Regarding a few of the questions posed earlier in the thread.
1) the waves are made for the reef tank by what has to be a 50 foot dump bucket apparatus. It fills and every other minute or so dumps over sending a surge over your head down the face of the reef. Calming music is also played in the background synchronized to the wave crashing. You can get behind the scenes upstairs (school groups are already doing this) and see it in action. It was designed by the former Director of the Waikiki Aquarium who is now the top person at the GA Aquarium (forget his name, sorry...but he's mentioned in Sprung's books.
2) the filtering system for the tanks cycles every bit of the water through the skimmers/filters every 90 minutes.
3) the whale sharks were actually trained in Taiwan (where they were captured) to approach a yellow ladle filled with plankton/etc. So, when its lowered into the water, they line up and they dump it out right in front of their mouths. They look like giant vacuum cleaners when they're eating.
4) an interesting tidbit on the reef. The green colored corals (plate) are actually "seeded" with some sort of gelatin-based vitamin enriched substance. You'll notice the tangs love it and are constantly picking at it.
5) the glass is cleaned daily by divers prior to the doors opening. I understand that local divers can sign up to "volunteer" to clean the glass on a rotating basis. There is always a safety diver in with them in case the sharks start getting aggressive...which they say shouldn't happen as they feed them at regular times.
6) the bottom feeders are fed by hand (again by divers)...otherwise all the other fish would eat everything and they would starve.
7) the vast majority of the reef fish were acquired from the Atlanta airport in a sting of illegally smuggled tropical fish last summer.
8) Bernie Marcus, co-founder of The Home Depot donated the $250 million to the GA Aquarium and it opened up on day one debt-free.
All I can say is plan to spend 4-5 hours...I think the planners thought people would be in/out in about 3 hours...not so. Also, check the website and make reservations before you come. Trying to get a ticket at the door may not be possible, especially on weekends.
Last note: after seeing this my wife came home and said our 180-gallon looks really small now. I'm planning on knocking out the main floor and putting my own surge reef tank that will encompass the entire basement as soon as I hit the GA Lottery.

Okay, but maybe I now can move up to the 500 I've had my eye on.
