Red Sea REEFER MAX 525 G3 – Complete Smart Reef System

Build a large reef aquarium around one fully integrated ecosystem with the Red Sea REEFER MAX 525 G3.

The REEFER MAX takes Red Sea's third-generation REEFER aquarium platform and equips it with the major lighting, filtration, circulation, return, and monitoring equipment needed to create a premium smart reef system.

With 142.7 gallons of total system volume, a 59-inch display, three ReefLED G2 115 fixtures, dual ReefWave 45 pumps, ReefRun G2 return pump, REEFER DC protein skimmer, ReefMat 1200, and ReefATO+, the MAX 525 G3 arrives as a coordinated system built around Red Sea's ReefBeat ecosystem.

142.7-Gallon REEFER G3 Platform

The 525 G3 provides approximately:

Total System Volume: 142.7 gallons
Display Volume: 111.7 gallons
Sump Volume: 31 gallons
Display: 59.1" L × 23.6" W × 21.7" H
Total Height: 55.9" excluding lighting

The 525 G3 uses 0.59-inch ultra-clear front and side glass and a new Euro-braced design for additional structural strength.

3x ReefLED G2 115 Lighting

The MAX 525 G3 includes three ReefLED G2 115 fixtures, creating a complete lighting system across the 59-inch display.

The G2 platform provides a reef-focused spectrum adjustable from a natural 10,000K reef-white appearance through 23,000K REEF-SPEC Blue, with violet and UV wavelengths and a dedicated moonlight channel.

ReefBeat control provides access to scheduling, acclimation, lunar cycles, cloud effects, and lighting customization.

Dual ReefWave 45 Circulation

Two ReefWave 45 pumps are included to create broad, powerful water movement throughout the aquarium.

The MAX 525 G3 includes 2 × ReefWave 45 pumps, each rated up to approximately 3,960 GPH, providing the circulation needed for demanding mixed and SPS reef systems.

ReefRun G2 6000 Return Pump

The included ReefRun G2 6000 DC return pump provides adjustable return flow of approximately 950–1,700 GPH.

Generation 3 also introduces redesigned hydrodynamic plumbing capable of increased circulation compared with previous REEFER generations, along with the ReefGate precision gate valve for easier and quieter downflow adjustment.

REEFER DC 600 Protein Skimmer

Protein filtration is handled by the included REEFER DC 600 Skimmer.

Its DC platform adds Red Sea's smart Self-Leveling technology, designed to respond to over-skimming conditions and help prevent collection cup overflow while maintaining aeration.

This brings protein skimming into the same smart ecosystem as the rest of the MAX system.

ReefMat 1200 Automatic Fleece Filtration

The ReefMat 1200 automatically advances fleece as debris accumulates, providing continuous mechanical filtration without the constant cleaning associated with traditional filter socks.

ReefBeat integration provides smart monitoring of the filtration system and fleece usage.

ReefATO+ Included

The MAX 525 G3 also includes ReefATO+, combining automatic top-off with temperature monitoring and leak detection.

That helps maintain stable water volume and salinity while adding another layer of monitoring to the aquarium through ReefBeat.

ReefBeat Smart Ecosystem

One of the biggest advantages of buying the MAX package is that the major smart components are designed around a common Red Sea ecosystem.

Compatible equipment can be managed through ReefBeat, bringing lighting, circulation, filtration, return-pump control, skimming, and monitoring together instead of building the system from unrelated equipment platforms.

Fortified Black Cabinet

The G3 cabinet uses marine-spec plywood construction with laminated panels, epoxy-painted doors, stainless-steel hinges, and leveling feet.

On the 525 and larger models, Red Sea adds front aluminum supports to reinforce the cabinet for these larger systems.

This package includes the Black cabinet.
