Just a day after the diving pool turned green at the Olympic Aquatic Centre, the adjacent water polo pool has met the same fate.
However, officials and spectators do not find themselves in a hurry to source the cause of the incident, as it was yesterday revealed by Mario Andrada that the greenness was caused by a proliferation of algae.
Alternatively, the International Swimming Federation (FINA) have given their approach as to why the water has turned green.

They said the diving pool had run out of chemicals used in the water treatment process, which then led to the pH level being outside the usual range, resulting in the discoloration.
Rio 2016 officials have declared that despite the discolouration of the water, athletes are completely safe and at no risk what so ever.
An official spokesperson for the Olympics has revealed that the colour of the water in the diving pool should be rectified soon.
During their statement, they added that more could have been done to prevent the mystery occurring in the first place.
An official said: "The people in charge could and should have done more extensive tests during the day - we probably failed to notice what would happen over time."
Just as the problem looked to have been solved, the water polo pool began to turn a murky green on Wednesday night during a men's match, however, the nearby swimming pool is yet to turn colour.
The temporary Olympic Aquatic Centre facilities were established in 2007, which has its own filtration system.
