Red Sea Reefer G2+200 Complete System White

• Rimless, drilled display – a 158-litre display volume with a silent internal overflow, so there's no visible overflow box breaking the sightlines.
• Purpose-built 42-litre glass sump – includes a bubble trap chamber and 225-micron filter bags and media cups, sized to sit inside the cabinet footprint.
• Passive automatic top-up – a float valve tops the sump up from a built-in reservoir as water evaporates. It is not the electronic ReefATO+ controller – see Not included.
• Internal plumbing kit included – piping and an outlet nozzle are supplied, sized for the standard drilled overflow.
• Matching white cabinet – ships flat-packed and needs self-assembly; houses the sump and hides the plumbing.
• 200 litres total system volume – display plus sump, the figure that matters for salt mix and dosing calculations.

• Rimless glass aquarium, factory-drilled for the overflow
• White cabinet (flat-packed, self-assembly required)
• Glass sump with bubble trap chamber
• 225-micron filter bags and media cups
• Float valve for passive automatic top-up, plus a top-up reservoir
• Internal piping kit and outlet nozzle

• Protein skimmer
• Return pump
• Lighting
• ReefATO+ electronic top-up controller – the system ships with a basic float valve only
• Salt mix, substrate and livestock

All three current REEFER G2+ sizes share the same rimless build and the same inclusion list – only the footprint, volume and glass thickness change. The step from 170 to 200 buys mostly depth and sump capacity rather than length, which is worth checking against your available wall space before you order.

• Suitable for: reef and marine keepers who want more display and sump volume than the 170 without moving up to the 300's larger footprint, and are sourcing their own return pump, skimmer and lighting.
• Suitable for: anyone upgrading from a rimmed tank who wants rimless sightlines without paying for equipment they already own.
• Not suitable for: buyers who want a single box that includes a skimmer, return pump and lighting at purchase – that's the Reefer MAX range, not this one.
• Not suitable for: anyone who needs the tank ready to fill and run on day one – budget for a return pump, skimmer and light before you commission it.

Red Sea backs the REEFER range with a manufacturer's warranty, provided in addition to your rights under the Australian Consumer Law – ask our team for the current term on this model before you buy. This is a large glass item delivered on a pallet; the cabinet arrives flat-packed and needs assembly, and you should plan for a level, load-rated floor before the tank goes in. A filled 200 holds up to 200 kg of water alone, before the glass, cabinet, sump and substrate are counted – worth checking with a builder if it's going on an elevated floor.

• Red Sea ReefRun G2 6000 DC Pump – a DC return pump from Red Sea's own range; check the flow you need against your plumbing run before choosing a size.
• Red Sea Reefer Skimmer 300 PSK600 – from Red Sea's Reefer skimmer range, sized to your bioload rather than tank volume alone.
• Red Sea ReefLED 90 – a mounting-ready LED fixture from the same generation of hardware.
• Red Sea Reefer ATO Upgrade Kit – upgrades the standard float valve to the electronic ReefATO+ system.
• Red Sea Coral Pro Salt 20kg Refill Box – mixes enough saltwater for a water change plus top-ups on this size system.

Does the REEFER 200 G2+ include a protein skimmer?

No. It ships with the tank, sump and cabinet only. A protein skimmer, return pump and lighting are all sold separately, so you can choose them to suit your stocking plan and budget.

How much bigger is the 200 than the 170?

The display footprint is the same 60 cm length, but the 200 is deeper front-to-back (57.5 cm versus 50 cm) and taller, giving 30 extra litres of display volume and 5 extra litres of sump.

What's the difference between the included float valve and ReefATO+?

The float valve that ships with the system is a passive mechanical device – it opens and closes to keep the sump topped up from the built-in reservoir. Red Sea's ReefATO+ is a separate electronic controller with a temperature sensor and leak detection; it is not included as standard, but can be added with the Reefer ATO Upgrade Kit.

Is the cabinet pre-assembled?

No. The cabinet is flat-packed and needs to be assembled before the tank goes on top of it.

Will my existing return pump and skimmer fit the sump?

Most standard aquarium pumps and skimmers will fit the sump's chambers, but check your pump's flow rating against the 42-litre sump and your skimmer's footprint against the sump chamber dimensions before you buy.
