As British diver Tom Daley pointed out Tuesday, something looks...different about the Olympic diving pool.

Compare the diving pool on the right with the water polo pool at left.


One British diver even said the pool was so murky, she couldn't see her partner underwater.

People watching the divers had questions, and journalists in Rio couldn't immediately get answers.

.@TeamGB girls doing well in diving, battling for a medal in a very green pool! Did someone forget the chlorine tablets last night?

No-one will give an explanation for the green diving pool. An official statement from Rio2016 is being prepared!!!

BuzzFeed News has reached out to Rio officials for more information.

Someone is going to get out of this green pool and be bald. Or a mutant. #Olympics


The shade of green looked a little familiar.

According to one pool manual reviewed by BuzzFeed News, cloudy green water is usually the result of an algae problem.

A disinfectant or algicide can clear up the problem.

Another possibility for blue-green water is the presence of copper ions in the water. This can be the result of a bad pH balance in the water and requires the addition of a sequestering or chelating agent to remove the ions.


By the way, China's Ruolin Chen and Huixia Liu won the gold medal.

Malaysians Jun Hoong Cheong and Pandelela Rinong Pamg won silver, and Canadians Meaghan Benfeito and Roseline Filion took the bronze.
