Red Sea REEFER 200 G3 Aquarium System (42 Gal)
The Red Sea REEFER 200 G3 is a premium rimless, reef-ready aquarium and cabinet system with a 41.7 gallon display and a 52.8 gallon total volume. It pairs Red Sea's ultra-clear beveled glass with a marine-spec cabinet, a glass sump with pre-glued ReefGate plumbing, and the included ReefATO+ auto top-off. Lighting, skimmer, and circulation are left up to you, so you can build exactly the reef setup you want or step up to the fully equipped REEFER MAX version.
This is a large aquarium system sold for in-store pickup only at our shop. Not in stock? We are glad to bring one in as a special order. Give us a call and we will get it set up for you.
