I love being at my ponds and I know what I do does not work for every one. When I refurbished, " mucked out" my big pond on my moms property I spent a year non stop removing FA next year I had chare so thi k you could walk on it. Pulled it out non stop. Past two years the pond has been pristine . Added grass carp and have aeration but I believe as I removed the plants nonstop I removed what ever nutrient load that was in the pond. I can't argue with the success .
