• White marine-spec aluminium cabinet — matches the rest of Red Sea's REEFER-S range.
• 19 mm glass on a rimless display — the same tank used across the base, Deluxe and Max tiers of this model.

This is the base Peninsula S-950 G2+, not the Max. If you want lighting, a return pump, gyre circulation and a skimmer already fitted, see our Red Sea REEFER-S Max Peninsula 950 G2+ listing instead — same tank and sump, with the equipment built in and pre-plumbed. This bare tank does not arrive ready to run, and the price reflects that: it's the aquarium platform, not a complete system.

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 lid access and whatever lighting mount you fit later. At 947 L total volume this is a floor-loading item: water alone weighs roughly 947 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.

Suited to reefers who already own lighting, a return pump, circulation pumps and a skimmer from a previous setup and want to move them across, or who want to hand-pick every component rather than take a matched bundle. Not suitable if you want a plug-and-play system with everything fitted — for that, the Max version of this same tank is the better starting point, at a correspondingly higher price.

With no fitted equipment beyond the ATO, ongoing maintenance depends entirely on what you install. The sump's media compartment will take a ReefMat roller or conventional filter socks; budget for whichever consumable your choice of filtration uses.

The ReefATO+ unit is mains-powered — run it through an RCD-protected circuit. Any lighting, pumps or skimmer you add should be sized and wired to the same standard, with drip loops on every cable entering the cabinet.

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.

Does this come with lighting or a return pump?

No. This listing is the bare aquarium, cabinet, sump and ReefATO+ only. Lighting, a return pump, gyre circulation and a skimmer are not included and are sold separately.

What's the difference between this and the Max Peninsula 950 G2+?

The Max is the same 947 L tank, cabinet and sump with lighting, a return pump, gyre circulation, a skimmer and a filter roller already fitted and plumbed. This listing is the tank platform on its own — the two are different purchases at very different price points.

Can I add a ReefMat filter roller later?

Yes. The sump's media compartment is built to accept a ReefMat 1200, but the roller unit itself is sold separately and isn't included here.

Is the floor under this tank a concern?

At 947 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 947 kg before cabinet, glass, rock and sand are added.
