The situation at the Rio Olympic diving pool seems to have worsened instead of improved.
After officials said they had the mysteriously green water figured out and would have it resolved, the pool was closed on Friday.
British diver Tom Daley seemed to give the first report of the diving pool closing, tweeting Friday morning:
Diving pool is closed this morning. Hopefully that means we haven't been diving in anything too bad the last couple of days! ??????

USA diver Abby Johnston also noted that it was closed.

While it doesn't seem to have been officially announced by Rio organizers, it's now being reported by journalists as closed, with a new development about the smell of the water.
The Olympic diving pool has been closed again because of water quality issues...a German diver says "the whole building smells like a fart"

Rio officials said on Wednesday that the color change was due to a chemical imbalance that changed the pH levels. They insisted the water was safe to swim in and would return to its blue color Wednesday night.
Here was the pool as of Thursday, August 11.

It seems this problem is worse than anyone expected.
