No filter needed.

Despite Olympic organizers’ assurances that the murky green water in its diving pool would “return to normal shortly” the water at the Maria Lenk Aquatics Centre was looking more emerald than ever on Wednesday.

Diver Abby Johnston, set to get back in the pool Friday for the women’s 3m springboard, shared a photo of her concerned face in front of the questionable waters and asked, “If I turn the color of Shrek, will you still be my friend- y/n?”

The silver medalist added that there was “#nofilter on the picture or apparently in the pool.”

While Rio’s organizing committee has insisted that the green water poses no danger to athletes’ health, many athletes have expressed hesitance to jump in to a pool that looks more like a swamp. In addition to the ick factor, diver Tonia Couch told told reporter Martyn Ziegler that she couldn’t see her dive partner under water.

FINA, the world governing body for swimming and diving, issued a statement explaining that the water’s discoloration happened because “the water tanks ran out of some of the chemicals used in the water treatment process.”

While organizers have assured athletes and the public that the pool will soon return to normal, many on social media offered Johnston some sage advice on how to deal with the water: “Keep your mouth closed.”
