The new REEFER™ series have advanced sumps with the following exciting new features:

• An adjustable height skimmer chamber, enabling you to set the water level for optimal skimmer performance.
• A “Refugium Ready” sump with two pre-set positions allows you to decide how much of the sump you want for your skimmer and other reactors and how much as a dedicated refugium chamber.
• Micron filter bags and filter media cups
• RO liter reservoir that can be slid aside when necessary for pump maintenance.

REEFER 3XL 900 – What’s included:

• Rimless, 19mm / ¾” super-clear, beveled edge glass aquarium
• Elegant, reinforced plywood Marine-Spec cabinet with aluminum support
• Dual side-facing return pump outlets with fittings for one or two pumps
• Enlarged overflow box for increased surface skimming
• Unique split sump system for unsurpassed flexibility:
• Professional refugium-ready main sump with variable height skimmer chamber and micron filter bags and media cups
• Extension sump (60 liters/ 16 gal) can be used as a dedicated frag-tank or refugium. Alternatively, it can be disconnected and used as an independent reservoir of 83 liters / 22 gal.
• 4 units of ReefLED 90 lighting with bespoke mounts (Deluxe models only)
• A silent, regulated down-flow system with emergency overflow
• Assembly-ready piping – no gluing required

Unmatched water circulation & surface skimming

Maintaining the familiar rimless format and clean lines of the REEFER series, 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. The new dual return system and the enlarged overflow developed for the 3XL 900 have also been implemented on the XXL 750 V3, giving it a new look and significantly improved flow dynamics and surface skimming. Both systems come complete with fittings to attach either single or dual return pumps.

The new split sump – unsurpassed flexibility

A unique feature of the 3XL 900 is a split sump system that provides unmatched 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 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 RO reservoir or saltwater reservoir for automated water changes.
