Red Sea REEFER G3 DELUXE Aquarium System 200

• 200 L total, on a 59.9 × 57.4 cm footprint – a 158 L rimless display over a 42 L sump.
• 1 × ReefLED G2 115 fixture and mounting arm included – 115 W, roughly 500 PAR at the surface falling to around 150 PAR at 50 cm, tunable white spectrum, rated to 60 cm maximum water depth.
• ReefATO+ built in – automatic top-off with a titanium water-level sensor, integrated thermometer and leak detection, standard on every G3 model.
• Redesigned G3 sump – REEF-SPEC, ReefMat-ready, with a dedicated skimmer chamber and a bubble-trap labyrinth ahead of the pump draw.
• Rimless, ultra-clear glass – beveled-edge front panel for a clean, frame-free view.
• Pre-glued sump plumbing – the downpipe, return line and ReefGate flow valve arrive assembled; no gluing on setup.

• REEFER G3 200 rimless display aquarium
• Marine-spec cabinet in your choice of black or white
• REEF-SPEC glass sump with pre-glued plumbing and ReefGate flow valve
• 1 × ReefLED G2 115 LED fixture with mounting arm
• ReefATO+ automatic top-off system, with water-level sensor, thermometer and leak detector
• Mechanical filtration media (filter socks and media cups)

Not included: return pump, protein skimmer, heater, the ReefMat fleece filter itself (the sump is only pre-fitted to accept one), any additional controller hub, and aquascaping rock, sand or livestock.

All four current REEFER G3 sizes share the same sump architecture, ReefGate valve and ReefATO+ system – the differences are footprint, volume, and how many ReefLED G2 115 fixtures the Deluxe package includes.

Against the 170, the 200 trades nothing in floor length – both are 59.9 cm – for 7.4 cm more depth and 34 L more total volume, at a modest premium. Against the 250, the 200 is 30 cm shorter but holds a similar sump; the 250 is the pick once you have the wall length to spare and want meaningfully more display width rather than depth.

Suitable for: a keeper with a fixed floor footprint length who wants more depth and water volume than the entry-level 170, without stepping up to a longer tank.

Not suitable for: anyone expecting a plug-and-play kit – a return pump and, if wanted, a skimmer or ReefMat still need to be sourced separately.

Rinse or replace the sump's micron filter socks weekly, more often while cycling. Keep the ReefLED's fan intake free of salt dust. Wipe the ReefATO+ sensor periodically to prevent salt creep causing false top-off readings.

Run the ReefLED, ATO pump and any added equipment on 240 V AU-approved supplies with an RCD, with mains connections above the water line and a drip loop. At 315 kg filled with water alone, before rock and sand, confirm your stand or floor is rated for the load at this footprint.

• Red Sea ReefRun G2 4000 DC Pump or Red Sea ReefRun G2 6000 DC Pump – return pump options for a 200-class sump.
• Red Sea Reefer DC Skimmer 300 – sized for the 200's skimmer chamber.
• Red Sea ReefMat Filter 250 – drops into the ReefMat-ready sump chamber.
• Red Sea ReefLED 90/G2 115 Universal Mounting Arm – for a second fixture across the wider 57.4 cm span.
• Red Sea Coral Pro Salt, 20 kg refill – for the initial fill and ongoing water changes.
• Red Sea Seawater Refractometer – check salinity before any new mix goes in.

Red Sea covers the aquarium and cabinet for 36 months from purchase, extendable to 5 years total at no cost if you register within 90 days – Australia is an eligible market. The extension covers the structural integrity of the glass and cabinet only; the ReefLED and ReefATO+ carry their own 24-month manufacturer warranty. These terms sit in addition to your rights under the Australian Consumer Law, which are not limited or excluded by them. As a large glass and cabinet item, this ships as a freight delivery – confirm access and unloading arrangements with us before ordering.

How much more water does the 200 hold than the 170?

34 L more in total – 200 L against 165 L – from 7.4 cm of extra depth on the same 59.9 cm footprint length.

Does the REEFER G3 Deluxe 200 include a return pump?

No. Red Sea's own operation manual only recommends a pump for this sump size; the ReefRun G2 4000 or 6000 DC pumps are sold separately.

Is the auto top-off included?

Yes. ReefATO+ ships standard on every REEFER G3 model, including this one. You'll need your own top-up water reservoir for it to draw from.

What's not included that I'll need before adding livestock?

A return pump, a heater, and ideally a protein skimmer – none of these ship with any REEFER G3 package, Deluxe or standard.

Can this take two lights instead of one?

Yes – the 57.4 cm width comfortably supports a second ReefLED G2 115 on its own mounting arm for more even coverage, though the single included fixture is rated to cover the tank on its own.
