Fully featured 75 litre/20 gal, Plug & Play® reef system
The MAX® NANO combines a contemporary, rimless design with state of the art technology.
This fully-featured REEF-SPEC® system provides everything necessary in order to enable you to enjoy the beauty and diversity of your own piece of thriving coral reef, rather than worrying about component selection, suitability and compatibility.
The all new MAX® NANO features the very latest in reef-keeping technology including AI’s Prime HD LED lighting with integrated Wi-Fi control, REEF-SPEC® filtration and circulation systems, an Automatic Top-Off unit and an easy access power center.
Selecting a Red Sea MAX® NANO makes reef-keeping easier than ever before.
Red Sea MAX® True REEF-SPEC® for a successful reef
The Red Sea MAX REEF-SPEC® performance criteria is the result of Red Sea’s years of research into the sustainable growth of all corals, including the most delicate “SPS” corals, in an artificial reef environment. This knowledge, gained over 25 years, forms the basis for the specification of all Red Sea MAX® Aquarium systems designs.
Advanced LED Lighting system with integrated Wi-Fi
The MAX® NANO incorporate the all-new AI Prime HD LED lighting, providing the most up to date LED technology to give superb performance and a remarkably user-friendly interface.
The Prime HD unit offers a full spectrum, 7 color LED configuration giving great color rendition and a multitude of lighting effects.
MAX® NANO ultra-clear glass
The front and two side panels of the MAX® NANO are constructed from 8mm ultra-clear glass with smart beveled edges top and bottom for the ultimate viewing experience.
MAX® NANO Circulation
A European Eco pump provides 950 l/h(240gph) of water flow, circulating the entire water volume 12 times an hour through the filter system. Flow is returned to the aquarium via the discrete multidirectional “eye ball” nozzles that can be adjusted to ensure there are no dead spots within the aquarium, preventing harmful detritus from building up on the corals.
MAX® NANO Rear Sump
The complete filtration system is hidden in the rear sump that is topped by a rotatable screen for easy access. Fed by a unique surface skimmer that directs the water to a bespoke micron filter bag, the rear sump houses a silenced REEF-SPEC® protein skimmer, a 950lph/240gph European ECO circulation pump and 100g of REEF-SPEC® Carbon to keep the water crystal clear.
The MAX® NANO is supplied with a 225 micron bag. 100 micron, fine polishing filter bags are also available.
MAX® NANO Protein Skimmer
The heart of the filtration system is the protein skimmer. The NANO skimmer implements Red Sea’s REEF-SPEC® criteria for SPS corals, passing the entire volume of the aquarium water through the skimmer approximately 3 times per hour and with a 3 to 1 water to air ratio. The NANO skimmer is not affected by the regular fluctuation in the water level of the rear sump due to evaporation and has an adjustable outlet gate to maintain the optimal skimmate consistency which will vary according to actual water conditions. The NANO skimmer runs quietly with a built-in silencer on the air intake and a sponge on the outlet to eliminate the sound of cascading water.
MAX® NANO Media Shelf
The rear sump includes a fixed shelf for media, positioned to guarantee 100% positive water flow. The MAX® NANO is supplied with 100g of Red Sea’s REEF-SPEC® carbon that will keep the aquarium water crystal clear for the first 2 months of operation.
Automatic Top-Off
The MAX® NANO includes an Automatic Top-Off unit with a 1.5 litre/ 3.1 gal freshwater reservoir that is hidden behind the screen above the sump.
The design of the rear sump together with the automatic top-off reservoir makes the MAX® NANO self-sufficient for about 3 days.
Control Unit for skimmer and circulation pumps
The MAX® NANO features a power center with individual on/off switches for the skimmer and circulation pumps enabling easy access for feeding and maintenance.
Rotatable Rear Sump Screen.
A screen above the rear sump keeps all of the equipment out of sight but conveniently rotates out of the way for all regular maintenance and if necessary can be completely removed.
MARINE-SPEC Cabinet
The MAX® NANO is available with an optional marine-spec laminate cabinet fronted with weatherproof epoxy painted doors with convenient push openers as well as soft close stainless steel hinges. The MAX® NANO cabinets are offered with Black or White exteriors.
Java Fern is the most popular type of fern with aquatics hobbyists, and is widespread in tropical Asia. This species varies widely and displays a number of different leaf shapes and sizes. A completely undemanding specimen and a perfect plant for beginners, it grows best when the rhizomes are anchored to rocks or driftwood. Low to moderate light is completely sufficient, although it also grows well under strong lighting. Older leaves can sometimes produce plantlets that can easily be cut away and reattached at another point using a piece of thin fishing line.
Spiderwood, or red bog root, has now become a real classic in aquatics. The many-branched and filigree root pieces originate from rhododendron plants from Asia. In contrast to mangrove wood, they do not stain the water - but are originally very light. However, our roots are pre-watered and usually sink quickly. The filigree leaf structure of the variety 'Trident' looks very harmonious in combination with the finely branched Spiderwood roots. Microsorum pteropus 'Trident' grows rather slowly and, like the main form, is very easy to care for and undemanding.

