Hosts Spain dominated the final day of the International Swimming Federation (FINA) Artistic Swimming World Series leg in Madrid, claiming victories in both events that were held.
The day started with success for home duo Paula Ramirez and Sara Saldaña in the duet free routine final.
They managed a score of 89.9332 points at the Swimming Center M-86, performing a routine that was choreographed in 2016.
Belarus' Iryna Limanouskaya and Veronika Yesipovich finished second with 83.5332 points, while The Netherlands' Noortje de Brouwer and Bregje de Brouwer came third with 82.2332.
"We are proud to show a duet free routine that was performed at the Olympic Games by two stars, Gemma Mengual and Ona Carbonell," Saldaña said.
Ramirez added: "Gemma and Ona are very soloist and very plastic.
"I think our strong point is speed, strength and also expression so accelerating the music, due to our conditions, was a good decision."
Spain’s Berta Ferreras and Pau Ribes were the only contenders in the mixed duet free routine final.
They scored 85.0332 points to give their country another gold medal.
Spain clinched as many titles, seven, as events it entered across the three days of competition.
They also triumphed in the team technical, duet technical, mixed duet technical, free combination and team free competitions.
"We leave with good feelings," Mayuko Fujiki, head coach of the Spanish team, said.
"This gives us motivation to continue working hard over the next two months."
The next leg of the 2018 FINA Artistic Swimming World Series is due to take place in Surrey in Canada from May 31 to June 2.
