting 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.Cabinet FeaturesThe 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 main structural uprights of the cabinet are made of 36mm waterproof 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.The 1200 and 1500 models incorporate a separate storage or chiller section with an adjustable shelf.The extra internal height inside the cabinet provides good headroom for use of taller equipment and benefits ease of maintenance. 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 FeaturesThere 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 standard filter sock arrangement, the water then overflows into a twin filter sock section which incorporates a diffused silencer plate to silence any water noise. The Reef Pro aquariums now come with a ClariSea ready sump. With this the filter sock section 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 pre filter water flows Into two large equipment compartments. These chambers can both hold equipment such as skimmers, media reactors, calcium reactors etc. or you can use one chamber as a refugium with caulerpa/cheato.Here again there is flexibility to alternate these sections for those who prefer to skim before or skim after the refugium. The final section is a generous sized return pump compartment which sits beside the integrated water top off reservoir.SpecificationsWater Volumes

The sensor on the DDATO has different light colours and patterns to warn of faults or show its status.
Flashing blue and red LED. The unit has been powered on and it is going through its startup process.
Flashing blue LED. A low water level has been detected and the top up unit is operating the pump to refill with fresh water.
Short intermitting blinking blue LED. The waterlevel is above the failsafe sensor and the unit has been temporarily deactivated. When the water level returns to below the emergncy sensor the unit will return to normal operation. The failsafe sensor can be activated after each top up on nano aquariums, this is normal and no action needs to be taken.
Solid Blue LED. The top up unit is in normal standby mode.
Flashing red LED. Alarm mode has been activated. The unit has detected an issue and or the freshwater reservoir is empty.
A red light on the sensor can indicate one of these things.
The sensor's inbuilt emergency shut-off timer has been activated
When the unit performs its first top-up after being powered on it will store the time taken in its memory. If for any reason the top-up unit is activated for longer than 6 times this the sensor will assume there is a problem or that the freshwater reservoir is empty, shut down and show the red warning light.
Corrective action to set the ATO back into normal operation mode and clear the alarm status, power the unit down from the mains plug socket for a few seconds and then power it back up. The sensor should flash red/blue a few times as it reinitialises and then returns to normal operation mode with a solid blue status light.
The sensor is detecting a fault with the ATO pump.
If the pump cannot run the sensor may go into alarm mode and turn off power to the pump. If this is the situation you will notice that when the top-up activates the pump will not turn on and the status light will immediately show red and not flash blue until time out occurs.
Corrective action:_Disconnect the unit from mains power, check that the connector where the power lead and pump plug-in has not become wet and that the impellor in the pump is clean and free to move.
The freshwater reservoir is empty or the sensor is impaired
No water in the reservoir or microbubbles in the water are causing issues with the sensor detecting the water level. Check that the sensor is not in an area where it is subject to small bubbles, eg near the outlet from a skimmer.
Corrective action: If this has occurred check that the sensor is clean, the impellor in the pump is clean and free to move, the freshwater reservoir is not empty, and there is nothing that could be causing the sump water level to fall unexpectedly.