Red Tiger Lotus is broadly distributed across tropical Africa, where it inhabits various bodies of water, including temporary pools and lakes, and flowing water. It has a bulb for storing nutrients and robust floating leaves. Its most attractive feature is the submersed juvenile leaves that do not reach the surface. Of the two colorways, this red variant is the more popular among aquarists; the green version is hard to find commercially. Tiger Lotus is generally undemanding. Older, larger leaves should always be removed at the base of the bulb.

The all-new REEFER G2 series of Reef-Ready aquarium systems has improved upon the REEF-SPEC infrastructure of the original Red Sea REEFER series. With a new and revamped water management system, extra-fortified plywood cabinets, thicker and rimless glass, refugium-ready & ReefMat-compatible sumps, and extended warranty plans; the G2 REEFER aquarium series is designed to be the perfect canvas for the customized reef tank of your dreams!
New & Improved Features
Rimless ultra-clear, beveled-edge glass with increased thickness
Extra-fortified plywood marine-spec laminated cabinets (with additional aluminum “floating tank” supports on REEFER 625 G2 models and bigger)
Dual side-facing return pump outlets for better water distribution (On REEFER 350 G2 models and bigger)
Large central overflow box to hide piping, with a large surface skimmer with removable weir comb for easy cleaning
Silent downflow system with enlarged rectangular inlet to reduce turbulence
Assembly-ready piping now with extra bulkhead connectors in both Metric and USA sizes for customized setups
New and improved high-precision valve on the downflow pipe for easier flow regulation and near-silent operation
Professional REEF-SPEC sump, including:
Mechanical filtration media compartment complete with micron filters and filter cups
Optional refugium compartment
Adjustable height skimmer chamber
Bubble trap
RO Reservoir
Plug & play ready for ReefMat 500 or 1200 Auto Filter Roller (sold separately)
Additional chamber for chillers, controllers, or other equipment (on most models)
Extra-fortified Glass and Marine-Spec Cabinets
The G2 series of REEFER aquariums are rimless and constructed from ultra-clear, beveled-edge glass with an increased glass thickness of up to 19mm. These strong glass tanks sit atop newly fortified cabinet stands made of plywood and with Marine-Spec, water-resistant lamination. Each cabinet stand follows the contours of the aquarium glass, with the larger REEFER G2 models featuring an additional “floating tank” aluminum support. Adjustable leveling feet & stainless steel hinges ensure a lasting and durable stand for your dream aquarium.
Improved Water Management & Plumbing
Up top, the G2 REEFER systems employ a large overflow box with dual side-facing return pumps for optimal water circulation and increased surface skimming. The overflow box includes a lid which hides plumbing components, as well as easily-removable weir combs for quick cleaning and improved surface skimming. Water then exits from the overflow box and travels down an enlarged and rectangular inlet to the downflow pipe, allowing for reduced turbulence & quieter operation. All G2 models also include a newly improved high precision valve on the downflow pipe, allowing for simple regulation to further tune your flow.
Reef-Ready Sump– Now ReefMat Compatible
As with the previous generation of REEFER, the G2 sump includes a mechanical filtration compartment complete with micron filter sock(s) and filter cup(s) to keep large pieces of debris and detritus from clogging pumps and other pieces of equipment. New to the G2, this chamber can be alternatively used with a ReefMat 500 or 1200-- no modifications required! Water flows from the filtration chamber into the adjustable-height skimmer compartment, where the water will be kept at a steady level to aid in the best performance for your choice of skimmer, or any other filtration components that you choose to include. The water will then flow through the final bubble trap and into a chamber where the return pump (not included) can be placed to pump water back through the Reefer tank's return plumbing.
Addtional features of the Reef-Ready sump system include an optional refugium compartment for growing chaeto or other macroalgae, as well as an RO 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.
3+2 Extended Warranty Plans
All REEFER aquariums have included a standard 2-year warranty. With the new G2 models, you can now purchase an additional 1-2 year warranty plan when registering your new system online. That’s a total of 5 years of worry-free protection!

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.

