An adjacent pool, being used for water polo and synchronised swimming, has also started to change colour. "We confirm that diving training in Maria Lenk Aquatics Centre's pool is cancelled this morning," Rio 2016 said in a statement. The organisers responded by putting more chlorine - a chemical that kills algae and helps to keep water blue - in the pool and its neighbour but water polo players later complained about stinging eyes.
