California Academy of Sciences in Golden Gate Park announced it is constructing what will be the deepest coral reef display in the world.

At 25 feet deep at its max, this aquarium dwarfs the competition.

In preparation for the opening of the new exhibit, the Academy is currently growing corals in its temporary facility at 875 Howard Street. In one tank, which measures 18 feet deep, Academy biologists are growing corals on adjustable racks to determine which species grow best at different depths.

As most of you know, coral need light to live and grow. But light intensity diminishes quickly in water as depth increases. To counteract this challenge, the Academy is installing 120 metal halide lights over the tank. This will help replicate the energy of the tropical sun corals need for survival.

The display is set to open September 27, 2008. For more information about the aquarium and the Academy, click here.
