Complete Reef-Ready Equipment Package

ReefLED G2 170 Lighting – 2 Included

Two Red Sea ReefLED G2 170 fixtures deliver powerful coral-focused lighting across the display.

ReefBeat connectivity allows customization of lighting intensity, spectrum settings, and daily schedules.

ReefWave 45 Circulation Pumps – 2 Included

Two ReefWave 45 circulation pumps provide broad, customizable cross-flow water movement.

Each pump delivers up to 3,960 GPH, helping maintain water movement around coral colonies and aquascaping while reducing stagnant areas.

ReefRun G2 8000 Return Pump – 1 Included

The efficient DC-powered ReefRun G2 8000 provides adjustable return flow from approximately 1,080 to 2,200 GPH.

ReefBeat integration allows convenient adjustments and coordination with compatible aquarium routines.

ReefMat 1200 Automatic Roller Filter

The included ReefMat 1200 automatically advances its filter fleece to remove suspended waste and debris.

This reduces routine mechanical filtration maintenance while helping maintain clearer aquarium water.

REEFER DC 900 Protein Skimmer

The included REEFER DC 900 removes dissolved organic waste before it breaks down in the aquarium.

Featuring approximately 530 GPH water flow and 235 GPH air flow, it provides high-performance protein skimming and aeration.

Its self-leveling technology helps maintain consistent skimming performance and reduce the risk of excessive skimming.

Integrated Digital Automatic Top-Off

The digital ATO module automatically replaces evaporated freshwater to help maintain consistent aquarium water levels and salinity.

An integrated temperature sensor provides additional monitoring through ReefControl Pro.

Versatile REEF-SPEC Sump

The included 32.5-gallon REEF-SPEC sump offers space for the ReefMat 1200, DC protein skimmer, and additional filtration equipment.

The layout includes an adjustable skimmer chamber, bubble trap, and removable refugium divider.
