Product Description - REEFER G2+ (900L) (235G)

A Perfect Foundation For Any Thriving Reef Aquarium 

REEFER G2+ offers an optimal setup to create your ideal reef environment. Its advanced features and customizable setup make it a flexible choice for aquarists.

REEFER G2+ offers enhanced water management, advanced cabinet & aquarium fortification, and integrated ReefMat-compatible sumps. Each system includes the ReefATO+ system as standard, with an optional 5-year extended warranty available.

REEFER G2+ SYSTEMS offer a wide range of capacities, from 170L/45gal to 1000L/264gal, ideal for the Red Sea Experience. Incorporating LED lighting, wave pumps, dosers, and filtration devices, the ReefBeat App lets you manage and synchronize the entire eco-system.
Explore Features:

Rimless ultra-clear glass

REEFER G2+ aquariums are rimless, and constructed from ultra-clear, beveled-edge glass with increased thickness of up to 19 mm or 0.75”. 

Extra fortified plywood cabinet

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 bigger.

Dual return pump outlets

All REEFER 350 G2+ models and bigger now have dual side-facing return pump outlets, creating an even better water distribution.

Surface skimmer

The piping is hidden inside a large central overflow box, which has a large surface skimmer with removable comb parts, for easy cleaning.

Silent download system

The enlarged rectangular inlet to the downflow pipe (on models up to REEFER 625) reduces turbulence, making it easier to regulate.

Assembly-ready piping

All pipes are preformed with quick connectors at all joints (no gluing required). Bulkhead connectors suitable for both Metric and USA standard pipes can be purchased separately, allowing you to customize your sump piping.

High precision valve

All models now have a new and improved high precision valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.

Professional REEF-SPEC sump

The professional sump includes a removable mechanical filtration media compartment (with micron filters & filter cups), an optional refugium compartment, an adjustable height skimmer chamber for optimal skimmer performance, and a bubble trap to prevent air bubbles from returning to the aquarium.


The easily removable mechanical filtration compartment allows for a quick Plug & Play installation of the ReefMat 500/1200.


All REEFER G2+ models come with the state-of-the-art ReefATO+, which keeps your water volume and salinity stable, and includes an accurate temperature monitor as well as a highly sensitive leak detector. *Reservoir not included.

Chiller & harder chamber

Most models come with an additional chamber that can be used for a chiller, controllers and other equipment.
