I finally did this dive. It was awsome! Just like the posts said, viz was a nice 203' and no current. The staff was very professional and friendly. The equipment provided was perfectly adequate for this dive. Nothing fancy, but not junk. I originally planned for the 4:30 dive, but changed it to the later dive after reading a post here on SB letting me know that I may get a few extra minutes bottom time with the later dive. There were supposed to be only 6 divers, but there were 13! A few missed the earlier dive and were allowed to do the later dive.
We were met promptly at 5:30 and taken to the back of the aquarium for a quick tour. We then went inside and had a brief overview of what to expect and of course, the standard forms needed to be filled out. They issued us shorty wetsuits and booties and then we went topside, above the general admission area, to where we enter the water. The DM's lined us up and assisted us gearing up if needed. Once we were all ready, we simply stepped off the ledge into the tank. We did a 10 minute "follow the leader (DM)" tour and then went off in our buddy teams to explore. My family was in the observation area and a DM videotaped us with me in front of them. Then I had a chance to mess with the diners in the restaurant. This was fun. Everyone was taking our pictures and videotaping us.
There were only 3 sharks in the tank and they were all small. The staff said there are several more sharks, but they are still in the isolation tank, being "trained" to be with divers. They said there was a 400 pound turtle which I didn't see. There were eagle rays, sting rays, a HUGE grouper and more fish than you would normally see on a reef dive. The bottom is covered with three feet of broken shells, so you can't silt up the bottom.
Total bottom time was 40 minutes. I would definately do this again. I recommend anyone doing this dive to call ahead and make your reservation ASAP.
