Red Sea Reefer S-1000 G3+ - Black Cabinet

Red Sea Reefer S-1000 G3+ - Black Cabinet

The Red Sea Reefer S-1000 G3+ - Black Cabinet is a 1,000 litre (264.2 US gallon) flagship reef-ready aquarium system combining a 795 litre (210 US gallon) eurobraced ultra-clear glass display, a 205 litre (54.2 gallon) combined split-sump filtration system, and a black cabinet built around Red Sea's marine-spec anodized aluminum superstructure. Its 210 cm (82.7 inch) length makes it the largest REEFER-S G3+ model, providing an expansive reefscaping platform for substantial coral colonies, multiple rock structures, and broad swimming areas.

The S-1000 G3+ features 19 mm ultra-clear front glass, perimeter eurobracing with additional bottom reinforcement, dual curved 32 mm return outlets, and the precision ReefGate drainage system. Its professional main sump and multipurpose extension sump provide flexible filtration and reservoir options, while the cabinet includes replaceable exterior panels and a slide-out electronics panel. ReefControl Pro and the ReefControl ATO Module provide automatic freshwater replenishment and connected temperature monitoring. The remaining lighting, return pumps, skimmer, and circulation equipment are selected separately.

Red Sea Reefer S-1000 G3+ Black Flagship Reef Aquarium

• 210 cm (82.7 inch) display length: The extended aquarium provides room for expansive reef structures, separated coral gardens, open channels, and substantial aquascapes that would be difficult to accommodate in smaller systems.
• 795 litre (210 gallon) display volume: The main aquarium provides a large viewing area and the physical space required for carefully planned mature reef colonies and appropriately selected marine fish.
• 68 cm (26.8 inch) front-to-back depth: The generous footprint supports layered rockwork, negative-space aquascaping, open sand areas, and circulation paths behind substantial reef structures.
• 65 cm (25.6 inch) display height: The vertical dimension allows coral placement at different levels and permits more substantial three-dimensional aquascaping arrangements.
• 19 mm (0.75 inch) ultra-clear front glass: The low-iron viewing panel provides clear visibility across the large display while contributing to the system's reinforced glass construction.
• Eurobraced and bottom-braced structure: Perimeter bracing, additional bottom reinforcement, and high-quality euro-silicone provide the structural arrangement specified for the premium REEFER-S format.
• Black aluminum-support cabinet: The marine-spec anodized aluminum superstructure incorporates replaceable black panels, hidden adjustable feet, and a dedicated slide-out equipment control panel.

Marine-Spec Aluminum Cabinet for a Large Reef Installation

The REEFER-S cabinet uses a robust aluminum supporting frame and replaceable exterior panels rather than conventional furniture construction alone. On the S-1000, this provides the support and interior organization required for a large glass aquarium, split-sump filtration, and a substantial selection of compatible equipment.

• Anodized aluminum superstructure: The structural frame supports the large display and is designed for long-term use in the marine aquarium environment.
• Replaceable black exterior panels: The modular cabinet combines a dark presentation with exterior panels that remain separate from the supporting frame.
• Concealed heavy-duty adjustable feet: Leveling adjustments help establish correct aquarium support before the system is filled.
• Slide-out control panel: A designated mounting area provides organized access to compatible controllers, dosing pumps, power equipment, and associated wiring.
• Separate auxiliary equipment compartment: Additional cabinet space is intended for compatible chiller equipment or other accessories, subject to the physical dimensions and ventilation needs of the selected hardware.
• Large-system servicing: Plan equipment placement so that sump components, pumps, plumbing connections, and electronics remain accessible without requiring unnecessary dismantling.

205 Litre Split-Sump System with Multipurpose Extension

The S-1000 G3+ combines a professional main REEF-SPEC sump with a separate glass extension sump. Its published 205 litre (54.2 US gallon) combined sump capacity provides a larger filtration platform than the S-850, while the extension offers the flexibility to expand the circulating sump or operate as an independent reservoir or coral-propagation system.

• 205 litre (54.2 gallon) published combined sump volume: When configured as part of the circulating aquarium system, the main and extension sumps provide substantial filtration capacity.
• Professional main sump: The primary filtration area contains the mechanical filtration section, adjustable protein skimmer chamber, and return circulation equipment.
• Connected filtration extension: The glass extension can be used for additional filtration, a larger refugium, or other compatible water-treatment equipment connected to the main sump.
• Independent freshwater reservoir: When disconnected, the extension can store RO/DI freshwater for the included automatic top-off system.
• Independent saltwater reservoir: A disconnected extension may also be used for prepared saltwater storage in a planned water-change arrangement.
• Dedicated frag-tank option: With appropriate independent equipment, the extension can be used as a coral propagation tank rather than part of the main sump.
• Operating volume consideration: The published 1,000 litre system figure includes the manufacturer's combined sump capacity. Water held in a separately operated reservoir or frag tank does not increase the circulating aquarium volume.
• Optional refugium divider: A compatible divider also allows a dedicated refugium to be arranged within the main sump.

ReefMat-Ready Mechanical Filtration and Adjustable Skimmer Chamber

The professional REEF-SPEC main sump includes removable mechanical filtration and an adjustable skimmer chamber. The S-1000 retains the same general filtration architecture as the S-850 while providing more overall sump capacity for planning compatible equipment.

