Red Sea Reefer G2+170 Complete System White

• Rimless, drilled display – a 128-litre display volume with a silent internal overflow, keeping the front glass clear of visible hardware.
• Purpose-built 37-litre glass sump – includes a bubble trap chamber and 225-micron filter bags and media cups, sized to sit inside the cabinet.
• Passive automatic top-up – a float valve tops the sump up from a built-in reservoir; 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.
• White cabinet – ships flat-packed and needs self-assembly; matches a lighter fishroom or living space better than the black option.
• 165 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.

White reflects more light back into the room and shows up algae film or salt creep sooner, which some keepers actually prefer – it forces the wipe-down before it becomes visible on the glass itself.

• Suitable for: reef and marine keepers who want a rimless drilled tank, sump and cabinet as a base, and are sourcing their own return pump, skimmer and lighting.
• Suitable for: brighter rooms or a Scandinavian-style fit-out, where a white cabinet reads as furniture rather than an aquarium stand.
• 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: households where cabinet marks and scuffs from moving equipment would bother you visually – they show more readily on white than black.

Red Sea backs the REEFER G2+ range with a 3-year manufacturer's warranty, extendable to 5 years at no extra cost when you register the tank with Red Sea within the promotion's eligibility window – in addition to your rights under the Australian Consumer Law. 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 170 holds up to 165 kg of water alone, before the glass, cabinet, sump and substrate are counted.

• Red Sea ReefRun G2 4000 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 50 – a compact mounting-ready LED fixture that suits this footprint.
• Red Sea Reefer ATO Upgrade Kit – upgrades the standard float valve to the electronic ReefATO+ system.
• Red Sea Salt 20kg Refill Box – mixes enough saltwater for a water change plus top-ups on this size system.

Does the white cabinet mark or yellow over time?

We don't have manufacturer data on long-term colour stability to publish a claim either way – as with any light-coloured cabinet, keep it out of direct sun and wipe up salt splash promptly.

Does the REEFER 170 G2+ White 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.

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 37-litre sump and your skimmer's footprint against the sump chamber dimensions before you buy.
