Red Sea REEF-FRAME 500 Aquarium System (107 Gal)

Red Sea Reef-Frame 500 Aquarium System (107 Gallon) is Red Sea's new eurobraced reef-ready aquarium and cabinet. It is built from thick ultra-clear glass on a marine-spec plywood cabinet that supports the full footprint of the tank, and it comes with a Reef Spec sump and quiet ReefGate plumbing already in place. Lighting, skimmer, pumps, and controller are left to you, so you can build exactly the reef you want. Want it fully equipped? See the Reef-Frame MAX 500. Prefer a rimless look?

What’s Included

• Reef-Frame 500 aquarium: ultra-clear, eurobraced glass bonded with euro-silicone, with a large overflow box and removable surface-skimmer comb.
• Marine-spec plywood cabinet in your choice of Black, White, or Oak.
• Reef Spec sump: dedicated skimmer chamber with adjustable water height, ReefMat-ready mechanical filtration bay, and a bubble trap. Sump divider option for a dedicated refugium chamber (divider sold separately).
• ReefGate precision gate valve on the downflow for near-silent, adjustable flow.
• Dual 25 mm curved return outlets (single or dual return pump) with hydrodynamic piping.
• 5-year manufacturer warranty (3 years standard + 2 years with registration).

Build Your Own Setup

The Reef-Frame is an equipment-ready platform. The return pump, circulation pumps, protein skimmer, ReefMat, ReefLED lighting, ReefControl controller, and ATO module are not included. The system is ReefMat-ready and ATO-ready, so Red Sea gear drops right in, or you can run your own equipment. Ask our team and we will help you spec lighting and equipment for this tank.

Specifications

Choose Your Cabinet Finish

Pick Black, White, or Oak from the drop-down above. The Reef-Frame cabinet is marine-spec plywood built to support the full footprint of the glass, with adjustable leveling feet and stainless steel hinges. Oak is new with Reef-Frame and is not offered on the REEFER G3. The Oak finish arrives October 15, so it shows as sold out until then. Black and White can be special ordered now.

Recommended Pairings

• Salt mixes: mix up saltwater for your fill and water changes.
• CaribSea Ocean Direct: live marine sand to start the reef.
• Seachem HydroTote: haul RO/DI and saltwater for pickup and top-off.
• Corals: stock your new reef.
• All aquarium systems: compare other reef-ready tanks.

FAQ

What comes with the Reef-Frame 500?
The aquarium, a marine-spec plywood cabinet in your chosen finish, a Reef Spec sump, and the ReefGate plumbing. Lights, skimmer, pumps, ReefMat, controller, and ATO are not included.

How is it different from the REEFER G3?
The REEFER G3 is rimless with a laminated cabinet and includes a ReefATO+. The Reef-Frame is eurobraced with thicker glass on a plywood cabinet, adds an Oak finish, and leaves the ATO as an optional add-on.

How is it different from the Reef-Frame MAX 500?
The MAX version is the same tank and cabinet with Red Sea's full ReefBeat equipment package installed: ReefLED lighting, a REEFER DC skimmer, ReefWave circulation, a ReefRun return pump, ReefMat, and ReefControl Pro with ATO.

Freshwater or saltwater?
It is designed as a reef system. The sump layout is built around a protein skimmer and ReefMat for saltwater use.

How does the warranty work?
Every Reef-Frame includes a 3-year warranty, plus 2 more years when you register your system with Red Sea within 90 days of purchase.
