In the past few months, The Seas with Nemo & Friends pavilion has had some quite important problems in the main tanks of the aquarium. They've even shortened the pavilion's operating time at one point, but as we reported some weeks ago, the pavilion is now back with its normal opening times. Unfortunately, it looks like they are still working on some issues. Take a look at this advisory:
Advisory ~ Maintenance Work at The Seas with Nemo & Friends
We are using [specific] equipment to check water samples as part of our ongoing maintenance work in and around the aquarium at The Seas with Nemo & Friends.
So, when you'll visit the pavilion, you may see some pieces of equipment inside the tanks. In that case, don't worry. They are currently doing maintenance work around the area, and they're not going to hurt the animals.
