200 lbs. should clear your pond to at least 18-20 inches of visibility. I just used 170# for 2/3 acre, but 8 ft average depth. Followed with 100# hydrated lime. Put in 70# alum, #50 lime, it went from 8 to 18 inches. 2wks. later, put in #100 and #50 more lime, it went to 30 inches. Hydrated lime does not change the ph as drastically as I was led to believe. Your pond will be fine. If you have an aerator, mix the stuff up a little at a time in a 5 gal. bucket and spread. Use the aerator for a couple hrs. Same with the lime. Then turn it off and wait. If no aerator, if you have a jon boat and trolling motor, turn it hard over and spin around.
PS...aluminum sulphate damn hard to find in quantities.
