The choice of REEFERs for your next tank has just increased: we expanded our range of premium reef-ready aquarium systems with four new models: XL 200, XL 300, XXL 750 V3, and our top-of-the-line 3XL 900. All of the new models will be available at the beginning of 2020.

The REEFER XL 200 and XL 300 models give extra room for enhanced aquascaping in the 24”-36” size range. The XL 200 & XL 300 are not only higher and wider than the popular 170 & 250 models, they also feature a laminated, plywood cabinet with adjustable feet.

At the top end of the range, the all-new REEFER 3XL 900 model maintains the familiar rimless format and clean lines of the REEFER series. The impressive 240-gallon REEFER 3XL 900 gives you the freedom to create a truly spectacular reef. Seventy-nine inches long and 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 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 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 (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 (22 gal.) RO reservoir or saltwater reservoir for automated water changes.
