More gossip on Green Water Gate. An American photographer in the press room suggests that perhaps organisers did not "shock" the water overnight.
"You know, it's like back home, if you don't shock the pool water it turns green. It doesn't look nice, but it isn't dangerous," he says.
If chlorine levels drop, even for one day, it can turn green because of an algae outbreak. Having never owned a pool let alone needed to clean one, I just nod sagely.
