Shorty I had a similar issue occur in my main pond - treated coontail a wee bit too much and nuked beneficial macrophytes [American Pondweed, Sago, etc.] and corresponding algae bloom was dense and perpetual even through Winter. Then the GC started rooting and experienced turbidity which exacerbated the water quality issues. I finally needed a Alum/Lime/Cutrine treatment via Rex to set things back in balance. Clarity restored, beneficial macrophytes returned, and so far no sign of the coontail returning. A cutrine treatment to knock down you bloom this spring in order to get vegetation established again may be helpful?
