I have to agree, Ripleys is better than Chattanooga but the Georgia aquarium is the best in my opinion. I put a pic of that skimmer on my facebok cause i took a pic with my phone, it has got to be 2 stories tall! I also took a video on my phone of my 2 year old daughter "calling" the sharks just like she does the dogs at home, "here shark, here shark, clap, clap clap" it was the cutiest thing ever! The reef tank at the georgia aquarium is very nice and large, it still looks to be growing in though. The Ripleys reef tanks were nice and looked well established but not excedingly diverse.
