Red Sea Deluxe Reefer aquariums now come with Red Sea ReefLED 90 lighting along with Red Sea's RL90 mounting system all in a single package.


Deluxe Reefer XL 425 Aquariums include 2x Red Sea ReefLED 90 Lights

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 XL 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 return plumbing to keep the water a constant level within the display tank and surface skimming while being super quiet and taking up a very small amount of real estate inside of the tank. The return nozzle is fully adjustable for 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.

The sump includes a filter sock holder and sock to keep large pieces of debris and detritus from clogging pumps and other pieces of equipment. The water can then flow from the filter sock into the skimmer compartment where the water will keep a steady level to aid in the best performance in your choice of skimmer or any other filtration components that you choose to include can be placed there. The water will then flow through the final bubble trap and in to the final chamber where the return pump (not included) can be placed to pump water back through the Reefer tanks return plumbing.

When water starts to evaporate all Reefer systems include an integrated top off system and reservoir that can hold a few days worth of top off water to keep the water level, salinity and flow rates consistent throughout the tank.

Product Questions

Can I purchase the 425XL without the cabinet.? My aquarium cracked & needs replacing
Question by: Sonner L Moore on Dec 28, 2021, 10:16 AM
Unfortunately, we do not carry it like that. You would need to reach out to Red Sea for that.

What are the light mounts dimensions. I need to know for a custom lid
Question by: Tristan on Mar 1, 2018, 9:19 PM
Hi there,
Thank you for reaching out.
The light mounts when put together are 3" wide and would stick into the tank about 1/2"
Please let us know if you have any other questions.
Have a great day!
