RIO DE JANEIRO -- Green, not gold, was the color of the day at the Olympic diving venue.Sure, China won its third consecutive gold medal Tuesday, but the buzz was about the murky green color of the water in the diving pool.That was in stark contrast to the pools light blue color the previous day and the clear water in the second pool used for the water polo competition at Maria Lenk Aquatic Center.British diver Tom Daley, who earned bronze in mens synchronized 10-meter on Monday, tweeted a photo of the two pools next to each other, along with the caption, Ermmm...what happened?!Water quality has been a major issue surrounding the Rio de Janeiro Olympics, but in the ocean and lagoons, not the pools.A statement from Olympic organizers said water tests were conducted and that there was no risk to athletes. They couldnt explain the color change, but said its being investigated.Rio spokesman Mario Andrada said the green was caused by a proliferation of algae.This was because of heat and a lack of wind, he said. We did all the chemical tests. The pool will be blue tomorrow (Wednesday).If it were green and yellow, we would know it was a patriotic thing, Andrada joked, referring to Brazils national colors.Canada team leader Mitch Geller suspected the cause was algae that multiplied quickly in the days warm and sunny conditions.Everybody was scratching their heads going, Whats going on? he said. I think that the filter is busted, but Im not sure. Its not really dangerous. Its not like its toxic or dirty or any of that. It seemed to get worse over the course of the competition.The kale-colored water wasnt just a cosmetic nuisance. It was so dark that divers couldnt see the bottom of the pool.Theyre used to seeing the water, Geller said. The visuals are really, really important in diving.Chen Ruolin, who teamed to win gold with Liu Huixia, said it didnt affect them.Paola Espinosa of Mexico, competing in her fourth Olympics, noticed the pool getting increasingly darker throughout the six-round competition. But she said the water didnt smell or affect her skin.I havent seen anything like it before, Espinosa said. But its Brazil and everything is green down here, so maybe it was a decoration to make it look pretty.American Jessica Parratto wears contacts and said the water didnt burn her eyes.Bronze medalists Meaghan Benfeito and Roseline Filion of Canada tried not to laugh as they gazed at the water from atop the 33-foot tower. They liked that the dark green color offered a helpful contrast with the blue sky.The only thing we said is dont open your mouth in the water, just in case, Benfeito said.Geller said a Canadian pool expert was coming in Wednesday and he would offer to help Rio organizers chemically treat the water if theres a problem with the filter.I dont know what its going to look like tomorrow, he said. I hope its not a swamp. Matt Mantei Jersey .Y. -- The Buffalo Sabres have placed centre Cody Hodgson on injured reserve and recalled two players from their AHL affiliate in Rochester.
