Description
The Red Sea REEFER Peninsula S-950 G3 is the standard build of Red Sea’s third-generation REEFER platform. It arrives as a complete, reef-ready foundation, which means the tank, cabinet, sump, plumbing and top-off are done for you and the filtration, lighting and flow are yours to choose. Its display holds 200 gallons, the sump holds 50, and the whole system carries 250.2 gallons of water on a 78.7 by 26.8 inch footprint.
This is a peninsula build, so the glass is finished on three sides and the overflow and plumbing are carried at one end. It is meant to come off a wall or divide a room, not to sit flat against drywall.

Volumes are the manufacturer’s figures for the system as built. Actual water volume in your room will be lower once rock and sand go in. Total height is measured to the top of the tank with it standing on its cabinet, so measure your ceiling and any shelf above the tank before you order.
Compare every REEFER G3 size side by side if you are still deciding. Footprints, tank heights and total heights on the cabinet, all seventeen chassis on one page.
What comes with the REEFER G3
- Ultra-clear, beveled-edge rimless glass with a low-profile overflow
- Marine-spec laminated cabinet in black or white
- Glass sump, sized to accept Red Sea’s ReefMat fleece rollers and REEFER DC protein skimmers (both sold separately)
- Ready-to-use pre-glued plumbing with the ReefGate flow valve for quiet, tunable drains
- ReefATO+ auto top-off, temperature monitor and leak detector, all reporting to the ReefBeat app
- Eligible original U.S. purchasers can receive five-year warranty coverage by registering an eligible new Red Sea system within 90 days. The warranty is non-transferable.
The ReefATO+ sensor carries a backup float above the primary sensor, so an overfill shuts the pump down on its own, and the leak detector is saltwater-rated rather than a freshwater part pressed into service.
Will it fit, and is it the right size for you
Six and a half feet long, 26.8 inches deep, 200 gallons in the display and 250.2 in the system, finished on three sides. This is the flagship of the peninsula line. It is a centerpiece for a room and it should be sited like one: check the floor loading, the sight lines and the service access on all three sides before anything is ordered.
What goes with the REEFER Peninsula S-950 G3
A lid is the one accessory we tell people to buy at the same time as the tank, not later. Every wrasse, every anthias and most of the tangs worth owning will find the one gap you left open. The one cut for this exact model is the Red Sea mesh lid for the REEFER Peninsula S-950.
- Skimming and mechanical filtration: the sump is cut for the REEFER DC 300, REEFER DC 600, REEFER DC 900 and the ReefMat 250, ReefMat 500, ReefMat 1200. Which size you want depends on how heavily you plan to stock and feed the tank, not only on the water volume, so call us and we will size it against your actual plan rather than a chart.
- Lighting: ReefLED G2 60, ReefLED G2 115, ReefLED G2 170. If you would rather have the lighting fitted and mounted at the factory, look at the REEFER Deluxe build of this same tank instead.
- In-tank flow: ReefWave 25 and ReefWave 45.
- Everything else Red Sea: salt, Reef Foundation, Trace Colors, test kits, dosing and ATO are all in our Red Sea department.
If you are working out the real number before you commit, we wrote up what a saltwater aquarium actually costs with actual figures from builds we have done. And if you want us to handle the whole thing, that is what our aquarium installation and maintenance page covers.
