I initially treated with Cutrine plus,
Be advised I am a total rookie, but I'm trying the
Cutrine Plus granules on one of my ponds.
Thus far I am very pleased with how well Cutrine Plus
has worked on the algae.
Someone told me a product called
Navigate granules
works well on the troublesome aquatic plants like water milfoil, coontail, and spatterdock.
I may try it after some additional reading up.
