Premium Ultra-Clear Glass & Reinforced Construction

The REEF-FRAME 350 features an impressive ultra-clear glass display designed to showcase vibrant corals, fish, and aquascaping with excellent clarity.

The front, bottom, and rear panels use 12mm (0.47") glass, while the side panels measure 15mm (0.59").

High-quality euro-silicone bonding and reinforced eurobracing provide long-term structural support while maintaining the aquarium's clean, modern appearance.

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

The REEF-FRAME 350 includes a newly designed marine-spec plywood cabinet engineered to support the full contour of the aquarium glass.

The cabinet features adjustable leveling feet and stainless steel hinges, providing both strength and convenient access to equipment.

Three available finishes allow the aquarium to blend with your home's décor.

Black Cabinet

A sleek, sophisticated finish that works especially well in contemporary interiors and highlights the colorful reef display.

White Cabinet

A bright, clean finish ideal for coastal homes, modern living rooms, and lighter color palettes.

Classic Oak Cabinet – New

The new Classic Oak finish brings warm wood-inspired styling to the REEF-FRAME series.

Its furniture-like appearance complements natural flooring, neutral interiors, and rooms where a traditional black or white aquarium cabinet may not be the preferred look.

All three finishes share identical marine-spec plywood construction and reinforced support.

Advanced ReefGate Plumbing

The REEF-FRAME 350 includes Red Sea's hydrodynamically designed plumbing system.

Enlarged downflow pipes promote quiet, efficient drainage, while the ReefGate high-precision valve allows fine adjustments to the overflow.

Two curved 25mm return outlets distribute water into the display and support either single or dual return pumps.

The central overflow incorporates an effective surface skimmer with removable comb sections for convenient cleaning.
