An official says practice at the Olympic diving pool was canceled in order to keep the water still so the now-green pool would return to its blue color.
But Simon Langford, media venue manager at Maria Lenk Aquatics Centre, says training has resumed and preliminaries of women's 3-meter springboard will go on as scheduled later Friday.
The pool remained green early Friday afternoon.
Langford says the decision to cancel practice was supported by FINA, the sport's world governing body.
Some divers have complained they were not given advance notice of the pool's closure.
The diving pool's water turned a murky green earlier in the week midway through the synchronized events. The unusual color later spread to the water polo pool next to the diving pool, although it wasn't as pronounced.

Harting's younger brother Christoph went through as third.

The decision followed a high-stakes hearing Friday in a packed courtroom in the eastern city of Arnhem that was the latest twist in 33-year-old Van Gelder's turbulent sports career which, alongside his 2005 world title, has also featured a ban for cocaine use and being dropped from a Dutch World Championships team for alleged drug use.
Van Gelder had argued he was unfairly thrown out of Rio by team managers on Monday for late-night drinking and missing an early morning training session.

Egyptian judoka Islam El Shehaby was loudly booed at the Rio de Janeiro Olympics after his first-round loss to Israel's fifth-ranked Or Sasson, when he refused to bow or shake Sasson's hand, in a major breach of judo etiquette.
Sasson defeated El Shehaby with two throws for an automatic victory, with about a minute and a half remaining in the bout.
Afterwards, El Shehaby lay flat on his back for a moment before standing to take his place before Sasson, in front of the referee. When Sasson extended his hand, El Shehaby backed away, shaking his head. El Shehaby refused to comment afterward.
Judo players always bow or shake each other's hands before and after the match as a sign of respect in the Japanese martial art.
El Shahaby had come under pressure from Islamist-leaning and nationalist voices in Egypt to withdraw entirely from the fight.

Friedman apologized further on Twitter, saying: "I'm sorry everyone. I blew it. No excuses."
Phelps' win was his fourth gold in Rio and his 22nd overall in the Olympics. Lochte finished fifth, nearly 3 seconds behind Phelps.

Winning a gold medal in soccer and not worrying about anything else is no longer good enough for Olympic host Brazil.
Brazilian officials say the country now wants to win as many events as it can and finish in the top 10 in the number of overall medals won - a goal some observers believe may be a tall order.
Adriana Bahar of the Brazilian Olympic Committee tells The Associated Press that "of course, soccer is a passion in Brazil ... but now we want to focus on the 41 other disciplines in the Olympics."
Brazil has won three medals so far - one of each color. But the Rio de Janeiro Olympics have yet to catch on across the sprawling metropolitan area of 12 million. Stadiums for basketball and judo have been full but many other venues have been lightly attended. Golf appeared to have more rules officials than fans on its opening day.
