Red Sea REEFER 625 G3+ Aquarium System – 131 Gallons

A Premium, Customizable Large-Format Reef Aquarium with Advanced Smart Control

The Red Sea REEFER 625 G3+ combines exceptional aquarium craftsmanship, reinforced construction, and intelligent monitoring technology into a premium reef-ready aquarium system.

Featuring a 131.3-gallon ultra-clear glass display, a 32.5-gallon sump, and Red Sea's ReefControl Pro technology, the REEFER 625 G3+ provides an impressive foundation for reefkeepers who want a large aquarium with the freedom to choose their own equipment.

Its nearly five-foot-long display offers generous aquascaping space for beautiful coral colonies, open swimming areas, and a wide variety of marine livestock.

The G3+ generation introduces redesigned high-flow plumbing, enhanced structural support, and integrated smart water-level management.

Unlike the MAX configuration, the standard REEFER 625 G3+ allows you to customize your lighting, circulation pumps, return pump, protein skimmer, and filtration equipment according to your individual reefkeeping goals.
