• Rio officials did not know why the pool was changing like water from the Amazon River
  • Change in color might be due to algae in the water
  • Television viewers may think there’s something wrong with the TV screen

The five-meter diving pool, which was a normal blue color during the men’s diving events of Rio Olympics held on Monday, turns slowly greener as the competition goes on.

Rio officials at the Maria Lenk Aquatics Center admit they did not know why the pool was changing in shades of green that looks like water from the Amazon River than the usual pristine pool water.

Speculations, however, point out that the change in color might be due to algae in the water, or perhaps the pool lacks of chlorine.

But what is strange is that the water in the adjacent water polo pool across the pool deck remained a normal-looking blue.

Other speculations suggest that pool in outdoors can accelerate algae growth as the water is exposed to the sun.

When compared to water used in pools for swimming, the water in diving pools is kept five to ten degrees warmer. Thus, warmer water is more conducive to algae growth which could best explain why the diving pool turned green.

Regardless of the bizarre, the divers did not seem so bothered with the water’s green color.

Diving events continue on Tuesday with the women’s synchronized 10m diving finals when the water in pool began to turn green.

BBC commentators, on the other hand, inquired to the event organizers why the pool turns in shades of green, stressing that television viewers may think there’s something wrong with the TV screen.
