A public aquarium had to be closed for a day while cracks in a giant marine tank were repaired.
The fracture on the 200,000 US gal (around 166,500 UK gal) aquarium at The New England Aquarium in Boston, Massachusetts, was discovered by staff on the inner pane of a 120 x 180cm/4 x 6' high, 5cm/2" thick laminate window, comprising three separate sheets of glass.
The Giant Ocean tank is home to turtles, sand tiger sharks, barracuda, stingrays, moray eels and hundreds of reef fishes.
There was no leak from the crack, but estimated repair costs could be as much as $20,000 (not to mention the loss in revenue from the Aquarium having to close for the day).
Workers had to drain 180cm/6' of water from the 23' deep tank in order to repair it, but luckily the location of the crack meant that none of the aquarium's inhabitants needed to be removed. A solid opaque panel has been temporarily installed.
