The Cutrine granuals work good, but they are not a "once and done" proposition. The algae will come back.
But where you are mostly worried about the dock area, it is a quick fix and you could just treat the area around the dock. That will work unless other areas get bad enough that the FA blobs up and the wind blows it to the dock. Treating around your whole pond that size would not be cheap. Treating around the dock and a ways each way from the dock not bad.
The trick to controling it, in my reading learning and also experience, is you need to treat early. If you wait till it already appears to be a problem, you are already behind the curve.
When the water first starts warming in the spring, the FA starts growing on the bottom. It may have already started as warm as recent weather has been. Treat it as soon as you start seeing it. It will die quickly and the treatment will last several weeks. Then when you start to see regrowth, you will need to treat again. Probably 2 to 3 times a season.
You have a beautiful lake.