• Two 225-micron filter bags: The supplied fine-mesh filters collect suspended debris entering from the aquarium overflow and can be removed for cleaning.
• Two filter media cups: The included cups provide alternative mechanical filtration arrangements.
• Removable ReefMat-ready compartment: The filter assembly can be converted for compatible automatic fleece filtration without requiring a redesigned standard drain.
• Optional ReefMat 1200: Red Sea specifies the ReefMat 1200 for the corresponding REEFER-S MAX 1000 G3+ equipment package.
• 21-27 cm adjustable skimmer depth: The main sump's operating level can be set between approximately 8.3 and 10.6 inches to accommodate compatible protein skimmers.
• Additional filtration options: The main sump and extension can be arranged to support compatible media equipment, refugium filtration, or other nutrient-management equipment according to the reef's requirements.
• Equipment fitment: Select a protein skimmer for the actual sump chamber dimensions and water depth rather than relying solely on the aquarium's nominal 1,000 litre system capacity.

Dual 32 mm Returns and ReefGate Flow Management

The REEFER S-1000 G3+ uses two curved 32 mm return outlets to distribute filtered water into the extended display. Its enlarged central overflow, hydrodynamically designed plumbing, and high-precision ReefGate valve are intended to move water efficiently between the aquarium and sump with reduced turbulence and operating noise.

• Dual curved 32 mm (approximately 1.26 inch) returns: The aquarium supports compatible single- or dual-pump plumbing arrangements, with water entering the display through two outlets.
• ReefGate precision drainage: Fine valve adjustment helps balance the overflow water level against the selected return pumps.
• Enlarged rectangular downflow inlet: The redesigned drain entrance reduces turbulence as aquarium water travels into the filtration plumbing.
• Removable surface-skimming combs: The central overflow collects surface water through sections that can be removed for cleaning and maintenance.
• Hydrodynamic plumbing: Factory-designed piping reduces unnecessary flow restrictions between the main display and sump.
• Correct pipe sizing: Both the S-850 and S-1000 G3+ use 32 mm return outlets, unlike the 25 mm returns on the smaller S-550 and S-700.
• Independent in-tank circulation: Wavemakers should be selected separately to provide suitable flow through the 210 cm display; sump return flow alone is not a substitute for carefully planned circulation around coral colonies.

Included ReefControl Pro and Smart Automatic Top-Off

The REEFER S-1000 G3+ includes ReefControl Pro and the ReefControl ATO Module, providing digital top-off and temperature monitoring as standard equipment. The Pro controller also supplies connections for additional compatible sensors and devices, allowing the installation to expand as monitoring needs develop.

• ReefControl Pro Controller: Supports up to seven compatible ReefSense digital probes or sensors and two 12V DC devices.
• Digital top-off system: The ReefControl ATO Module monitors sump water level and operates its DC pump to replace freshwater lost through evaporation.
• Integrated water temperature monitoring: The ATO level sensor contains a digital temperature sensor, allowing readings and notifications through the connected controller.
• Included ATO installation components: The module provides its level sensor, mounting hardware, DC pump, silicone tubing, tube holder, and siphon breaker.
• ReefBeat ecosystem: Compatible monitoring equipment and connected devices can be accessed through Red Sea's ReefBeat platform.
• Optional ReefSense probes: Additional compatible pH, salinity, ORP, and other sensors can be added according to the aquarium's needs.
• Optional ReefControl Power: Compatible power-management hardware can extend the system's control of connected AC equipment.
• Standard versus MAX: The controller and ATO Module are included, but additional water-parameter probes, lighting, circulation pumps, return pumps, and protein skimmer equipment from the MAX package are not.

Planning a Flagship Eight-Foot-Class Reef System

The S-1000 G3+ is designed for substantial marine aquarium installations requiring extensive aquascaping room and a customizable filtration arrangement. Its 210 cm display length, 68 cm width, and configurable split sump make detailed equipment and access planning especially important before the aquarium is assembled.

• Return pump reference: Red Sea specifies two ReefRun G2 12000 pumps for the corresponding MAX S-1000 G3+ configuration. These are sold separately with the standard reef-ready aquarium.
• Lighting reference: The equivalent MAX package uses four ReefLED G2 170 fixtures. Alternative lights should be selected to provide suitable coverage and intensity over the 210 x 68 cm (82.7 x 26.8 inch) footprint.
• Protein skimmer reference: Red Sea pairs the MAX package with an RSK DC 900. Other skimmers should be checked for chamber fitment and the adjustable 21-27 cm (8.3-10.6 inch) water depth.
• Supplementary circulation: The MAX configuration uses two ReefWave 45 pumps. Additional or alternative wavemakers should be planned around rockwork, coral placement, and the long display.
• Split-sump configuration: Decide whether the extension will provide additional filtration, a refugium, freshwater storage, saltwater storage, or independent coral propagation before installing accessories.
• Reef monitoring: Optional ReefSense probes, dosing equipment, and ReefControl Power may be incorporated according to the requirements of the reef.
• Installation planning: Confirm adequate floor support, delivery access, lifting arrangements, and room to service the sump and electronics. The published water volume alone represents approximately 1,000 kg of water before accounting for glass, cabinetry, rockwork, and equipment.
• Compared with the S-850: The S-1000 adds 30 cm (11.8 inches) of display length, 115 litres (30.4 gallons) of display volume, and 35 litres (9.2 gallons) of combined sump capacity while retaining the same front-to-back width and height.
