McDonald’s Restaurant With Massive Reef Aquarium


McDonalds' Reef Aquarium

Would you like frags with that? Admittedly, that was a bit cheesy, but the story behind the one liner is actually quite interesting. Las Vegas is home to tons of different reef aquariums, many of which are located in casinos and restaurants that dot the world famous strip. But the aquariums aren’t limited to just the fancy restaurants. Apparently, a McDonald’s in Las Vegas is home to a 1000-gallon reef aquarium system. According to some vague information floating around the web, the Micky D’s reef tank measures 96″L x 36″W x 48″H and uses two ASM protein skimmers for filtration. A pair of Iwaki pumps power the closed look, with another Iwaki serving as the return pump. There is apparently a chiller located in the ceiling about the aquarium and a Korallin calcium reactor providing calcium carbonate to the reef. The reef is full of a healthy mixture of corals and clams, including hammer corals, Zoanthids, and various soft corals.

    Must be one hell of a sump. 96X36X48 only figures up to 718 gallons w/o sand and rock on’s calculator and the same on Still cool though and impressive as far as privately owned builds go. 

    • yeah, i was thinking the same thing. one source said 1000-gallons while another said 718. the guy who said 1000 was supposedly a guy who works or has worked on it. must be a big sump and perhaps the number is just shy of 1000-gallons.
