Is there a trick to that post Stormblood fight?

Hey all! Didn't wanna get too specific in title for spoiler reasons. But basically, I'm at that Qalyana fight in post Stormblood with the aether bubbles. I know you're supposed to use the duty action, but I was getting overwhelmed by the amount being thrown around and unable to de-aetherize them all. Is there some sort of trick to this?
