Red Sea Reefer-S 550 G3 System (118 gal)

**ALLOW 2-4 WEEKS FOR DELIVERY OR PICKUP

Red Sea has been building aquariums for years, delivering high-quality, thoughtfully engineered systems that make reefing easier and more enjoyable. The REEFER G3 series is a top choice for hobbyists who want a premium aquarium with the flexibility to choose their own filtration, lighting, and equipment. Each system offers a strong, reef-ready foundation with smart features and a clean, modern design.

The REEFER S-550 G3 Aquarium

Red Sea's S-Series lineup includes all the features of the standard REEFER G3 aquariums, but with deeper and wider dimensions. All S-Series aquariums also come with eurobracing at the top of the tank for added structural support and peace of mind. The low-profile overflow box has dual side-facing return outlets that can be attached to a single or dual return pump setup.

Display Tank Dimensions: 47.3"L x 26.8"W x 25.6"H

Aluminum Marine-Spec Cabinet

REEFER S-Series tanks start with a robust aluminum structure. The Marine-Spec cabinetry attaches directly to the aluminum structure, giving you both form and function. The adjustable feet allow for perfect leveling on just about any surface, and are hidden by the cabinet exterior for a more elegant look. Stands are available in black or white finishes to complement any space.

Reef-Ready Sump

The main sump is refugium-ready and has an adjustable height skimmer chamber, enabling you to set the water level between 20-28cm (7.9"-11") for optimal skimmer performance. S-850 and S-1000 models also include an extension sump that can be used as a dedicated frag tank, larger refugium, or for extra filtration equipment. Alternatively, the extension sump can be disconnected from the main sump and used as an auto top off reservoir.

The included sump is compatible with a wide range of filtration equipment, including Red Sea’s ReefMat fleece roller filters and REEFER DC protein skimmers, giving you plenty of upgrade options as your system grows (ReefMat and REEFER Protein Skimmer are sold separately).
