Red Sea REEFER 300 G3+ Aquarium System (65 Gal)
The Red Sea REEFER 300 G3+ is a reef-ready aquarium and cabinet system: a eurobraced, ultra-clear glass reef aquarium, a marine-spec cabinet and a sump with ReefGate plumbing, ready for the lighting and equipment you choose. It holds 65 gallons in the display and 79.3 gallons in total. New for the G3+ generation, it includes the ReefControl Lite Controller and the ReefControl ATO Module.
