Yes, that is part of the lighting for their reef tank. I believe it is 20,000 gallons. That is just part of it. I counted over 20 metal halides, my guess each is at least 400 to 1000 watts. The best tank was the whale shark tank. That tank is huge. At least 2 million gallons. I went because Seachem was offering classes for store training. Any store can go to it, but you have to sign up with seachem. Have to be a gold dealer, and they will send you out to learn about their products, and you will get a behind the scene tour of the Georgia Aquarium, two days of classes, tour of seachem labatories, etc. Once you pass their test, then you can become platnium.
