Premium Ultra-Clear Glass & Reinforced Construction

High-quality euro-silicone bonding and reinforced eurobracing provide structural stability while maintaining a clean, modern appearance.

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

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

Adjustable leveling feet help provide a stable installation, while stainless steel hinges ensure convenient access to equipment.

Choose from three distinctive finishes.

Black Cabinet

A sleek, contemporary finish that draws attention to the colorful aquarium display.

White Cabinet

A clean, bright finish that complements coastal homes and modern interiors.

Classic Oak Cabinet – New

The new Classic Oak finish brings a warm, wood-inspired appearance to the REEF-FRAME collection.

Its natural aesthetic helps the aquarium blend with furniture, wood flooring, and neutral interior finishes while retaining the same durable cabinet construction.

All three finishes share identical structural features and equipment compatibility.

Advanced ReefGate Plumbing

The included ReefGate precision valve allows fine adjustments to water drainage for quiet, consistent operation.

Hydrodynamically designed plumbing and enlarged downflow pipes help maximize circulation efficiency.

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

The central overflow includes removable surface-skimmer comb sections for convenient maintenance.

Complete Reef-Ready Equipment Package

ReefLED G2 115 Lighting – 2 Included

Two ReefLED G2 115 fixtures provide powerful coral-focused lighting across the display.

ReefBeat connectivity allows customizable intensity, color settings, and schedules.

Two compatible mounting arms are included.

ReefWave 25 Circulation Pumps – 2 Included

Two ReefWave 25 pumps provide broad, customizable cross-flow water movement.

Each pump delivers up to 1,980 GPH, helping maintain circulation around rockwork and coral colonies.

ReefRun G2 6000 Return Pump

The DC-powered ReefRun G2 6000 provides adjustable return flow to maintain circulation between the sump and display.

Its variable-speed design allows convenient flow adjustments and efficient operation.

ReefMat 500 Automatic Roller Filter

The ReefMat 500 automatically advances filter fleece to capture and remove suspended waste.

This reduces traditional mechanical filtration maintenance while helping maintain consistent water clarity.

The REEFER DC 600 removes dissolved organic waste from aquarium water.

Its self-leveling technology helps maintain stable skimming performance while reducing the risk of excessive skimming or collection-cup overflow.

Integrated Digital Automatic Top-Off

The included digital ATO module automatically replaces evaporated freshwater and incorporates a water-level and temperature sensor.

This helps maintain consistent salinity and reduces everyday maintenance.

Versatile REEF-SPEC Sump

The included 18.8-gallon sump offers an adjustable skimmer chamber, integrated bubble trap, refugium flexibility, and space for the included filtration equipment.
