REEFER™ Specification


Red Sea is expanding their range of REEFER™ systems with 4 new models which still maintain the familiar rimless format and clean lines of the REEFER series. The impressive, 900 liter / 240 gal. REEFER 3XL 900 model offers hobbyists the freedom to create a truly spectacular reef. 200 cm / 79” long, and 65 cm / 25.6” high and wide, the 3XL 900 introduces an enlarged overflow box with dual side-facing return pump outlets and increased surface skimming that provides ideal water circulation in the tanks with flows of up to 10,000 lph / 2600 gph. These new features have also been implemented on the latest version of the XXL 750 V3 giving it a new look and significantly improved flow dynamics. Both of these systems come complete with fittings to attach either a single or dual return pumps.


A unique feature of the 3XL 900 is a split sump system that provides unsurpassed flexibility. The main sump is set for the usual filtration functions with an optional refugium chamber and a dedicated adjustable height skimmer chamber. The sump extension (60 liters/ 16 gal.) can be connected to the main sump and used for additional filtration, as a larger refugium or even as a dedicated frag tank. Alternatively, it can be set up as an independent unit and used as a full-size (83 liters / 22 gal.) RO reservoir or saltwater reservoir for automated water changes.


4 new REEFER™ models, dramatically expanding the range of its premium reef-ready aquariums to include the XL 200, XL 300, XXL 750 V3, & 3XL 900.
