Premium Ultra-Clear Glass & Reinforced Construction

The REEF-FRAME 500 features an expansive ultra-clear glass display designed to showcase vibrant corals, fish, and elaborate aquascaping.

All four vertical glass panels and the bottom are constructed using 15mm (0.59") glass.

High-quality euro-silicone bonding and reinforced eurobracing provide excellent structural strength while preserving the aquarium's clean, contemporary appearance.

The approximately 59-inch-long display provides generous space for reef structures, swimming channels, and impressive coral colonies.

Extra-Fortified Cabinet – Black, White & New Classic Oak

The REEF-FRAME 500 includes Red Sea's newly designed marine-spec plywood cabinet, engineered to support the full contour of the aquarium.

Its reinforced construction provides a solid foundation for this large-format aquarium.

Adjustable leveling feet allow precise installation, while stainless steel hinges provide durable access to the sump and equipment.

The cabinet is available in three beautiful finishes.

Black Cabinet

A sophisticated, modern appearance that complements contemporary interiors and creates an elegant contrast with colorful marine livestock.

White Cabinet

A bright, clean finish especially well suited for coastal homes, open-concept living spaces, and lighter interior designs.

Classic Oak Cabinet – New

The new Classic Oak finish introduces the natural warmth and character of wood-inspired styling to the REEF-FRAME lineup.

Its furniture-like appearance makes the aquarium feel integrated into a living space rather than simply positioned on a traditional aquarium stand.

The Oak finish is especially attractive alongside wood floors, neutral furniture, and natural interior materials.

All three cabinet finishes feature the same reinforced marine-spec plywood construction, leveling feet, and stainless steel hardware.

Advanced ReefGate Plumbing

The REEF-FRAME 500 incorporates Red Sea's hydrodynamically designed plumbing system, engineered for efficient circulation and quiet operation.

Enlarged downflow pipes help maintain smooth drainage, while the ReefGate precision valve allows fine adjustments to water flow.

Two curved 25mm return outlets distribute water into the display.

The dual-return configuration supports either single or dual return pumps, giving reefkeepers additional flexibility when designing their aquarium.

The central overflow includes effective surface skimming with removable comb sections for convenient maintenance.

Versatile REEF-SPEC Sump

The included 29.3-gallon REEF-SPEC sump provides generous filtration space.

Features include:

• Adjustable protein skimmer chamber

• Removable mechanical filtration compartment

• Micron filter socks and media cups

• ReefMat-ready filtration design

• Integrated bubble trap

• Optional refugium divider

• Flexible equipment installation space

The removable mechanical filtration compartment allows reefkeepers to upgrade to a compatible ReefMat automatic roller filter.

Fully Customizable Reef System

The non-MAX REEF-FRAME 500 is designed for reefkeepers who prefer to choose their own equipment.
