Found the reason why the Olympic swimming pool turned green after just 1 night

The organizers announced from yesterday that the water in the tank is completely safe, but the PWTAG team did not think so.

After the water change event after only one night yesterday, there was an official result of why the tank water changed from blue to blue as a dark tree.

After 1 night, the pool water changes to green.

While the organizers of the Olympics in Rio and FINA, the International Diving Swimming Water Examination Organization learns the cause, the athletes still have doubts about the safety of the dark blue waters. The whole tank scene made many athletes assess that: "it looks like a swamp in the house".

FINA concluded that the reason for this sudden change of color is because the avocado tank "lacks some chemicals" necessary for the water treatment process. "The result of normal pH in foreign countries, itself has created this discoloration," FINA announced . "We tried water quality and confirmed that the water in the tank is completely safe for the athlete, there is no reason to stop playing."

However, Ralph Riley, an expert of the Pool Water Treatment Advisory Group (PWTAG) said: "If the water turns blue, there is not enough bleach in the water and there is a possibility that there will be some harm. body ". The PWTAG team recommends that athletes not swim in this green water.

This sudden change in color is caused by a "lack of some chemicals" pool needed for water treatment.

The spokesman for the Rio Olympics, Mario Andrada, confirmed that this will not happen again, "the water in the pool will always be green from now on".

Such incidents will affect the image of the Olympics as well as the host city. I wish the organizers kept their promises and did not make bad images of the beautiful Rio city in the eyes of the athletes and tourists.
