Deluxe Reefer Deluxe 3XL 900 Aquariums include 4x Red Sea ReefLED 90 Lights & Mounting Arms

Over the past few years Red Sea has a lot of time dedicated to testing and researching LED lighting, and the culmination of those efforts led them to the ReefLED 90. Designed for optimal growth while producing great coloration with a pleasant shimmer effect. Red Sea didn't just stop with great function and form, they integrated the control of the light into the ReefBeat smart aquarium app. The ReefLED 90's built-in WiFi lets you directly connect the light to your smart device to set the daily schedule, color, intensity, and other features. Every Reefer Deluxe Aquarium Kit includes the ReefLED lights along with the appropriate amount of mounting arms. 

Going from the top of the Reefer Deluxe 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.
