The green water didn't faze the athletes

Officials said algae is to blame for water in the Rio Olympics diving pool that turned from a crystal blue to a murky green overnight.

Olympians, fans and officials alike were left scratching their heads when they saw the change in the water color at the Maria Lenk Aquatic Center on Tuesday, but officials said in a statement that the transformation is due to a “proliferation of algae” – and poses no risk to athletes, Fox News reports.

“This was because of heat and a lack of wind,” spokesman Mario Andrada told Fox. “We did all the chemical tests.”

Officials said the water should be back to its normal color by Wednesday, according to CNN.

The water looked fine for men’s events on Monday, but when it came time for the women’s synchronized 10-meter, it was a different story.

“I’ve never dived in anything like it,” Britain’s Tonia Couch, who finished fifth, told the New York Times.

The adjoining pool at the center remained its normal, blue color, making the algae-ridden pool all the more noticeable. Tom Daley posted a photo showing the pools side-by-side and wrote, “Ermmm … what happened?!”

The green water didn’t faze the athletes, though.

“The first dive we went out and we thought, ‘Whoa, this is greener than it was earlier in practice,’ ” Canada’s Roseline Filion told the Times. “But we came here with a mind-set of ‘expect the unexpected.’ If the water was going to be orange, blue, green – it didn’t matter.”

It appears that the case of the mysterious green water has been solved, but that didn’t stop Olympics viewers from coming up with their own theories for the transformation.

One Twitter user shared an article about the water, simply writing, “Urine.”

Another user began a Twitter poll, in which he indicated that the water could have been purposely made green to honor the Brazilian flag.
