Red Sea REEFER Peninsula G3 DELUXE Aquarium System 350

• 353 L total system volume – a 278 L display over a 75 L sump, so dosing and bioload capacity scale with the display rather than being squeezed by an undersized sump.
• Rimless, three-side viewing – the 350 is the one size in the Peninsula G3 range without Euro-bracing on the display glass, keeping sightlines clear from the front and both ends.
• 2 x ReefLED G2 115 with pendant hanging kit – full-spectrum coral-growth lighting arranged for a peninsula's three-sided viewing angle, run and dimmed from the Red Sea ReefBeat app.
• ReefATO+ auto top-off – holds salinity steady between water changes with built-in temperature monitoring and leak detection.
• Pre-glued sump plumbing with a slide-out control panel – no solvent welding on setup day.
• Aluminium marine-spec cabinet with replaceable marine-plywood panels, in black or white, on adjustable levelling feet.
• 5-year warranty – 3 years standard, extending to 5 years with product registration.

This is the Deluxe package – the aquarium, cabinet, sump and lighting, with the auto top-off fitted. It does not carry the return pump, gyre circulation, skimmer or filter roller that Red Sea fits on a REEFER MAX package; those are a separate, higher tier and a different purchase again.

Allow the full 160 cm system height plus ceiling clearance for the pendant lights and lid removal, and clear access on at least one open end given the three-sided viewing format. Red Sea does not publish an empty or filled weight for this model. As a guide, the 353 L of water alone weighs roughly 353 kg before the glass, cabinet, rock and substrate are added – the true filled weight is meaningfully higher again. If this is going anywhere other than a slab or a reinforced ground floor, get the floor checked by a builder or engineer rather than guessing.

The 350 is the entry point to the Peninsula range – the only size without Euro-bracing, and the one that fits a room where the S-700 or S-950's footprint won't.

Suited to a reefer who wants a genuine three-side-viewable peninsula display – as a room divider or against a half-wall – without the size and floor demands of the S-700 or S-950. Not the right starting point for a first marine tank: there's no return pump, skimming, heating or dosing provision, and a rimless three-sided tank has no wall to hide equipment behind.

The ReefATO+ reservoir needs regular topping up and its float/optical sensor kept clear. Without a filter roller or skimmer fitted, mechanical and protein filtration depend entirely on whichever equipment you add – budget for that maintenance separately.

Included electrical equipment (lighting, ATO pump) is mains-powered – run it through an RCD-protected circuit and keep drip loops on every cable entering the cabinet.

Covered by Red Sea's manufacturer warranty – 3 years standard, extending to 5 years with product registration – which applies in addition to your consumer guarantee rights under Australian Consumer Law. This is an oversized 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.

What's the difference between this and the REEFER MAX Peninsula 350?

This Deluxe package is the aquarium, cabinet, sump and ReefLED lighting only. The MAX tier adds a return pump, gyre circulation pumps, protein skimmer and automatic filter roller already fitted – it's a complete running system rather than a display you still need to equip for flow and filtration.

Does it come with a return pump or skimmer?

No. Both are sold separately on the Deluxe package – only the REEFER MAX tier includes them.

Do I still need a heater?

Yes. Heating isn't included on any Peninsula 350 package tier – size a heater to 353 L and your room's typical low ambient temperature.

Is the floor under this tank a concern?

Worth checking, 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 353 kg before cabinet, glass, rock and sand are added.

Can the lighting run without Wi-Fi?

It will run on its last set programme without a network connection, but scheduling, ramping and remote monitoring through ReefBeat need a Wi-Fi connection.
