Hello,
I have a 3/4 acre pond well aerated. Gets some fertilizer runoff from neighbors. Had an algae bloom this spring. Filamentous Algae. Im getting under control now but was looking into phosphate reducers. Don't necessarily want to use the aluminum sulfate. I came across "Natural Phosphate Binder" from Easy Pro. Appears to have calcium and magnesium to bind phosphate. Has anyone tried this?? Any success??
