REEFER™ G2 Water Management System

The comprehensive water management system provides the base for excellent water quality. Surface water from all sides of the aquarium is actively fed to the sump through the regulated silent-flow downpipe, while a larger inlet to the downflow pipe reduces turbulence, meaning a quieter flow. Removable surface-skimming combs surround the top of the centrally located overflow box that houses the downpipe. 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 a silent operation.


On entering the sump the water passes through a removable ReefMatready mechanical filtration compartment with 225 micron filter bags and media cups. the sump comes with an adjustable height skimmer chamber* (enabling you to set the water height for optimal skimmer performance). In order to remove any air bubbles that may have escaped from the skimmer, the water passes through a bubble-stripping cascade on its way to the return pump chamber.

REEFER™ G2 Cabinet

The marine-spec laminated cabinet that houses the sump is now extra fortified, made of plywood, and smartly finished with weatherproof, epoxy-painted doors. In keeping with Red Sea's signature design, the cabinets follow the contour of the aquarium glass.

Integrated Automatic Top-Off

To ensure a constant water level in the pump compartment, all REEFER sumps include an integrated automatic freshwater top-off unit, guaranteeing a constant, stable water flow throughout the complete system.
