Burgerm what I did find in the feed store is Hy Yield Aluminum Sulfate in a 4 lb bag,
http://www.gardenharvestsupply.com/product/hi-yield-aluminum-sulphate-4-lb-bag. Will this work? From what I gathered from the ehow website all i need is 3.75lbs since 30lbs will treat 1 acre foot.
I'm not doubting your knowledge by any means since this is all new to me, 2 tons of Ag Lime in a 1/8 acre pond sounds like a lot.
