I have not had a lot of experience with it. Only some.
Any wave action helps keep it from spreading so bad. Wind, waves, aeration ripples, all help somewhat. But not a lot.
I used a landscape rake to pull out the worst of the shallow area. We then had a cold snap and the algae seemed to back off. Now just have s amall amount around the edges.
It may come back with a vengence. I just don't know. But right now it is behaving.
That is not much help, but as much as I can give you.
