From lighting to filtration and stunning looks-- the Red Sea MAX NANO all in one aquarium series has a great recipe for success, allowing you to have your own piece of the ocean right in your living room. 

Red Sea is constantly innovating and keeping up with current technology in the aquarium market and reefkeeping hobby. The MAX Nano AIO tanks now include LED lighting along with a full filtration system, in addition to circulation and return pumps. The ultra-clear glass lets you see your fish and corals' true colors in a sophisticated rimless design that will instantly bring life and elegance to any room.


Max NANO Complete includes 1x Red Sea ReefLED 50 Light

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 50. 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 50'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. 


Pump Power Center

Max Nano has an integrated power switch box to which circulation pumps and the protein skimmer can be connected for easy on/off control, making them a true all-in-one aquarium system.



Every MAX tank comes with a stand made for saltwater aquariums with marine-spec laminate cabinet, weatherproof epoxy painted doors, push open latches, and soft close stainless steel hinges. Stands are available in two exterior colors (black or white) where the interior will be black on both stand color options allowing for a cleaner overall appearance over time.


Ultra Clear Glass

Standard glass can "wash" out colors because of a small percentage of iron in all glass making it have a slight yellowing appearance. Red Sea uses an Ultra Clear beveled edge glass that has a low iron content allowing you to see the true color of your fish and coral without having any color distortion. The 8mm thick front glass lets Red Sea produce a rimless tank without the need for any ugly bracing.


Filtration and Circulation

Proven Multi-stage filtration lets you keep even the most delicate corals and fish. The included return pump is hidden in the filtration compartment keeping the display portion looking clean and elegant. The built-in filtration also includes a Reef-Spec Nano skimmer, media towers, extra space for additional filters and provisions to add a chiller too.

RS Nano skimmers have a 3:1 water to air ratio creating the perfect skimming conditions within the body of the skimmer. With the advanced design of the protein skimmer, it will not be affected by water fluctuations due to evaporation and has an adjustable outlet gate creating the perfect skimmate consistency for the water conditions.

Product Questions

Can the tank be used without the stand? Can they be purchased separately?
Question by: David Peterson on Dec 1, 2021, 8:26 AM

Thank you for the question. You can use this aquarium with any other stand or table that can support the weight, but unfortunately it is not available for purchase separately. Happy Reef Keeping.

Does this tank have a lid / top? Or one that can be purchased as an accessory?
Question by: Nicole on Apr 3, 2020, 8:30 AM
Hi Nicole,

The Red Sea Max Nano does not include a screen top but there are a few options for screen tops available at BRS.
The first would be the Red Sea brand option - R42080 24" x 24" https://www.bulkreefsupply.com/customizable-diy-aquarium-net-cover-kit-red-sea.html
We also have BRS branded screen top kits available in 1/4" and 1/8" mesh. You will want the 24" rimless kit.

If you were looking for a solid glass or polycarbonate top there are custom and DIY options out there but I am afraid we do not offer any.

I hope this helps!

Where do you put the heater?
Question by: stephen leung on Dec 10, 2018, 6:28 PM
Thanks for the question! Almost all reefers with this tank will put the heater in one of the rear chambers of the tank. Check out our YouTube video about setting up the exact Max Nano system from start to finish! :)
Answer by: Randy on Dec 12, 2018, 11:44 AM
I have been a bulk reef supply viewer for years I've watched tons of youtube videos my uncle and father are hobbiest I'm looking to start my own tank at a cheap price and the reef store I usually go to recommends Red Sea products as one of the best I believe in quality and you get what you pay for. My question is what comes included with the tank? Pumps? Lights? Sump setup? Skimmer? Heater? Temp Gauge? Salinity Tester? Algae Magnet? Return Pump? Thank you and I hopefully wish to purchase this tank!
Question by: Kyle on Jan 21, 2017, 10:13 AM
Great question! This tank is an All In One (AIO) that houses the filtration and return pump in the rear chambers.This includes those pumps, skimmer, the tank and stand, and the light fixture only. All other equipment would have to be purchased separately. :-)
