My pond had issues with algea, previously.
Through changes in what's getting into the pond, adding aeration, and a one time application of Cutrine, I've greatly reduce the algea.
Now, though, Duckweed has taken over.
I'm happy that it reduces the chances of more algea, by keeping out light. Is there a reason I should have it more controlled, other than for aestetics?
Any negative effects to having fish, because of it, when I do get it stocked?
I hate to use more chemicals.
