Effortless Setup with Complete Reef Control of the REEFER MAX S-850 G3

You can explore these components under Filtration & Skimmers and Lighting & Flow Equipment in their respective categories, along with other compatible gear in the REEFER series.

Smart Lighting for Vibrant Coral Growth

The ReefLED G2 170 units produce rich spectrum lighting from 10,000K to 23,000K, with enhanced violet and UV output. The 470nm blue channel brings out coral fluorescence, while built-in sunrise, sunset, and lunar cycles create natural daily rhythms—all adjustable through ReefBeat.

Precision Flow and Filtration

The ReefWave 45 Gyre Pumps move up to 3,960 GPH each, delivering even water flow that mimics ocean currents. The ReefMat 1200 ensures mechanical filtration stays automated, notifying you through the app when the fleece roll nears replacement. Together, they keep the tank stable, clean, and effortless to maintain.

ReefATO+ and ReefRun Integration

The ReefATO+ system maintains salinity and temperature automatically, protecting corals from fluctuations. Meanwhile, the ReefRun G2 DC Pump quietly powers the return system, customizable through the app with feed modes, safety alerts, and scheduled flow variations.
