Red Sea REEFER 200 G3 in Black – Bold Design, Smarter Reefing

The REEFER 200 G3 in Black from Red Sea Aquariums and the REFER series turns reef keeping into both a science and an art. You’ll find it in our Aquariums category. This mid-size system delivers a professional-grade foundation with a bold aesthetic that makes a statement in any home or office. The matte-black cabinet adds contrast and depth, while the rimless glass tank showcases coral color and texture in vivid detail.

Precision Built for Everyday Performance

The Red Sea REEFER 200 G3 Aquarium in Black marries modern engineering with subtle sophistication. Its ultra-clear, beveled glass and rimless design keep attention on your aquascape—not the hardware. Meanwhile, the updated ReefGate flow valve lets you fine-tune for quiet operation. You assemble every pipe, joint, and connector without glue, so you click components together, fill, and run.

Balanced Filtration and Future-Ready Design

Red Sea designs the REEFER 200 G3 to grow with your reef. The included glass sump organizes equipment for easy access and pairs cleanly with upgrades like the ReefMat 250 or REEFER DC 300 skimmer. In addition, the layout promotes smooth water movement and tidy cable routing, which reduces maintenance so you spend more time enjoying your reef.

System Highlights:

• 41.7-gallon rimless display with ultra-clear glass

• 11-gallon sump for flexible equipment setup

• Quiet operation via ReefGate flow control

• ReefATO+ system with temperature and leak monitoring

• Marine-spec cabinet in a durable black finish

• Ready to upgrade with ReefMat 250 and the REEFER DC 300 skimmer

Marine-Spec Craftsmanship That Lasts

Every REEFER 200 G3 cabinet uses marine-grade laminated plywood that resists warping and moisture damage. The black finish blends with modern décor and, importantly, hides salt creep and water marks. Stainless hinges and leveling feet boost longevity, and the reinforced frame supports your system with confidence.

Built-In Intelligence for Hassle-Free Stability

The REEFER 200 G3 in Black includes Red Sea’s advanced ReefATO+. This smart top-off system manages evaporation, tracks temperature, and detects leaks. Connect it to the ReefBeat App for real-time updates and alerts while you’re away. A secondary sensor adds an extra safety cutoff, and titanium probes immediately flag water where it shouldn’t be.

Frequently Asked Questions About the REEFER 200 G3 in Black

Can this aquarium handle larger skimmers or a ReefMat?

Yes. The sump footprint fits the ReefMat 250 and the REEFER DC 300 and still leaves room to work.

Is the black cabinet durable in humid environments?

Yes. The marine-grade laminate resists swelling, peeling, and corrosion—even under high humidity.

Does the ReefATO+ require Wi-Fi?

Not strictly. Wi-Fi enables app control and alerts; however, the system continues running once configured.

Can this tank support mixed reefs?

Absolutely. The display volume and sump capacity support soft coral, LPS, and even SPS-dominant builds.

What lighting pairs well?

Many reefers choose the Red Sea ReefLED 90 for balanced PAR and even coverage; alternatively, you can scale to your coral mix.
