Welcome to the world of REEFER G2, the next generation of Reef-Ready aquarium systems by Ambassadeur Hotel. Building upon the success of the original Red Sea REEFER series, the G2 series introduces a range of new and improved features that will transform your reef tank into a masterpiece. With enhanced water management, fortified cabinets, thicker glass, and customizable sumps, the G2 REEFER aquarium series is designed to be the perfect canvas for creating your dream underwater paradise.

New & Improved Features

The G2 series takes aquarium design to a whole new level. Here are some of the exciting features you can expect:

  • Rimless ultra-clear glass with a beveled-edge design, now even thicker for added durability.
  • Marine-spec laminated cabinets made from extra-fortified plywood, ensuring your tank is supported by the best materials.
  • Dual side-facing return pump outlets for optimal water distribution, resulting in a healthier aquarium ecosystem.
  • A large central overflow box with a surface skimmer, cleverly hidden away to maintain a clean and visually appealing tank.
  • A silent downflow system with an enlarged rectangular inlet, reducing turbulence and creating a serene environment.
  • Assembly-ready piping with extra bulkhead connectors, allowing for customized setups to suit your unique needs.
  • An improved high-precision valve on the downflow pipe, facilitating easier flow regulation for near-silent operation.
  • A professional REEF-SPEC sump, complete with mechanical filtration media compartments, refugium options, and adjustable skimmer chambers.
  • Additional chambers for chillers, controllers, or other equipment, offering flexibility in expanding your aquarium setup.
  • ReefATO+, a smart automatic top-up system that ensures a stable water level without any hassle.

Extra-fortified Glass and Marine-Spec Cabinets

The G2 series boasts rimless aquariums made from ultra-clear glass with a beveled-edge design. With an increased thickness of up to 19mm, these tanks provide unmatched clarity and strength. Accompanying the tanks are newly reinforced cabinets made of plywood, featuring Marine-Spec water-resistant lamination. Designed to follow the contours of the glass, the cabinets provide a sturdy foundation for your aquarium. Larger models, such as the REEFER 625 G2, even come with additional aluminum “floating tank” supports for added security. Moreover, adjustable leveling feet and stainless steel hinges ensure durability and stability for years to come.

Improved Water Management & Plumbing

The G2 REEFER systems introduce a revolutionary water management system. An efficiently designed overflow box, equipped with dual side-facing return pumps, ensures optimal water circulation and surface skimming. The overflow box comes with a lid that conceals plumbing components and removable weir combs, making cleaning a breeze. Water then flows down an enlarged and rectangular inlet to the downflow pipe, reducing turbulence and creating a tranquil environment. Each G2 model includes a high-precision valve on the downflow pipe, enabling simple regulation for fine-tuning the water flow to perfection.

Reef-Ready Sump – Now ReefMat Compatible

The G2 sump, like its predecessor, is designed with perfection in mind. It features a mechanical filtration compartment with micron filter socks and cups, effectively preventing debris and detritus from clogging vital equipment. In a new development, this compartment is now compatible with the ReefMat 500 or 1200, providing even more filtration options without any modifications. The water then flows into an adjustable-height skimmer compartment, ensuring optimal performance for the skimmer or any other filtration components you choose to include. The final stage involves passing through a bubble trap before reaching the chamber where the return pump (not included) can be placed to complete the water circulation.

The Reef-Ready sump system offers additional features such as an optional refugium compartment, perfect for cultivating chaeto or other macroalgae. Additionally, an RO reservoir is included to maintain consistent water levels, salinity, and flow rates throughout the tank for a thriving ecosystem.

3+2 Extended Warranty Plans

We understand the importance of peace of mind when it comes to your aquarium investment. That’s why all REEFER aquariums come with a standard 2-year warranty. And with the new G2 models, you have the option to purchase an additional 1-2 year warranty plan when registering your system online. This means you can enjoy up to 5 years of worry-free protection, ensuring your reef tank remains a source of joy and tranquility for years to come.
