Red Sea's Reefer series of Reef Systems provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium.

The Reefer series is designed for ease of operation while enabling the advanced hobbyist to install an unlimited choice of lighting, filtration, circulation and controllers to create a uniquely customised system.

Every Reefer XL 300 Deluxe comes with 2 x ReefLED 90 lights and mounting arms.
