I don't know how to post a new thread and this question seems close to mine. I didn't see there are any responses, but that may be me not knowing how to see them. I have a five acre pond, should be around 20 deep in the middle. Stocked 40+ yrs ago with blue gill, large mouth and channel cat. Currently too many stunted fish. I want to rehabilitate the water and fish. First problem is what I'm told is Filamentous Algae. My dad used to spread pellets of some kind and it made the plants wilt and go to the bottom which allowed us to fish from the banks without having to clean the lures after each cast. WHAT IS THE LATEST TREATMENT Y'ALL RECOMMEND? Thanks.
