Red Sea Reefer tanks are going to be the best foundation for any reefer that wants custom filtration while having an elegant and professional looking reef aquarium with an included sump, stand, and plumbing.

If you have a personal preference for the skimmer you want to run, lighting system, return pump, media reactors, or any other additional hardware the Reefer aquarium system is for you. With ultra-clear rimless, beveled glass and a marine spec cabinet that follows the contour of the tank down to the floor. All of the reefer systems include a proportionate sump, all the necessary plumbing, integrated auto top off system, and reservoir.


Going from the top of the Reefer XXL 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 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 into 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 you put the Clarissa SK-3000 rollermat in the sump without cutting out the filter sock area?
Question by: John Molhoek on Jan 19, 2020, 6:13 PM
Hey there!

Unfortunately it would not, significant modification would need to be made to make it fit.

Take care
