The Seas with Nemo and Friends pavilion at Epcot will have delayed openings while repairs are made to tank systems. The delayed 11:00am openings of the pavilion are currently scheduled for October 11-14, 2011.
Problems with the reef tank systems caused an unexpected closure of the pavilion back on October 7, 2011, and Disney has been racing to find a solution since then. On the October 9 I posted an update on my own little blog, The Epcot Explorer’s Encyclopedia, as the first details of the extent of the problems of the pavilion’s marine systems were coming to light. You can head over there if you want a better understanding of the history of the pavilion’s systems and how this isn’t the first time the infrastructure of the marine environment has caused serious problems.
Otherwise, be aware of the delayed opening schedule (shouldn’t you be getting a FASTPASS for Soarin’ and Test Track at that hour, anyway?) and the possibility of further closures/delays as Disney works to solve the tank problems. Additionally, some tank inhabitants have been temporarily relocated to the backstage holding tanks while the system is repaired; that means there will be fewer fish on display.
