This tank was added in 2007 and is a massively impressive structure that now greets visitors as soon as they pay their entrance fee and walk around the corner from the ticket booth. There is a large lobby with lots of space for catered events, and the 120,000 gallon tank is at such an acute angle that a line of metal "balls" have been drilled into the ground so that visitors will stop before crashing their heads against the huge acrylic panels.
