According to a Jan 27, 2011 report in Crain’s Cleveland Business:
“An e-mailed invitation is announcing the Feb. 2, 2011 groundbreaking for the $33 million first phase of what’s being called the Greater Cleveland Aquarium. It will be housed in the Powerhouse on the west bank of the Flats.
The aquarium is a joint venture of Cleveland’s Jacobs Entertainment Inc. and Marinescape NZ Ltd. of New Zealand. The centerpiece of the 70,000-square-foot complex will be the SeaTube, an acrylic-walled passageway that will allow visitors to walk underneath the marine environment.”
