That only happened to me when the third section (that pumps back to the tank) had the same water level as the middle section (with the algae). The water became too stagnant. Once the level on the left droped and the water flowed over the edge faster the cyano went away. The speed of the surface of the middle section was too fast for it to catch hold.

I hope that helps I'm sure everyone will have their own remedies.

I would siphon all of the cyano and put a power head in there on get some water movement.

Using a ladel, scoop off what you can and into a bowl. Pressing your macro algae down will help get the surface moving again. Looks like you need to prune anyway.

You have more than cyano bacteria there. Looks like dinoflagellates to me as well. More flow will help, but try to remove as much as you can for the next few days. It should clear up on its own.
