Red Sea has been building aquariums for years, delivering high-quality, thoughtfully engineered systems that make reefing easier and more enjoyable. The REEFER G3 series is a top choice for hobbyists who want a premium rimless aquarium with the flexibility to choose their own filtration, lighting, and equipment. Each system offers a strong, reef-ready foundation with smart features and a clean, modern design.
The REEFER 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.
Reef-Ready Sump
The included glass sump features a clean, straightforward layout that makes it easy to set up and maintain. Its flexible design is compatible with a wide range of filtration equipment, including Red Sea’s ReefMat fleece roller filters and REEFER DC protein skimmers, giving you plenty of upgrade options as your system grows (ReefMat and REEFER Protein Skimmer are sold separately).

Ready-to-Use Plumbing
REEFER G3 systems include all the plumbing you need, ready for quick assembly with no gluing required. The redesigned G3 layout reduces the number of 90-degree turns for smoother flow, while the new ReefGate flow valve makes it easy to fine-tune your system's drain plumbing so that it runs quietly.
ReefATO+ Auto Top Off System
Each REEFER 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.

What are our aquariums made of?
Our aquariums are made out of high-quality CAST acrylic. We calculate PSI pressure inside every aquarium to determine the required acrylic thickness to ensure each aquarium is built up to code with no possible risk of failure due to the possibility of it being underbuilt.
What sizes do our aquariums come in?
We offer many different shapes and sizes ranging from 50 gallons to 1,000 gallons. If you do not see a size or shape you are looking for, submit a custom request. We can accommodate just about any size!
Can I customize my aquarium?
Absolutely! Browse our standard sizes and you can easily customize your aquarium build with the click of a button. If you do not see your desired size or shape, submit a custom request and a team member will be in touch with you soon. If you have any questions, please contact us for more information.
Do our aquariums come with any accessories?
Our aquariums are sold alone, without any accessories. If an overflow was included in your purchase, we will provide all dry plumbing (PVC pipes, Durso silencer, bulkhead fittings, lock line, return nozzle) You do have the option to add a stand and/or canopy as well as filter sump and drip tray to your purchase.
Do you offer free shipping?
Yes, we offer free shipping standard LTL shipping on all of our aquariums within the continental United States. If you are overseas, we can ship for free to the local freight forwarding company of your choosing.
How do I clean my aquarium?
We recommend using a soft cotton rag or a micro fiber towel to clean the outside of your acrylic aquarium. You should NEVER use cleaners that contain alcohol or ammonia as this could damage the acrylic and cause crazing. To clean the inside of your acrylic aquarium, we recommend using an ACRYLIC SAFE algae scrubber or pad, ACRYLIC SAFE plastic scraper. It is imperative that you do not stir up sand particles while cleaning the inside of your tank, as this could result in scratching.
What are the benefits of an acrylic tank compared to a glass tank?
An acrylic aquarium will provide the best view of the habitat in your aquarium. Acrylic is approximately 90% more transparent than glass. Acrylic aquariums are significantly stronger than glass aquariums. Glass aquariums are assembled with silicone which dries out and becomes brittle over time. A glass aquarium will eventually always fail. Acrylic aquariums are chemically bonded which can last a lifetime. Acrylic aquariums are more impact resistance. Glass aquariums have sharp edges whereas the edges of an acrylic aquarium are rounded over, sanded and polished to create a smooth edge. Acrylic aquariums are very versatile. You can modify them easily. Acrylic aquariums can scratch easier than a glass aquarium, however scratches can be easily removed with simple kits available online. If you scratch a glass aquarium, it cannot be removed. Acrylic aquariums are half the weight of a glass aquarium. This allows for installation and/or moving of the aquarium much easier. Acrylic aquariums are widely used in just about all aquariums, zoos, educational facilities, universities for their exhibits and research vessels.
What type of filtration system should I use for my aquarium?
The type of filtration system you use will depend on the size and type of aquarium you have. We recommend consulting with an aquarium professional or doing your research to determine the best filtration system for your specific needs.
What types of fish can I keep in my aquarium?
The types of fish you can keep in your aquarium will depend on the size of your aquarium, the water parameters, and the compatibility of the fish. We recommend researching the specific needs and behaviors of each fish species before adding them to your aquarium.
How often should I do a water change?
We recommend performing partial water changes and cleaning your aquarium on a regular basis, typically once a month. However, the frequency of cleaning will depend on the size of your aquarium and the number of fish and other aquatic life you have.
Do you offer any warranty or guarantee on your aquariums?
Yes, we offer a warranty on all of our aquariums. Please see our product listings for specific warranty information.
