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

Is this a complete system?
Yes. The MAX package includes the tank, cabinet, sump, plumbing, ReefLED lighting, DC skimmer, ReefWave circulation, ReefRun return pump, ReefMat filter roller, and ReefControl Pro with ATO and a pH/temperature probe. Add salt, sand, rock, and livestock and you are reefing.

How is it different from the REEFER MAX 250 G3?
The REEFER MAX G3 is rimless on a laminated cabinet and uses a ReefATO+. The Reef-Frame MAX is eurobraced with thicker glass on a plywood cabinet, adds an Oak finish, and steps up to the ReefControl Pro controller with pH and temperature monitoring.

Freshwater or saltwater?
Saltwater and reef only. The skimmer and ReefMat are built for marine systems.

What are the display dimensions?
The display tank is 35.4 in x 20.1 in x 20.9 in (53.9 gallons), and the total system stands 53.9 in tall, not counting the light.

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.