Red Sea’s REEFER™ series of Reef Systems, provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium.
The REEFER™ series combines a contemporary, rimless, ultra-clear glass aquarium with a stylish cabinet and a comprehensive water management system, including a professional sump with integrated automatic top-up, and Red Sea’s unique silent down-flow system.
Incorporating technologies originally developed for Red Sea’s all-in-one MAX® coral reef systems, the REEFER™ series is designed for ease of operation while enabling the advanced hobbyist to install an unlimited choice of lighting, filtration, circulation and controllers to create a uniquely customized system.
Red Sea REEFER™ Deluxe Concept
The REEFER™ Deluxe incorporates the all-new Hydra 26™ HD LED lighting units with Red Sea’s custome mounting system into the Reefer reef ready systems in a convenient single package.
The Hydra 26™ HD unit provides the most up to date LED technology, offering a full spectrum, 7 color LED configuration giving great color rendition and a multitude of lighting effects. The revolutionary control system dynamically adjusts the power available to each color by utilizing power not being used with other colors, effectively enabling selected channels to be ‘boosted’ to above 100% output. The lighting is fully controllable via the built-in WiFi which is compatible with iOS and Android devices, and with any wifi-enabled Mac or PC.
The custom mounting system attaches firmly onto the rear wall of the tank and can be rotated to the upright position during reefscaping or other tank maintenance.
Features of the Red Sea REEFER™ include:
Rimless, ultra-clear, beveled edge glass aquarium
Elegant marine-spec cabinet
Professional sump with constant height skimmer chamber and micron filter bags
Silent, regulated down-flow system with emergency overflow
Integrated automatic top-up system with reservoir
Assembly-ready piping – no gluing required
REEFER™ Specification
REEFER™ aquariums are constructed from thick, beveled-edge, ultra-clear glass to support their elegant and modern rimless design.
The aquarium sits on a recessed base that “floats” it above the cabinet, which seamlessly follows the contour of the glass.
The marine-spec laminated cabinet that houses the sump, (and in the larger models also includes a dedicated, vented space for chillers) is smartly finished with weatherproof, epoxy-painted doors.
REEFER™ Water Management System
Removable surface-skimming combs surround the top of the centrally located overflow box that houses the downpipe, sump return pipe and the discreet multi-directional “eyeball” return outlet nozzle.
In the event of a blockage in the regulated downpipe, an additional emergency overflow pipe provides an unrestricted free flow of aquarium water directly to the sump.
On entering the sump the water passes through a 200 micron mechanical filter bag, before entering the filtration compartment that maintains a constant water height, making it suitable for all skimmers and other reactors.
In order to remove any air bubbles that may have escaped from the skimmer, the water passes through a bubble-stripping cascade on its way to the return pump chamber.
To ensure a constant water level in the pump compartment, all REEFER™ sumps include an integrated automatic freshwater top-up unit, guaranteeing a constant, stable water flow throughout the complete system.
Supplied as a complete self-assembly kit, all pipe work is ready without the need for any gluing.

Catappa leaves coming from Indian Almond Trees (Terminalia catappa) help to replicate natural environments for Bettas, shrimp and other aquarium inhabitants. When added to an aquarium, they release tannins and other organic compounds which aid in maintaining lower pH and gently tinting water. These conditions mimic habitats with acidic water and abundant leaf litter. As catappa leaves decay, beneficial micro-organisms grow on the leaf surface, creating a natural source of food for shrimp, snails, and newly-hatched fish.
Add 1-2 leaves per 20 liters (5 US gallons). Remove and replace every month or as desired. Catappa leaves may float initially but will sink after 2 - 3 days. To make an extract, boil three grams (approx. two-and-a-half leaves) in 1 liter (1 US quart) of water for ten minutes or until desired color is attained. Let extract cool to aquarium temperature and pour directly into the tank or mix with prepared water for water changes. When first using extract, add gradually over a 2 to 3 days and monitor to ensure pH stays within suitable range for tank inhabitants. Chemical filtration media such as activated carbon can remove compounds provided by Catappa leaves.

The Dual All-In-One Standard by UNS comes as a complete system consisting of an aquarium and integrated filter chamber, which offers sufficient space for creating impressive aquascapes. The three-part filter chamber has space for the corresponding Bio Block filter media, the filter sponge and the reliable water pump.
The UNS All-in-One System offers three models, each designed for specific purposes and room designs.
The Standard model encompasses the most common aquarium sizes, providing ample space for beautiful aquascapes. It is ideal for those interested in a lush freshwater planted aquarium or a vibrant saltwater coral reef. Standard aquariums offer perfect proportions inspired by the Golden Ratio (a principle from art and architecture that defines ideal proportions based on the ratio of 1:1.618), making them suitable for both beginners and experienced aquarists who value aesthetics and functionality.
The center piece of each model is the innovative three-part chamber that enables advanced and efficient water treatment.
Chamber 1The first chamber contains a thick, high-quality, reusable black sponge that acts as a mechanical filter medium. This coarse sponge effectively traps debris such as fish waste and plant debris to prevent it from entering the other chambers or the water pump. It is easy to remove and clean, which simplifies maintenance and ensures trouble-free operation.
Chamber 2The second chamber houses the Ultum Nature Systems Bio Bricks, a newly developed porous ceramic biomaterial used for biological filtration. These Bio Bricks are stackable and make a significant contribution to creating a balanced and healthy underwater ecosystem. In addition, this chamber offers space for further filter media, which can be added or adapted as required.
Chamber 3The third and final chamber houses the water pump, which is the centrepiece of the aquarium. This powerful pump is fully submersible and has an adjustable flow nozzle. With the Sigma pump, the water can be circulated efficiently in the aquarium, whereby the standard and rotating nozzles ensure optimum flow direction and circulation.
The Dual All-In-One Standard Aquarium is characterised by its user-friendly design, including the built-in water level control and the cut-out windows that make it easy to monitor the water level in the camber. This sophisticated system offers a comprehensive solution for aquarium water maintenance, with particular emphasis on efficiency and ease of use.
