Auto Top Off 

• ReefATO+
  The system is shipped with Red Sea’s ReefATO+ unit (combining top-off control, leak detection, and temperature monitoring).
  The sensor includes a backup probe to prevent overfill, and a leak detection sensor that can shut off the pump if a leak is detected.
  The temperature sensor is factory-calibrated to ±0.1 °C accuracy.
  Notifications and control can integrate with Red Sea’s ReefBeat app / ecosystem.

Typically Included (in “Complete System” version)

• Display aquarium with pre-drilled overflow / plumbing

• Aluminum structure + cabinet (black finish, in this case)

• Glass sump (split system) and pre-installed plumbing including downflow piping, valves, return lines

• ReefATO+ auto top-off / monitoring unit

• Slide-out control panel for mounting accessories

• Warranty coverage (3 years base + registration bonus)

Optional Equipment

To complete the system for reef-keeping, you will generally need:

• Lighting / LED fixtures
  Red Sea often sells these separately (or as “DELUXE” or “MAX” versions) — the S-950 typically pairs with multiple ReefLED G2 units.

• Protein skimmer
  A REEFER DC model (e.g., DC 900) is commonly recommended to match sump size and flow.

• Return / circulation pumps / wavemakers / flow devices
  The system provides return plumbing but not always the pumps. You’ll need one or more pumps to drive circulation in the display and return.

• Filter media, reactor(s)
  Media such as activated carbon, GFO, bio-media, or reactors may be added in media cups or compartments in the sump.

• ReefMat / Fleece Roller Filters (optional)
  The sump is compatible with Red Sea’s ReefMat / NanoMat filter rollers if you want mechanical filtration via fleece.

• Heaters, probes, controller / monitoring systems
  Temperature control, pH / ORP / salinity probes, and a reef controller (if desired) will be needed. The slide-out panel helps mount these.

• RO/DI water system, salt mixing station, test kits
  As with any reef setup, you’ll need water-making, mixing, and testing gear.

• Livestock / corals / décor / live rock / substrate / plumbing accessories
  Rock, substrate, corals, fish, as well as hoses, unions, valves, etc.

Strengths of REEFER Peninsula S 950 G3

• High structural integrity: The Euro-braced and reinforced design should handle large volumes and stresses better than rimless designs.

• Split-sump flexibility: The ability to detach or repurpose the extension sump gives you flexibility for frag tanks or separate filtration zones.

• Improved hydrodynamics: The G3 plumbing redesign, with smoother flow, fewer sharp turns, and the ReefGate valve, helps reduce turbulence, noise, and inefficiency.

• Clean aesthetic & multi-side viewing: Being peninsula-style with black framing and ultra-clear glass, it offers a premium look and viewing from multiple angles.

• Integrated monitoring & ATO: Inclusion of ReefATO+ adds safety and convenience out of the box.
