Plug & Play smart aquarium systems

The premium REEFER MAX series combines the superior infrastructure of the REEFER G2+ with a full REEF-SPEC® package, providing you with everything you need for a thriving reef.

The REEFER MAX systems are available in a huge variety of sizes (170L/45gal –1000L/264gal), with room-divider Peninsula models and premium S models, and include all our smart lighting, filtration and circulation devices, so you can enjoy the full Red Sea ecosystem experience, operate every aspect via your ReefBeat App, and be at ease knowing that all the essential equipment is included, compatible and at the best possible price.

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 downflow 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 performed 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.

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

Uniquely designed with light intensity and spectrum that are 100% utilized by corals, the ReefBeat App-controlled ReefLED provides optimal growth, vivid colors, and an elegant gentle shimmer throughout the aquarium.

The ReefBeat App-controlled ReefWave provides an optimal REEF-SPEC water flow for corals in a wide range of reefscapes, combining a smooth running and energy-efficient sine-wave motor drive with superior vibration damping mounts and dual bearings.

The ReefBeat App-controlled REEFER DC Skimmers include self-leveling technology that prevents over-skimming and prevents full cups from spilling while continuing to aerate the water.

ReefRun DC Pump
The ReefBeat App-controlled ReefRun DC Pumps can be set to a customized daily schedule, and come with 360-degree rotating outlets, inlet flow guides, extra-long power cables with convenient connectors next to the pump, and a 5-year warranty.

A fully automated, ReefBeat App-controlled roller filter that keeps your aquarium water crystal clear, with a unique mat replacement system that allows you to switch rolls with zero hassle.

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

Control panel
Provides easy mounting and access for controllers and other equipment. *The actual color of the cabinet interior and control panel is black.
