I am going to be trying to clear my 1 1/4 acre pond with gypsum. I need to know how to spread/disperse it. After researching it shows I need about 1800 pounds and I am not sure how to spread it out. Thanks for the help.

1 1/4 acre L shaped pond, 6 to 9 ft deep. Finished 7/7/16. Stocked with LMB, HBG, BG, CNBG, RES, FHM. Can't wait to fish it. GO SAINTS!!!
