The REEFER-S 700 G2+ Deluxe System (White) blends precision engineering with elegant design, delivering a reef-ready solution for modern aquarists. Within Red Sea Aquariums and REEFER series under the premium Aquariums section, this large-format system provides both strength and functionality in a clean, streamlined build.

REEFER-S 700 G2+ Deluxe: Core Package Features

Every REEFER-S 700 G2+ Deluxe System (White) includes technology designed for reliability, integration, and ease of use.

• Ultra-clear, 0.75-inch beveled-edge glass display tank

• Marine-spec laminated cabinet with fortified aluminum super-structure

• Three ReefLED G2 170 fixtures with secure mounting arms

• Professional sump system with refugium-ready design

• Dual return outlets for balanced flow distribution

• Smart ReefATO+ with temperature probe and leak detector

• Slide-out control panel for organized equipment access

Lighting and Circulation in the REEFER-S 700 G2+ Deluxe

The ReefLED G2 170 lights optimize coral coloration through violet, UV, and 470nm blue spectrum channels. Each fixture integrates with ReefBeat for seamless scheduling. ReefWave circulation pumps use patented gyre crossflow technology to generate even, near-silent water movement across diverse aquascapes.

Filtration and Skimmer Compatibility

The REEFER-S 700 sump design accommodates the ReefMat 1200 roller filter for automated mechanical filtration. Its adjustable-height skimmer chamber enhances protein skimmer efficiency, ensuring optimal water quality. Bubble traps further minimize microbubbles returning to the display.

Water Management and Plumbing

The system incorporates dual return outlets and a large overflow box with removable combs for straightforward cleaning. A precision valve ensures controlled flow adjustment, reducing turbulence while maintaining quiet operation. Pre-formed piping with both metric and U.S. fittings enables flexible installation without the need for adhesives.

What’s in the Box

Red Sea list the main components of a REEFER G2+ system as:

• Glass aquarium
• Cabinet, self-assembly
• ReefMat-Ready glass sump with optional Refugium chamber
• Internal piping kit with outlet nozzle
• ReefATO+ system: controller, pump, level and temperature sensor, leak detector, sensor holder, tube holder, silicone tubing and syphon breaker

This is a Deluxe system, so it also carries Red Sea ReefLED G2 fixture(s) and Red Sea’s ReefLED mounting arm(s). Red Sea do not publish a bill of materials for the Deluxe packages, so the count and model for this system are as stated in the description above rather than quoted from a Red Sea document. Confirm with us before ordering if the lighting configuration is what decides the purchase.

What is not in the box, and catches people out:

• The return pump. No REEFER G2+ ships with one. Red Sea’s own recommendation for this model is 2× ReefRun 5500 or 1× ReefRun 7000.
• A reservoir for the top-off water. The ReefATO+ is included; the container it draws from is not.
• The glass extension sump, which Red Sea supply only with the REEFER 900 G2+, S-850 G2+, S-1000 G2+ and PS-950 G2+.
• The ReefATO+ magnetic corner bracket, which is supplied only with the standalone ReefATO+ kit. A REEFER sump takes the sensor holder directly.

Assembly is covered by the graphic manuals packed with the system, in the order they set out.

Setup & Use

Before anything arrives, check the floor. Filled and running, this model weighs about 1,062 kg / 2,342 lb. The flooring directly under it must be rated for that. The glass aquarium alone is about 191 kg / 422 lb. Work out how many people you need to lift it, and make sure everyone lifting is up to it.

Where it goes. The top of the cabinet sits about 86 cm / 34″ from the floor. Leave at least 10 cm / 4″ of clearance behind the system for cable access and air circulation, and about 60 cm / 24″ between one side and the nearest wall or furniture so you can get to the back. Keep the surrounding area waterproof and move anything that water or salt creep would ruin.

Room temperature. Red Sea recommend a stable 22 °C / 72 °F, in a well-ventilated room with moderate light. Not in front of an air-conditioner, not under a heating vent, not in direct sun.

Never move it with water in it. That is Red Sea’s own note and it is there because people try.

Assembly order. Build the cabinet complete with doors and put it in its final position first. The top board and, on some models, other cabinet parts are packed underneath the aquarium, so the tank has to come out of its packaging to get at them. Stand the glass on the Styrofoam from the packaging so the bulkheads on the tank bottom never touch the floor. On models with adjustable legs, level the tank with a spirit level on the glass top and make sure every leg is touching the floor. Align the cabinet doors before the glass sump goes in.

Plumbing. Hand-tighten the pipe joints. No tools.

Filling, in this order. Check every pipe is properly assembled and every flexible tube secured. Install anything that will displace water in the sump first. Open the main flow valve fully, anti-clockwise. Put about 15 cm / 6″ of water into the overflow box and check inside the cabinet for leaks before going further. Then fill the display, watching the sump level as it comes up. As soon as there is about 15 cm / 6″ in the main pump compartment, switch the pump on and stop adding water; switch on the skimmer and anything else that shifts the sump level, then top up to hold that 15 cm / 6″.

Leave the ReefATO+ Auto-Fill switched off until the system is filled to its normal operating level with saltwater.

Do a power-out test. Before you trust the system with livestock, cut the power and watch where the water goes. The sump has to hold the back-siphon without overflowing.

Flow valve. The fine-adjustment valve on the main downpipe sets the water level in the overflow box between the main and bypass pipe intakes. Set correctly it is silent; if you can hear water returning to the sump, the valve needs adjusting.

Filter bags. 225 micron. Keep at least three sets so a clean one always goes straight in.

Overflow box cover. It cuts the noise of the surface skimmer’s waterfall. If you want to mount lighting on the overflow box’s rear wall, break out the marked section of the cover and smooth the edge with a file or sandpaper.

Warranty scope, worth reading before you buy. Red Sea’s 36-month warranty on a REEFER G2+ covers the Aquarium System: aquarium, sump, pipework and cabinet. It explicitly does not cover the ReefATO+ or anything else bundled into a Deluxe or Max offering; those carry their own warranties. Red Sea’s optional two-year extension is available in a fixed list of countries that does not include India.

Warranty & Support

Red Sea’s 36-month warranty on a REEFER G2+ covers the Aquarium System: aquarium, sump, pipework and cabinet. It does not extend to the ReefATO+ or anything else bundled into a Deluxe offering; those carry their own warranties.

Warranty support is handled by us directly. Message our WhatsApp support with your order number and we will diagnose the fault first. Most cases are solved by replacing a single part, so you rarely need to send the whole unit. If the item does need to come back, it ships to our Delhi or Pune warehouse, whichever one served your order, and courier cost in both directions is borne by the customer. Your GST invoice is valid proof of purchase for the claim.

Returns & Replacement

Returns are accepted within 7 days of delivery, provided the item is unused and in its original packaging. Manufacturer-sealed items cannot be returned once the seal is broken, and sale-priced items are not refundable.

If your item arrives defective or damaged, message us on WhatsApp with your order number, or email us if you would rather, and we will replace it. Approved replacements are delivered within 3 to 5 business days. Transit damage is covered by insurance on every shipment. If tracking shows delivered but nothing reached you, tell us within 48 hours, which is the reporting window Indian couriers allow. Damage caused during installation or use is not covered; replacement spares for such cases are chargeable.
