Less than 24 hours after the Olympic diving pool turned an unsettling shade of green, potentially as a result of an algae boom, the neighboring water polo pool appears also to have been overtaken by algae and is turning green.

On Tuesday during the women's synchronized 10-meter platform diving final, the water in the diving pool turned a murky shade of green. Rio officials were unable to explain the color change. However, one diving official believes that the presence of algae caused it.

The color may look nasty, but diving officials said it was not dangerous. Some divers actually went so far as to say that the green water helped their diving, as it allowed them to differentiate between the sky and the water. Others, however, said it made their dives more difficult.

Here's a picture from yesterday of the diving pool next to the water polo pool, which at that time was still blue.

Luckily it's not quite as green as the diving pool — at least not yet.
