• 705 L total system volume — 568 L display over a 137 L sump, so dosing and bioload capacity scale with the display rather than being squeezed by an undersized sump.
• Pendant-mounted triple ReefLED G2 170 lighting — ceiling-hung rather than arm-mounted, because a peninsula install has no back wall to fix arms to; the included pendant kit spans a 124–152 cm mounting range.
• Twin ReefWave 45 gyre pumps — wide, low-turbulence flow across the display, controlled independently of the return pump.
• ReefRun G2 12000 DC return pump — variable-speed, app-controlled, feeding the plumbed overflow through a silencing ReefGate valve.
• REEFER DC Skimmer 900 and ReefMat 1200 — mechanical and protein export handled from day one, with the filter roller cutting weekly filter-sock changes to occasional roll changes.
• ReefATO+ auto top-off — holds salinity steady between water changes, with built-in temperature monitoring and leak detection.
• Pre-glued sump plumbing — assembly-ready piping, no solvent welding on setup day.

• Peninsula S-700 G2+ display aquarium and matching cabinet
• Sump with pre-glued plumbing and slide-out control panel
• 3 x ReefLED G2 170 lighting with ceiling pendant mounting kit
• 2 x ReefWave 45 gyre circulation pumps
• ReefRun G2 12000 DC return pump and controller
• REEFER DC Skimmer 900
• ReefMat 1200 automatic filter roller
• ReefATO+ auto top-off unit
• Utility basket

• Heater and any temperature controller — sized separately to your room's ambient temperature
• Chiller, for climates or rooms where ambient heat pushes the tank above a safe reef temperature
• Dosing pump system, for two-part or trace element dosing beyond what water changes provide
• RO/DI unit and saltwater mix — the tank ships dry
• Live rock, sand or aquascape, and livestock
• Test kits and a phone or Wi-Fi network for the ReefBeat app

This is the Max package, not the base Peninsula S-700 G2+: the lighting, return pump, gyre flow, skimmer and filter roller are already fitted. A base Peninsula S-700 G2+ ships as the aquarium, cabinet and plumbed sump only, with none of the above equipment — the two are different purchases at very different price points, and it's worth checking which listing you're looking at before comparing prices elsewhere.

A peninsula install needs clearance on at least three sides rather than one back wall, plus the full 165 cm system height and ceiling clearance for the pendant lighting drop and lid access. At 705 L total volume this is a floor-loading item: water alone weighs roughly 705 kg before the glass, cabinet, rock and substrate are added, so the true filled weight is meaningfully higher again. Red Sea does not publish a filled weight figure for this model, so if it's going anywhere other than a slab or a reinforced ground floor, get the floor checked by a builder or engineer before it goes in.

The ReefWave 45 pumps are rated at up to 3,960 GPH (roughly 15,000 L/h) combined at the pump face, in gyre mode across the display — actual in-tank flow depends on rock placement and pump aim, as with any powerhead. Red Sea has not published a head-loss curve for the ReefRun G2 12000 return pump used in this package, so the flow figure printed on Red Sea's own marketing is a best-case, zero-head number; expect noticeably less once it's pushing water up through the drain plumbing and skimmer. Ask us for the manufacturer's curve sheet if you want to plan dosing or turnover around the delivered figure rather than the headline one.

Suited to reefers wanting an island or room-divider reef, viewed from multiple angles, with lighting, flow, skimming and mechanical filtration matched and pre-plumbed rather than assembled component by component — aquascaping needs to look presentable from more than one side. Not the right starting point for a first marine tank — there's no dosing, heating or RO/DI provision, and a 705 L system carries a proportionally larger cycling, dosing and top-up workload than a nano or standard-size reef.

The ReefMat roller reduces mechanical filtration to periodic roll changes rather than weekly sock washing; skimmer cup emptying and gyre pump impeller cleaning remain routine tasks. Budget for ReefMat roll refills and skimmer neck cleaning as the main consumables.

All included electrical equipment is mains-powered — run it through an RCD-protected circuit, and keep drip loops on every cable entering the cabinet and running up to the ceiling pendant mount. The sump's drain plumbing includes a ReefGate valve for silent operation; check it after any plumbing disturbance, as an incorrectly set valve can cause overflow noise or, in a worst case, a sump overflow.

Covered by Red Sea's manufacturer warranty, which applies in addition to your consumer guarantee rights under Australian Consumer Law. This is an oversized, heavy item shipped assembled or part-assembled on a pallet — expect a two-person kerbside or room-of-choice delivery depending on access, and confirm stair or doorway clearance before ordering.

Why is the lighting on a pendant instead of arms?

A peninsula tank has no back wall, so there's nothing for a standard mounting arm to clamp to. The included pendant kit hangs the three ReefLED G2 170 fixtures from the ceiling instead, on a 124–152 cm drop.

What's the difference between the base Peninsula S-700 G2+ and the Max?

A base Peninsula S-700 G2+ is the aquarium, cabinet and plumbed sump only. The Max adds the lighting, return pump, gyre circulation, skimmer and filter roller already fitted — it's a complete running system rather than a tank you still need to equip.

Do I still need a heater?

Yes. Heating isn't included in any Peninsula S-700 G2+ package tier — size a heater or heater pair to 705 L and your room's typical low ambient temperature.

Can the lighting and pumps run without Wi-Fi?

They'll run on their last set programme without a network connection, but scheduling, ramping and remote monitoring through ReefBeat need a Wi-Fi connection.

Is the floor under this tank a concern?

At 705 L total volume, yes — it's worth checking with a builder or engineer, particularly on an upper floor or bearer-and-joist construction. Red Sea doesn't publish a filled weight for this model; the water alone is around 705 kg before cabinet, glass, rock and sand are added.
