Equipment and dry goods ship at their own rate. Free shipping over $399 applies to live corals, fish, inverts and copepods, so this item does not count toward that threshold. Your shipping is calculated at checkout from our configured dry-goods carrier rates.

We ship within the continental US. Alaska needs a shipping quote before you order, and we cannot ship to Hawaii — get in touch first.

Description

The Red Sea REEFER Peninsula 350 G3 is a premium rimless aquarium system built on Red Sea’s third-generation REEFER platform. It ships as a complete, reef-ready foundation, giving you the flexibility to add your own filtration, lighting, and equipment on top of a strong factory base.

Display Tank Volume: 73 Gallons
Glass: Ultra-clear, beveled-edge rimless glass with a low-profile overflow
Cabinet: Marine-spec laminated cabinet, available in black or white
Sump: Glass sump, compatible with Red Sea’s ReefMat fleece rollers and REEFER DC protein skimmers (sold separately)
Plumbing: Ready-to-use, pre-glued plumbing with Red Sea’s ReefGate flow valve for quiet, tunable drains
Included: ReefATO+ auto top-off, temperature monitor, and leak detector, all tied into the ReefBeat app
Warranty: 5-Year Manufacturer Warranty (3 years standard + 2 years upon registration)

The ReefATO+ sensor includes a built-in backup float above the primary sensor to shut the pump down automatically in the event of an overfill, along with a pre-calibrated temperature sensor and a saltwater-resistant leak detector, all monitored through the ReefBeat app.

We are an authorized Red Sea dealer and can order any REEFER G3 configuration directly. See the full official spec sheet on Red Sea’s website.

Shipping & Returns

Equipment and dry goods ship at their own rate. Free shipping over $399 applies to livestock only — corals, fish, inverts and live copepods. The $15 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
