Red Sea Reefer-G2+ S 550 Complete System – Black – Red Sea

Red Sea Reefer-G2+ S 550 Complete System - Black

The Red Sea Reefer G2+ S 550 Complete System delivers a powerful, polished reef-keeping experience that balances sleek design with real-world functionality. It’s not just another glass box—this setup is a gateway into high-end reefing without the headaches.

Red Sea Reefer S 550 - A Serious Setup for Serious Reefkeepers

This isn’t your average tank kit from a big-box pet store. The Reefer G2+ S 550 means business:

• 118.4 gallons of display tank space—perfect for tangs that like to do laps.

• 145.1 gallons total system volume with an integrated 26.7-gallon sump that handles the behind-the-scenes work like a champ.

• Comes in at a sleek 47.3” L x 26.8” W x 25.6” H, excluding the light.

• Total height sits at 60.2 inches, making it stand tall but not too towering.

• You’ll get 0.75-inch thick glass on every panel—front, side, and bottom. That’s thicker than a waffle at brunch.

No ReefLED, No Problem – It's DLX-Ready

Let’s talk lighting. The S 550 base model skips the included LEDs, but don’t sweat it:

• It’s DLX-ready, which means it’s compatible with two RL G2 170 units (see frequently bought together section below) if you want plug-and-play lighting later.

• Or go full DIY and slap on your favorite AI, Kessil, or Radion rig—reef nerds love the freedom.

Built-in Tech of the Red Sea Reefer S 550 That Makes Maintenance Less of a Chore

Reefing is fun until you're elbow-deep in filter socks. Fortunately, this system cuts the grunt work:

• Integrated WiFi via the ReefBeat app for seamless ecosystem management.

• Bubble trap sponge and dual outlet returns help keep things flowy and clean.

• Filter bag holders for two 225-micron bags come standard.

• ReefATO+ Kit is included—yes, automatic top-off comes built-in, no extra add-ons needed.

Skip the Pumps, Customize Your Flow

Let’s be real—most reefers want to pick their own pumps. Red Sea gets that:

• Main system pump and circulation pump are not included.

• That means you can pick exactly what suits your tank, from DC-powered beasts to budget-friendly options.

Red Sea Reefer S 550 -  Protein Skimmer & ReefMat Status

• Protein skimmer is not included, but you’ve got the real estate and sump space to fit your favorite model.

• It’s ReefMat ready (not included), so if you’re tired of filter socks, the upgrade path is smooth.

Why Reefers Love the Red Sea Reefer S 550:

• Strong build, clean lines, and no weird proprietary parts.

• Room to grow with livestock and gear upgrades.

• Built-in app connectivity—because nobody likes hunting for timers and test kits.

Final Thoughts: Form Meets Function

The Red Sea Reefer G2+ S 550 isn’t trying to win any beauty pageants—although, it probably could. It’s here to do a job and look good doing it. For reefers who want a mid-to-large tank that’s as much about stability and scalability as it is about style, this setup checks every box.

Whether you’re upgrading from a nano or finally pulling the trigger on your dream tank, the S 550 offers a professional-grade reef system that lets you focus on what matters most—growing coral, managing parameters, and watching your fish live their best lives.
