I called my local feed store to ask if he carried any alum, he said he only carried Copper sulfate and it was a very strong and great working product to clear ponds, does anyone ever use or heard of this. Also i mention erossion hay and he said it was just lod trash weed hay and he some oak leaf bales that are a year old for 8.95 a bale. The copper sulfate comes in a 3-4 pd jar that is granules. Which should I try first? Or Both. And do I need to diconnect my aeriator(windmill style) and let things settle down after applying.
