Reinforced ultra-clear glass

Fortified plywood cabinet

REEFER S G3 aquariums are mounted on marine-spec plywood cabinets with leveling feet, with REEFER S models further reinforced with front aluminum supports.

Pump return outlets

All REEFER models now benefit from hydrodynamically superior pipping for improved water distribution. REEFER S models have dual 25mm diameter return pump outlets, while REEFER 750 and above have 32mm diameter dual outlets. All models with dual outlets can be connected to single or dual return pumps.

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 large downflow pipes reduce turbulence, meaning a quieter flow, and have been redesigned with a rectangular profile, enhancing the circulation.

ReefGate high-precision flow valve

All REEFER S G3s include the new ReefGate, high-precision bespoke gate valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.

Hydrodynamically superior piping

All models come with hydrodynamically superior piping that ensures a powerful flow throughout the system.

Reef Spec sump

The Reef Spec sumps are ReefMat and Refugium-ready, and come with an integrated smart ATO module. The sumps also have an adjustable-height skimmer chamber, removable micron filter bags and media cups, and a bubble trap to prevent air bubbles from returning to the aquarium.

ReefMat-ready

The easily removable mechanical filtration compartment allows for a quick Plug & Play installation of the ReefMat 250/500/1200.

ReefATO module

All models come with the ReefBeat App-controlled ReefATO+ system, which keeps your water volume and salinity stable, and includes an accurate temperature monitor as well as a highly sensitive leak detector.

Chiller & hardware chamber

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