Update to my thread.
The good news:
Phosphorous binder treatment may have worked, and there is very little new filamentous algae growing. There are clumps of old algae that wash up that I continue to rake out.

Now there is curly leaf pondweed explosion! Not sure if it is too late to apply Fluridone? Maybe I will try spot treatments with Aquathol K and then revisit Fluridone in the fall if there is still a problem.
