The REEFER Deluxe 300 G3 Aquarium

Red Sea’s REEFER G3 aquariums use ultra-clear, beveled-edge glass for vibrant, distortion-free viewing. A low-profile black overflow box and hidden plumbing keep the display clean and uncluttered, while the rimless design offers a sleek, modern look that lets your aquascape shine.

Display Tank Dimensions: 35.4"L x 22.6"W x 21.7"H

REEFER Marine-Spec Cabinet

The marine-spec laminated cabinet is made of plywood and precisely follows the contour of the aquarium for a seamless fit. It’s built for strength and moisture resistance, with leveling feet and stainless steel hinges to ensure long-term durability. Stands are available in black or white finishes to complement any space. Reinforced aluminum supports are included for the REEFER 525 models and larger.

(2x) ReefLED G2 Lighting

REEFER MAX G3 aquariums include the ReefLED G2 light(s) with mounting arm(s), delivering optimized reef-safe lighting for vibrant coral growth. The upgraded chipset enhances violet and UV wavelengths, with a boosted 470nm blue channel for richer coloration.

With adjustable color temperature (10,000K - 23,000K) and uniform light distribution, ReefLED G2 minimizes hotspots and spillage. An optional clip-on visor (sold separately) reduces glare for better viewing.

Control lighting effortlessly with the ReefBeat app, featuring pre-set modes, sunrise/sunset effects, lunar cycle moonlight, and coral acclimation mode. The mounting arms securely attach to the aquarium and rotate for easy maintenance.

(2x) ReefWave 25 Gyre Pump (1980 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.

REEFER DC 300 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 REEFER DC skimmer is the perfect pairing for this aquarium.

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 Return Pump & Controller

The ReefRun G2 DC pump delivers efficient and customizable water flow for optimal aquarium performance. Designed for durability and energy efficiency, it ensures reliable circulation while operating quietly.

Easily control and fine-tune flow rates with the ReefBeat app, featuring advanced scheduling, feed mode, and safety alerts. Seamless integration with other Red Sea smart devices creates a fully connected and responsive aquarium system.

ReefATO+ Auto Top Off System

Each REEFER MAX G3 system includes the ReefATO+, combining top off control, temperature monitoring, and leak detection all in one device connected to the ReefBeat App.

• Automatic Top Off: The ReefATO+ sensor features a built-in backup sensor 1" above the primary sensors to automatically shut down the ATO pump in the event of an overfill. With multiple probes built onto the sensor, an indication of actual water level can always be seen on the ReefBeat App.
• Temperature Monitoring: The temperature sensor integrated in the ATO+ sensor has been pre-calibrated to give an accuracy of ±0.1°. If the temperature goes outside the acceptable range, you will be sent a ReefBeat notification.
• Leak Detection: The highly sensitive, Reef-Spec leak detector (with saltwater resistant titanium probes) detects both saltwater and RO/DI water. If a leak is detected, the ATO pump is immediately disabled, and after a few seconds to confirm that the leak persists, the controller sounds an optional audible alarm and sends a notification.

Slide Out Control Panel 25

With Red Sea’s 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.

5 Year Manufacturer Warranty (3 years standard + 2 upon registration)

All REEFER G3 aquariums include a standard 3-year warranty. Register your brand-new Red Sea system within 90 days of the original date of purchase to add 2 years of protection at no extra cost. Please see Red Sea's website for full terms & conditions.
