Get quick answers to common questions about Red Sea Reefer G3

What is the Red Sea Reefer G3 series?

The Red Sea Reefer G3 series is a range of high-end, reef-ready aquariums designed for saltwater hobbyists who want a balance of advanced features and clean design. These systems are engineered to simplify marine aquarium setup while offering professional-grade components such as ultra-clear glass, integrated sumps, and plug-and-play plumbing.

How is the Reefer G3 different from previous models?

The Reefer G3 introduces several important upgrades over earlier generations. These include sumps that are pre-configured for Red Sea’s ReefMat filter rollers, improved marine-spec cabinets with higher moisture resistance, dual return outlets for better circulation, and enhanced smart integration with devices like the ReefATO+. The front glass is ultra-clear with bevelled edges, offering an unobstructed view of your marine life.

Can the Reefer G3 be used by beginners?

While the Reefer G3 series is designed with advanced reef-keepers in mind, it can be a good choice for dedicated beginners looking to start out with a solid foundation. The system comes pre-plumbed and includes a sump, cabinet, and RO reservoir, making it easier to install than custom setups. However, users should have a basic understanding of saltwater aquarium maintenance before getting started.

What is included with a standard Reefer G3 system?

Each standard Reefer G3 system includes the glass aquarium, a durable cabinet, a sump system with filtration chambers, media cups or filter socks, and a reservoir for an automatic top-off system. The Deluxe versions also include Red Sea’s ReefLED lighting and mounting arms. The system is designed to be modular, allowing for easy addition of lighting, pumps, and controllers.

What sizes are available in the Reefer G3 collection?

The Red Sea Reefer G3 collection spans a wide range of sizes, starting from more compact models like the Reefer 170 G3 and scaling up to larger options such as the Reefer 625 G3 and Reefer 750 G3. Each model is proportionally designed with an appropriate cabinet and sump to suit different types of marine systems, whether focused on fish, soft corals, or demanding SPS reefs.

Is the Reefer G3 compatible with other Red Sea equipment?

Yes. The Reefer G3 series is built to work seamlessly with Red Sea’s ecosystem of marine aquarium equipment. This includes compatibility with ReefATO+ for automated top-up and temperature monitoring, the ReefMat automatic filter roller, ReefWave circulation pumps, and ReefLED lighting. These components can be integrated using the ReefBeat app for smart control.

What livestock can be kept in a Reefer G3 system?

The Reefer G3 series supports a wide variety of saltwater livestock. These aquariums are suitable for mixed coral reefs, soft corals, LPS, SPS, and fish-only marine tanks. Fish such as tangs, clownfish, gobies, wrasses, and angelfish can be kept in these systems, along with invertebrates like shrimp, snails, and hermit crabs. The built-in sump and strong flow systems help maintain water quality for sensitive species.

How quiet is the Reefer G3 during operation?

The Reefer G3 features a refined downflow system and a quiet return chamber that work together to keep noise levels low. With a suitable DC pump and skimmer, the system is quiet enough for living rooms, offices, or other noise-sensitive spaces. The plumbing is designed for smooth water movement, helping to reduce gurgling and vibration.

What kind of warranty comes with the Red Sea Reefer G3?

All Red Sea Reefer G3 aquariums come with a three-year standard warranty that covers the tank, cabinet, and included plumbing. Customers who register their aquarium with Red Sea receive an extended two-year warranty, bringing the total to five years. This warranty is supported directly by Red Sea and applies to purchases through authorised retailers like Charterhouse Aquatics.
