Marine-Spec Cabinet

Each Reefer MAX Aquarium comes with a Marine-Spec Cabinet perfectly sized for the aquarium. The marine-spec laminated cabinets follow the contour of the glass and are now all fortified and made of plywood. The “floating tank” feature is now reinforced with front aluminum supports on all REEFER 625 G2+ models and larger.


(2x) ReefLED 90 Light Fixture & Mounting Arm

Red Sea’s ReefLED series is the result of years of research into the lighting needs of corals. Uniquely designed with a light intensity and spectrum that is 100% utilized by the corals, ReefLED lights are 100% reef-safe & 100% REEF-SPEC, providing optimal growth, vivid colors, and an elegant gentle shimmer throughout the aquarium.


(2x) ReefWave 45 Gyre Pump (3960 GPH)

ReefWave pumps provide optimal flow for corals in a wide range of aquascapes, regardless of their position in your aquarium. Building on the popular patented Gyre cross-flow technology, ReefWave pumps are a refined pump design offering smart control features, powerful, nearly silent gyre flow, and easy maintenance that fans of gyre pumps will love. Each ReefWave pump can be controlled via the included controller, or you can access your pumps through Red Sea's ReefBeat app.


ReefMat 500 Filter Roller

The ReefMat is the latest in automatic mechanical filtration from Red Sea. The ReefMat comes fully assembled and is designed to hang on the side of the Red Sea Reef-Spec sump. Being one of the only automatic filter rollers out there with app control, the ReefBeat app can alert you if your ReefMat needs maintenance, you’re running out of fleece, or there is an error.


ReeferDC 600 Protein Skimmer

Each Reefer MAX system comes with a perfectly sized Reefer DC Protein Skimmer. With self-leveling technology, a smart controller to connect your skimmer to the ReefBeat app, and a Sicce PSK pump at the heart of the operation, the ReeferDC skimmer is the perfect pairing for the Reefer Aquariums.

You’ll enjoy the small details that Red Sea has worked into this skimmer, like a manual neck cleaner, precision gear regulator to adjust the foam level, and a foam view window to enable you to see exactly where the foam level is in the neck of the skimmer.


ReefRun 5500 DC Return Pump & Controller

Based on the wildly successful and reliable Sicce platform, the Red Sea ReefRun pumps feature a familiar look and feel, but with some big upgrades. In addition to being able to set the daily flow schedule and activate feed modes, you'll also get notifications if your pump is running dry, disconnects, or is otherwise malfunctioning, allowing you to quickly fix the problem and get everything back up and running without missing a beat. 


ReefATO+ Auto Top Off System

Every Reefer Max Series model includes the ReefATO+, an exceptionally reliable and smart auto top-off system. The ReefATO+ is more than just an ATO—it also includes an accurate temperature monitor and external leak detector, coupled with a smart controller that connects to the ReefBeat ecosystem to alert you if anything goes wrong. 


Slide Out Control Panel 60

With Red Sea’s new Slide-Out Control Panels, you can have all your reef monitoring and maintenance devices mounted in a single, easy-to-access location. Affix the panel to the side of your aquarium cabinet and enjoy easy sliding access to your equipment. Constructed from marine-spec laminated plywood and stainless steel.


3+2 Extended Warranty Plans

All REEFER aquariums include a standard 2-year warranty. Register your brand-new Red Sea system within 90 days of the original date of purchase and turn your standard 2-year warranty into 3 years at no extra cost. 1-2 year extended protection plans are also available for purchase through Red Sea's warranty registration page. That's up to 5 years of worry-free protection!


Note: All Red Sea Reefer Aquariums include a black interior finish, regardless of the exterior finish.
