Premium Ultra-Clear Glass & Reinforced Construction

The REEFER S-700 G3+ features a stunning ultra-clear glass display designed to showcase vibrant fish, corals, and aquascaping with excellent clarity.

All four vertical glass panels and the bottom are constructed using 19mm (0.75") glass, bonded with high-quality euro-silicone.

Reinforced eurobracing and additional bottom bracing provide structural support for this large-format aquarium.

The aquarium rests on an aluminum-supported cabinet structure with a modern floating appearance, offering both strength and contemporary styling.

Redesigned Hydrodynamic Plumbing

The G3+ platform features refined plumbing designed to deliver efficient water movement between the aquarium and sump.

A high-precision gate valve allows fine adjustments to the overflow, helping achieve quiet, consistent operation.

Two 25mm return outlets distribute water back into the display, and the plumbing supports either single or dual return-pump configurations for additional flexibility.

Complete Reef-Ready Equipment Package

ReefLED G2 170 Lighting – 3 Included

Three Red Sea ReefLED G2 170 fixtures provide powerful, coral-focused lighting across the spacious display.

These ReefBeat-compatible fixtures offer adjustable lighting schedules and color settings to support a wide range of reef aquarium environments.

ReefWave 45 Circulation Pumps – 2 Included

Two ReefWave 45 pumps provide broad, cross-flow water circulation throughout the aquarium.

Each pump delivers up to 3,960 GPH, with customizable flow patterns that help promote water movement around rockwork and corals while reducing stagnant areas.

ReefRun G2 8000 Return Pump – 1 Included

The efficient DC-powered ReefRun G2 8000 provides adjustable return flow from approximately 1,080 to 2,200 GPH.

Integration with ReefBeat allows convenient control of return flow and coordination with compatible aquarium routines.

ReefMat 1200 Automatic Roller Filter

The ReefMat 1200 automatically advances its filter fleece to remove suspended waste and debris from aquarium water.

This reduces the need for frequent manual filter maintenance while helping maintain consistent mechanical filtration and clearer water.

REEFER DC 900 Protein Skimmer

The included REEFER DC 900 efficiently removes dissolved organic waste before it can break down in the aquarium.

Its self-leveling technology helps maintain stable skimming performance and reduces the risk of excessive skimming and collection-cup overflow.

Integrated Digital Automatic Top-Off

The included digital ATO module automatically replaces evaporated water to help maintain a consistent water level and salinity.

An integrated temperature sensor provides additional monitoring through the ReefControl ecosystem.

Convenient Cabinet & Equipment Management

The modern cabinet combines clean styling with practical access to the sump, filtration equipment, and controls.

An included Slide-Out Control Panel 60 provides an organized mounting location for compatible equipment and keeps electronics easily accessible for adjustments and maintenance.
