Reefer 3XL 900 System (240 Gal)

REEFER 3XL 900

Reefer systems have just gotten even larger. With an impressive 240 gallons of total water volume, the Reefer 3XL 900 takes pre-built reef systems to another level. Red Sea Reefer tanks are going to be the best foundation for any reefer that wants create a spectacular reef without having to hunt down the sump, stand, and plumbing.

With the framework of the Reefer 3XL 900 system, you have the freedom to choose the skimmer, lighting system, return pump, media reactors, and other hardware to complete your dream system. This system also features ultra-clear rimless, beveled glass and heavy-duty plywood cabinets with aluminum supports to ensure the longevity of the system.

• 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
• Professional refugium-ready main sump
• Included extension sump (60 liters/ 16 gal) can be used as a frag-tank, refugium, or independant reservoir

Going from the top of the Reefer 3XL system down to the bottom, the first thing you will notice is the crystal clear glass and elegant beveled edges. The second thing you may or may not notice is the slim overflow that houses all the drain and returns plumbing to keep the water a constant level within the display tank. The return nozzle is fully adjustable to direct the flow where you need it, and the dual drain system keeps overflows from happening like a single drain design may encounter. The dual drain design has one main drain that includes a diaphragm valve for easy tuning and adjustments. The other drain is completely open to flow directly down into the sump in the event that the main drain gets clogged. If plumbing is one of the reasons why you have never wanted to install a tank with a sump don’t worry as Red Sea has done all the planning for you and there is no gluing needed to assemble and seal all the plumbing.

Split Sump - Unsurpassed Flexibility

A unique and exciting feature of the 3XL 900 is the split sump system. 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.
