Red Sea REEFER 900 G2+
The REEFER™ 900 allows you to take reefscaping to another dimension. The 3XL 900 is 65cm (25.6″) high & wide, and 200cm (79″) long with a 900 liter (240 gal) capacity. This unit introduces an enlarged overflow box with dual side-facing return pump outlets that provides ideal water circulation in the tanks with flows of up to 10,000 lph/2600gph.
A unique feature of the 3XL 900 is a split sump system that provides unsurpassed flexibility. The main sump is set for the main 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.
