180 cm Ultra-Clear Display with White Cabinet

• 600 litre display volume: The main aquarium provides substantial room for coral growth, fish movement, rock structures, open sand, and long-term reef development.
• 180 x 65 x 60 cm dimensions: The 70.9 inch length and 65 cm depth give aquarists a broad reef canvas for large aquascapes and multiple coral zones.
• 19 mm glass build: The REEFER 750 G3 is listed with 19 mm front, side, bottom, and back glass.
• Ultra-clear low-iron viewing: The thick glass panels are designed for clean viewing and reduced tint across the large display.

• Bright cabinet presentation: The white cabinet visually lightens the largest REEFER G3 and suits modern rooms, offices, and showroom-style installations.

G3 Water Management for a Long Reef Display

• Optimized circulation architecture: REEFER G3 systems use improved plumbing and flow design to move water more efficiently through the aquarium and sump.
• Quiet downflow inlet: The enlarged rectangular drain inlet helps reduce turbulence and operating noise.
• ReefGate valve control: Fine drain adjustment allows the overflow and sump level to be tuned for quiet stable operation.
• Surface-skimming overflow: The central overflow with removable surface skimmer helps manage surface film and display water clarity.
• Dual return design: The 750 is planned around dual returns, helping distribute return flow across the long aquarium when matched with the proper pumps.
• Clean plumbing layout: Pre-assembled downflow and return plumbing keeps installation more organized and predictable.

High-Capacity Sump and Extension Sump

• Large-reef filtration flexibility: The sump layout can support skimming, automatic mechanical filtration, carbon, reactors, refugium-style planning, dosing, and controller hardware.
• Built for serious reef systems: The 750 gives advanced aquarists the space needed to build a clean, automated, large reef aquarium around their preferred equipment.

White Cabinet with Aluminum Front Supports

• Marine-spec plywood cabinet: The cabinet is designed for aquarium use with moisture-resistant construction, leveling feet, stainless steel hinges, and a clean white finish.
• Front aluminum supports: The long cabinet span is reinforced with front aluminum supports for added structural rigidity.
• Large equipment compartment: The cabinet provides room for the sump, extension sump, dual return planning, dosing containers, probes, power management, and future equipment upgrades.
• Bright large-system look: The white finish softens the visual mass of the 180 cm aquarium and fits well in contemporary interiors.
• Purpose-built stand: The matching cabinet is designed for the tank footprint and loaded system weight.
